requires M13; 1992: standard on the GT (Wikipedia); Wikipedia's Trans Sport infobox gives L27 for the generation, its first-generation section introduces the 3800 for 1992 and replaces it for 1996, and its Buick V6 article lists the Trans Sport 1992–1995 under L27; the power teams pages print L27 on the engine code line, paired with the M13 4 speed automatic; the 1992, 1994 and 1995 optional-equipment weight pages also print the engine's own line (the 1993 one prints it as 127); shared U-body code; cited from the Chevrolet Lumina APV kit
