The Pontiac Trans Sport is a minivan that was marketed by Pontiac from the 1990 to 1999 model years. The first minivan marketed by the division, the Trans Sport marked the beginning of a wider transition of moving away from sedans and station wagons as family-oriented vehicles. Marketed between the Chevrolet Lumina APV (the first front-wheel drive Chevrolet minivan) and the Oldsmobile Silhouette (like the Trans Sport, the first minivan by the brand) took its name from a similar 1986 concept vehicle.

The first-generation Trans Sport took on a "Dustbuster" nickname for its controversial front body styling (with a long front overhang); the second-generation version, much like several other model lines, marked an industry shift towards adopting a form factor similar to that used by the Chrysler minivans. Officially designated a U-platform vehicle, both generations of the Trans Sport share mechanical commonality and shared componentry with the W platform Pontiac Grand Prix.

The Trans Sport was initially assembled at North Tarrytown Assembly (Tarrytown/Sleepy Hollow, New York), shifting production to Doraville Assembly (Doraville, Georgia) for its second generation. For the 1998 model year, Pontiac renamed the Trans Sport the Pontiac Montana, after an exterior trim package introduced in 1997.

Background

Following the 1984 model-year release of the Chrysler minivans, General Motors responded with the release of the Chevrolet Astro and GMC Safari for the 1985 model year. Though initially comparable to the Dodge Caravan and Plymouth Voyager in length and wheelbase, the Astro/Safari were heavier-duty vehicles, sharing components with compact pickup trucks and full-size cars. Though the GM minivans were widely accepted in the marketplace (alongside the competitive Ford Aerostar, both passenger and cargo van variants were marketed), the Astro/Safari did not secure as wide of market share as the initial Chrysler model lines.

To compete more closely against the Caravan/Voyager, General Motors began development of a front-wheel drive minivan for the 1990s. Prior to the 1986 debut of the concept car (see below), General Motors approved the design of what would become the APV minivans, with the Trans Sport (loosely deriving its name from the Trans Am Firebird) targeting sport- and style-oriented buyers, while the Chevrolet Lumina APV serving as the value-based offering, and the Oldsmobile Silhouette targeting premium markets.

1986 concept car

1986 Trans Sport concept

At the 1986 Chicago Auto show, General Motors released the Pontiac Trans Sport concept vehicle. Derived from the chassis of the mid-size Pontiac 6000, the Trans Sport concept was nearly 6 inches lower than the Plymouth Voyager of the time. To give the vehicle a far more contemporary exterior, the Trans Sport was styled with blacked-out A-pillars and upswept B-pillars (giving the front row the look of a wraparound windshield). In place of a traditional curbside sliding door, the concept car was designed with a right-side gull-wing door (the driver-side window line was fitted with wraparound glass from the B-pillar to the liftgate). Much of the roof was glass; at its widest point, the headliner was only 36 inches wide. Though highly unlikely for production, the Trans Sport was designed with multifunction taillamps; in addition to traditional red brake lamps and white/clear reverse lamps, the units added amber for deceleration.

The interior of the Trans Sport previewed the 1990s integration of technology into GM vehicles (including multiple Pontiacs), featuring a windshield heads-up display, a multifunction steering wheel, and a primitive form of what later would become OnStar; along with a digital rearview mirror and electronic transmission shifter, and a Nintendo Entertainment System was integrated for the rear passenger compartment.

Though deriving its chassis from the 6000 sedan/wagon, the Trans Sport concept car was fitted with a 235hp turbocharged 2.9L V6 (intended for a stillborn version of the Pontiac Fiero), paired with a 3-speed automatic. 17-inch wheels (the same diameter as the later Corvette ZR-1) were used, much larger than any other non-Firebird Pontiac vehicle of the time.

Introduced for the 1990 model year, the Pontiac Trans Sport was introduced as the first Pontiac minivan; alongside the newly introduced Grand Prix four-door, the Trans Sport was phased in to replace the mid-size 6000. Similar to the Ford Aerostar and Toyota Previa, the Trans Sport used "single-box" body design, with the hood blending into the slope of the windshield. The long front overhang (resulting from the front-wheel drive chassis) led to a poor market reception of the design, as the three minivans quickly became nicknamed "Dustbusters" colloquially (after the handheld vacuum cleaner).

The final vans of this generation rolled off the assembly line on June 27, 1996.

