The Pontiac Trans Sport, along with its siblings the Chevrolet Lumina APV and Oldsmobile Silhouette, were a trio of minivans that débuted with radical styling in fall 1989 as 1990 models..
Background
General Motors first attempt at producing a minivan to compete with the Dodge Caravan and Plymouth Voyager, the body-on-frame Chevrolet Astro and the GMC Safari failed to make a noticible dent in Chrysler's almost total dominance of the minivan market in the late eighties, so this second attempt was made. The Pontiac Trans Sport and its sibling models, while more successful than the Astro/Safari duo in terms of market share, had significant perceived flaws that the public couldn't get past in a big way.
Original Concept
First shown to the public in 1986, the Pontiac Trans Sport concept car was extremely well received. It featured futuristic styling, individually removable bucket seats with built-in stereo speakers, a gull-wing rear passenger door and extensive use of glass including a glass-paneled roof as well as many other "dream car" features.
Based on the warm recption the concept vehicle received, the Pontiac Trans Sport was approved for production, but as is often the case, the styling and features showcased on the concept did not make the translation to the mass-produced edition. The gullwing door was deemed too expensive to produce and would probably have imacted overhead garage doors in suburban garages. The glass roof was too heavy and too expensive, so the resultant production vehicle made-do with high-gloss black painted panels for the roof to suggest the glass canopy the concept sported.
Chevrolet and Oldsmobile were also given production vehicles based on the Trans Sport in order to cover the widest possible range of potential customers. It was intended that the Lumina APV would be the value-priced version, The Pontiac Trans Sport would net the more "sport & style" oriented buyers, and the Oldsmobile Silhouette would be the minivan for the premium, luxury market.
Technology/ Innovative Features
Assembled in the now extinct General Motors Tarrytown, NY assembly facility, these U Platform vans consisted of a galvanized steel space frame wrapped in composite plastic body panels that were impervious to rust and minor dents and dings, a manufacturing technique developed on the Pontiac Fiero and used extensively on General Motors’ Saturn line of vehicles.
The Trans Sport was available with seating for seven, with the five light-weight (34 Lb.) rear seats being individually reconfigurable and removable. In 1994 built-in child seats were added to the option list, which provided the ability to switch two of the rear seats between adult and child seating with the pull of a seat-mounted tab.
Included with the level ride package, which utilized a compressor and air-pressurized rear shock absorbers to maintain vehicle height regardless of load, was a control panel and air hose kit that allowed the vehicle to be used to inflate tires, air mattresses, sporting equipment and the like.
In 1994, a remote-controlled power sliding door feature was added, a General Motors innovation, which is now found in almost every other minivan available.
For the 1994 and 1995 model years traction control was available with the 3800 engine option.
Modest Sales Success
The design of these mini-vans was controversial. At the time that the Pontiac Trans Sport and its siblings were conceived, no one had tried to market a stylish or sporty minivan, and GM felt that this represented a potentially large market segment that the class-leading Chrysler minivans failed to address. They styled these minivans to be lower and sleeker than any of the competing brands on the market. The extremely large, long and sloped windshield and the resultant long distance to the base of the windshield when sitting in the drivers seat made for a disconcerting driving experience until a person could adjust to the "different" proportions. Automotive magazines christened the new minivans "dustbusters" after a certain household appliance that shared a similar side profile.
The first engine in these vans was a meager 3.1 L V6, that produced only 120 hp, which was not up to the task of hauling these fairly heavy vehicles around with any authority.
In 1992, the Trans Sport and its siblings received the 170hp 3.8 L 3800 V6 as an option, which provided much better torque and accelleration for the vans, making them the most powerful as well as best handling minivans in production at the time.
In response to criticism (and relatively modest sales) attributable to the vehicles' avant-garde styling, feedback from potential customers, automotive publications, and even chiding in Chrysler Corporation's advertising, in 1994, the Trans Sport and Lumina APV received a facelift, shortening the nose by 3 inches and toning-down of the cladding to effect a more conventional look. Additionally a ridge was added to the interior dashboard to lessen the perceived distance to the base of the windshield.
Europe, which had grown accustomed to sleek people-movers thanks to the Renault Espace, did not object the the futuristic styling, and sales were respectable, so the decision was made to retain the original shape on the Euro-version which from 1994 model year onwards was an Oldsmobile Silhouette, transformed into a Pontiac Trans Sport by the addition of Pontiac badging and wheels.
Production of this generation of U Platform minivans ceased in 1996, at which time the Tarrytown, NY Plant which produced them and had been in operation since 1900 was shuttered and scheduled for demolition.

1997 - 2005 2nd Generation: See Pontiac Montana
In the 1997 model year, the Trans Sport and its siblings got their first major redesign, ditching the one-of-a-kind construction and look to create a more conservative, conventional minivan. Gone were spaceframes, plastic body panels, and sleek styling. The new minivans were of unibody steel construction and styling was intentionally conventional to such an extent that contemporary reviewers remarked that without looking closely at the badging and grille treatments, these minivans could be mistaken for their primary competitors, the Dodge Caravan and Plymouth Voyager, which at the time commanded a 50% share of the minivan market. Along with the roll out of this new generation of people mover, Pontiac debuted a "Montana" option package for the Trans Sport with special cladding and wheels intended to give it a more rugged SUV-like appearance.
Production of this generation was performed at GM's Doraville, GA. facility.
In the 1999 model year, the name Trans Sport was discontinued in favor of the name Pontiac Montana due to the popularity of the "Montana" appearance package, which by the time the "Trans Sport" moniker was dropped, accounted for over 80% of total Trans Sport sales.
