the transmission shifting into or out of "park" added as a standard feature of the power door lock option package. Rear portion of the roof, behind the C-pillar previously painted black as standard with body color as a no-cost option, would be only available painted body color as a further effort to "normalize" the vehicles' looks as compared to competitors. 1996 Both 3.1 and 3.8 L V6 engines dropped, a 3.4 L V6 3400 engine became the only power plant available. There were few other changes, due to a completely redesigned 1997 model, to debut in summer 1996. European market The European-market version of the van from 1990 to 1993 had amber rear turn signals, and four small oblong headlamps. For 1992 a new composite headlamp assembly was used. The front turn signals used amber lenses, and side turn signal repeaters are installed. The headlamp washers from 1990 to 1993 were four smaller dome-shaped jets positioned in front of each low and high beams. When North American Pontiac Trans Sport received a mid-cycle refresh with new front design in 1994, the low sales volume did not justify expense of recertifying the new front design and headlamps. Thus, the Oldsmobile Silhouette was rebadged as Pontiac Trans Sport and was sold in Europe until 1996. The headlight washers were redesigned to two single wedge sticks. Pontiac Trans Sport for the European market had two engine and two transmission options: 3.8L V6 engine with 4T60 4-speed automatic transmission and 2.3L four-cylinder Quad 4 (LD2) engine and 5-speed manual transmission (never offered in the North American version). Second generation (1997-1999) 1997–1999 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 the 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. During the development of this generation of the U-body minivan, General Motors extensively benchmarked the then current Chrysler minivans. The resultant vehicles more closely resembled the immensely successful trio; However, Chrysler would launch a completely redesigned