Chassis

The first-generation Trans Sport is a GM U platform vehicle, with GM moving to a specific GMT199 platform code. In contrast to the 1986 concept vehicle (which used a lengthened A-body chassis), the GMT199 architecture employed a galvanized steel space frame, similar in concept as the Pontiac Fiero and the Saturn SL/SW/SC.

For 1992, anti-lock brakes (ABS) was added as a standard feature.

For 1994, traction control was added as an option on 3.8L vehicles.

Powertrain details

In contrast to the turbocharged engine of the Trans Sport concept, the production model line was fitted with a 120hp naturally-aspirated 3.1L V6, shared with the 6000 and Grand Prix; a three-speed automatic was the sole transmission offered. For 1992, a 170hp 3.8L 3800 V6, paired with a 4-speed Hydra-Matic 4T60 transmission (adding an overdrive gear). For 1996, both the 3.1L and 3.8L V6 engines were replaced by a 180hp 3.4L V6; the 3-speed transmission was retired.

Body

Though sharing nearly all exterior body panels, each GMT199 minivan was distinguished by its roofline styling. The Chevrolet Lumina APV debuted with a black roof forward of the B-pillar and a body-color rear roof; the Oldsmobile Silhouette, a blacked-out B-pillar with a body-color A-pillar and roofline. The Trans Sport was fitted with a largely black roof, with a body-color B-pillar; the extensive lower body cladding was a feature adopted from the 1986 concept car (and as part of Pontiac model tradition).

In following with its spaceframe construction, only the roof panel of the Trans Sport is made of steel, with all exterior vertical side body panels made from polymer plastic (similar to Saturns). In line with the concept car, the production Trans Sport has a large amount of slotted body cladding (to protect the body from dents). Though toned down extensively from its 1986 namesake, the production vehicle retained an upswept B-pillars, widely curved glass (used on all windows) with blacked-out window pillars. Along with the adoption of a full-width metal roof and the use of a sliding door, the largest styling change from the concept car saw a different set of taillamps, moving to a vertically-oriented design integrated in the D-pillars. For 1991, a sunroof became a new option; a year later, the external radio antenna was deleted (replaced by a design integrated between the roof and headliner). For 1992, the sideview mirrors were redesigned; along with growing in size, the units now were able to fold inward.

Though the production Trans Sport interior did not adopt many of the high-technology features of the concept car, the model line debuted a modular set of rear seats. In place of the typical two full-length rear bench seats, the rear interior of Trans Sport could be configured in multiple ways to accommodate passengers and cargo, as the rear was fitted with five individual rear bucket seats. Three configurations were offered: five seats (2-3), six seats (2-2-2), and seven seats (2-3-2).

For 1991, the dashboard was revised slightly, as non-reflective carpeted cloth was placed on the portion below the windshield (to reduce glare). In 1992, the Trans Sport adopted an interior feature from its namesake concept car, with steering-wheel radio controls becoming an option.

1994 revision

For 1994, all three GMT199 minivans underwent a mid-cycle revision, largely in response towards the negative critical response towards their exterior design. To further visually shorten the exterior from the three inches removed from the body length, designers installed a new hood (sharing headlights with the Pontiac Bonneville), restyled lower body cladding, and a new front bumper (with a larger, vertical front grille). Rear side glass received a darker tint (visually lengthening the vehicle from the side). As a market first, the Trans Sport (alongside its APV minivan counterparts) introduced a power-operated sliding door; originally slated for 1993, the feature was postponed until 1994 to fix quality-control issues related to the design.

Coinciding with the addition of a driver-side airbag (again using the steering wheel of the Pontiac Grand Prix), the Trans Sport saw revisions to the dashboard; to make the forward edge of the windshield seem closer to the instrument panel, a ridged finishing panel was added. The rear seats were revised, with second-row seats receiving integrated child safety seats as an option. For 1996, air conditioning was made standard equipment.

Trim

At its 1990 launch, the Pontiac Trans Sport was introduced in base Trans Sport trim (distinguished by silver lower body cladding) and the Trans Sport SE trim (body-color lower trim). For 1992, the trims were revised, as the base Trans Sport was discontinued and the sportier Trans Sport GT was introduced (with the 3.8L V6 standard); as part of the change, all Trans Sports became monochromatic. The GT also became the second APV minivan (besides the Oldsmobile Silhouette) available with leather seating (as an option).

