The 1990 Pontiac Trans Sport emerged from the Pontiac Motor Division of General Motors because it introduced new mini-van features including front-wheel-drive and the transverse front-engine structure. The U-body platform supported the original production of the Pontiac Trans Sport which had a wheelbase of 109.8 inches. The vehicle offered dimensions of 194.5 inches in length and 74.6 inches in width and 65.7 inches in height while its curb weights started at 3,400 pounds and reached up to 3,800 pounds based on selections and equipment choices. Performance enhancements came with three engine choices at the Pontiac Trans Sport: 2.5L I4 followed by 3.1L LG6 V6 and later by 3.4L LA1 V6. The Pontiac Trans Sport implemented the 4-speed 4T60-E automatic transmission that delivered refined gear shifts with superior driving quality than its predecessor. Leather upholstery together with steering wheel controls appeared at the 1992 GT model release to elevate interior features and comfort. Throughout the 1999 production year customers recognized the Pontiac Trans Sport as reliable and capable because original equipment manufacturer parts with high standards were used. The manufacturer's original components for Pontiac Trans Sport vehicles follow strict production guidelines to produce long-lasting characteristics resulting in the enduring market presence of these vehicles.