For 1993, the Trans Sport GT was dropped after a single year, with all examples becoming Trans Sport SEs for the rest of the generation (with body-color badging); the SE was offered with any content from the GT as an option. As a stand-alone exterior option, a gold-color exterior trim package was offered; with certain colors, gold wheels, badging, and lower body cladding was paired with a body-color upper roof.

During 1995, the black-color roof that was standard (body-color was a no-cost option) was discontinued, bringing it closer in line with its GM counterparts and other minivans.

For 1997, GM released its second generation of front-wheel drive minivans. Following the controversial market reception of the GMT199 generation, the second generation closely adopted the defined "two-box" form factor of the Chrysler minivans, sharing a similar size and layout as the third-generation Caravan/Voyager (released a model year before). In contrast to the Ford Windstar, the second-generation Trans Sport was offered in short and long-wheelbase bodies, with single or dual sliding doors, and was offered through multiple brands.

The Trans Sport was again the mid-range GM minivan, slotted between the Chevrolet Venture (replacing the Lumina APV) and the Oldsmobile Silhouette. After the 1999 model year, the Trans Sport name was discontinued by Pontiac in favor of Pontiac Montana, an appearance package introduced for 1997.

Following the closure of North Tarrytown Assembly, assembly of the model line was shifted to Doraville Assembly in Georgia; the facility closed on September 26, 2008.

Chassis

Considered a U-body vehicle by its VIN designation, the second-generation Trans Sport used the official GMT200 platform designation. The innovative chassis construction from the previous generation was abandoned, largely benchmarking the NS-generation Caravan/Voyager, moving to a more conventional steel unibody with steel body panels. Growing significantly in size, the Trans Sport was now offered in a standard 112-inch wheelbase (2.2 inches longer) and a 120-inch extended-wheelbase chassis (between the Ford Aerostar and the Ford Windstar as the longest-wheelbase minivan).

The suspension used front MacPherson struts along with rear coil springs. As with the previous generation, the Trans Sport was fitted with front disc brakes and rear drum brakes.

Powertrain details

The GMT200 Trans Sport carried over the powertrain from the 1996 Trans Sport, with a 180hp 3.4L V6 and a 4-speed automatic transmission as standard equipment.

Body

1997-1998 Pontiac Trans Sport LWB 4-door (two-tone body)

Moving away from the controversial "Dustbuster" profile, the second-generation Trans Sport was designed with a form factor similar (if not more conservative) than the Dodge Caravan it competed most closely against. As with the previous generation, the Trans Sport was distinguished from its divisional counterparts by Pontiac lower body cladding (painted either in a contrasting color or a matching color, dependent on trim); the split grille was enlarged and moved between the headlamps (a design specific for the GMT200 vehicles, shared by all model lines). As with the Chevrolet Venture, the Trans Sport was styled with a blacked-out B-pillar (for a blacked-out window line).

Coinciding with the closer-coupled windshield, the interior featured a more conservative dashboard layout, with a conventional A-pillar (in place of fixed quarter glass) with reduced surface area between the instrument panel and the windshield edge. Borrowing a steering wheel and various switchgear from the Grand Prix (also redesigned for 1997), the Trans Sport also received its own instrument cluster. The modular seating design of the previous generation returned, with three different available configurations: eight-passenger (2-3-3) and seven-passenger versions (2-2-3, 2-3-2); rear bench seats (split or full-length) were offered in a 2-2-3 configuration.

The GMT200 minivans adopted a dual-airbag dashboard; for 1998, front-seat side airbags were introduced as a standard feature. As an option, the 1998 Trans Sport was the first minivan (alongside its divisional counterparts) to feature OnStar (a modern version of the system fitted to the 1986 concept car).

Trim

Pontiac Trans Sport Montana SWB 3-door

For 1997, the Pontiac Trans Sport was offered in two body lengths and either one or two sliding doors; for 1998, two sliding doors became standard on all extended-wheelbase versions. The standard trim was an unnamed Pontiac Trans Sport, distinguished primarily by monochrome exteriors (or light-color body cladding). The Pontiac Trans Sport Montana was the flagship trim, styled for a more rugged look. In addition to model-specific gray body cladding and standard alloy wheels (with white-letter tires), the Montana was specified with "sport" suspension tuning, and load-leveling suspension (adding a rear-mounted air inflator).

The Montana quickly became the most popular version of the line, accounting for over 80% of total Trans Sport sales. After 1998, Pontiac renamed its minivan as the Pontiac Montana in the United States (1999 in Canada).

Safety criticism

The 1997 Trans Sport crash-tested by the Insurance Institute for Highway Safety (IIHS)

A crash test video of the 1997 Trans Sport/Montana conducted by the Insurance Institute for Highway Safety (IIHS) resulted in some criticism due to extreme damage to the vehicle in the 40 mph (64 km/h) moderate overlap crash test. The minivan received a "Poor" rating and was ranked the "Worst Performing Vehicle" by the institute as a result.

Some comments made by the IIHS after the first test in 1996 were:

• Major collapse of the occupant compartment left little survival space for the driver.
• Extreme steering wheel movement snapped the dummy's head backward.
• The unnatural position of the dummy's left foot indicates that an occupant's left leg would have been seriously injured in a real-world crash of this severity.
• The forces on the left lower leg were so high that the dummy's metal foot broke off at the ankle.

The safety issues of the Trans Sport/Montana were later addressed with the Montana SV6, which earned the highest rating of "Good" given by the institute in the moderate overlap crash test.

The National Highway Traffic Safety Administration gave the van 4 stars for driver protection and 3 stars for passenger protection in the 35 mph (56 km/h) frontal impact test. In the side impact test, it received 5 stars for front passenger protection, and 5 stars rear passenger protection.

Export versions

From 1990 to 2007, GM Europe imported two generations of US-produced minivans under the Trans Sport nameplate. The GMT199 Trans Sport was based on its American-market namesake (and the Oldsmobile Silhouette) and the GMT200 Trans Sport was a Chevrolet-brand vehicle based on the Pontiac Trans Sport (though adopting the body of the later Pontiac Montana, the nameplate was not used in Europe).

First generation (Pontiac/Oldsmobile)

See also: Oldsmobile Silhouette

For European export, the Pontiac Trans Sport was the sole GMT199 minivan, sold primarily through Opel dealers. Several modifications were made to the design to bring the model line in compliance with European lighting regulations, with the rear lighting clusters receiving amber turn signals; the liftgate was fitted with rear foglamps and enlarged reverse lights, along with mounting for wider European license plates. For 1990 and 1991, the European Trans Sport was fitted with exposed quad headlamps (from the R/V Suburban), with amber turn signal repeaters housed in the clear turn signal lenses. For 1992, the American-style composite headlamp housing were introduced (with glass lenses), with the turn signal repeaters moved behind the front wheels. The export version also was fitted with four bumper-mounted headlamp washers (for both high and low beams), replaced by two for 1994.

With the mid-cycle revision of the model line for 1994, the European Trans Sport largely became a Pontiac-badged version of the Oldsmobile Silhouette (retaining the previous hoodline and headlamps). Though the new Trans Sport retained its roofline styling, the model had lost nearly all its lower body cladding and its Pontiac grille (adopting an Oldsmobile-style split grille above the license plate). After the 1996 model year, the export Trans Sport moved to the GMT200 generation (shared with the Opel/Vauxhall Sintra) and was rebranded as a Chevrolet.

The export Trans Sport was initially offered with a 2.3L Quad 4 (LD2) I4 engine paired with a 5-speed manual transmission (a combination never offered in North America); from 1992, the 3800 3.8L V6 and 4T60 4-speed automatic transmission was offered as an option.

Second generation (Chevrolet)

2001 Chevrolet Trans Sport (Pontiac Montana) in Finland

2002 Chevrolet Trans Sport (Netherlands)

The GMT200 generation of the Pontiac Trans Sport was introduced in Europe for 1997, branded as the Chevrolet Trans Sport. With the exception of badging and wheels (from the Chevrolet Venture), the Chevrolet Trans Sport was trimmed identically to its Pontiac namesake. As with the previous generation, the export model line differed from its American-market counterpart primarily in changes related to compliance with ECE regulations, requiring different front headlamps, turn signal repeaters, amber turn signals, and rear foglamps; different seat belts are required, along with multiple other safety-related items.

On the GMT200 platform, both the Chevrolet and Pontiac Trans Sport (later Pontiac Montana) were designed alongside the Opel/Vauxhall Sintra (the first/only Opels built in the United States). Following the 1999 discontinuation of the Sintra in Europe, the Trans Sport largely served as its replacement. After GMT200 production ended after 2005, sales of European dealer stock continued through 2007. Despite limited sales in most of Europe, the Chevrolet Trans Sport was particularly successful in Sweden where it was the best selling minivan for a while.
