Engines
LG6 Engine, 3.1L V6, electronic fuel injection 1990–1995
with the 3 speed automatic; Wikipedia's Trans Sport infobox gives LG6 for the generation, its first-generation section gives the 3.1L V6 from launch until it was replaced for 1996, and its 60° V6 article lists the Trans Sport 1990–1995 under LG6; 1990 from the dealer specifications powertrains page (ordering code LG6; model year 1990, dated September 1989); 1992, 1994 and 1995 from the power teams pages' engine code line; the 1993 power teams page prints LGG, so 1993 is cited from the single-condition remarks on the 1993 optional-equipment weight page ("W/3.1L Engine, LG6") on the engine block heater lines; 1991 from the MVMA engine page (p.25) and electrical page (p.37), which print model year 1991 (issued 6-90) and the engine code line "Electronic Fuel Injection RPO LG6" for the 3.1 liter V6; the 1991 MVMA axle page (p.31) prints its model-year field as 1901 and the 1991 dealer powertrains page (p.5) prints its heading as 1951, so neither is cited; shared U-body code; cited from the Chevrolet Lumina APV kit

L27 Engine, 3800 3.8L V6, multiport fuel injection 1992–1995
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

Factory-verified
LA1 Engine, 3.4L V6, sequential fuel injection 1996
the only 1996 engine, with the M13 4 speed automatic: Wikipedia's Trans Sport infobox gives LA1 for the generation, its first-generation section says the 3.4L V6 replaced both earlier engines for 1996, and its 60° V6 article lists the Trans Sport 1996–1998 under LA1 (1997–1998 belong to the second generation); the 1996 power teams page prints LA1 as its only engine code; shared U-body code; cited from the Chevrolet Lumina APV kit

Transmissions
MX1 Transmission, 3 speed automatic 1990
with the LG6; the 1990 dealer specifications powertrains page (model year 1990, dated September 1989) names the THM 125 3 speed automatic and prints its RPO code as MXI; matched to the unit by meaning: Wikipedia's Trans Sport article names a 3 speed (3T40) automatic, the sole transmission at launch, but prints no code; 1991 is left out because the 1991 dealer specifications page (p.5), which gives MX1 for the THM 3T40, prints its model-year heading as 1951 (OCR) and only a January 1991 issue date, so its model year is unreadable; the MVMA pages give the 3 speed automatic as MD9 (see MD9); shared U-body code; cited from the Chevrolet Lumina APV kit
GM Heritage factory kit — 1990 Chevrolet LuminaAPV, p.6.
Single-source
MD9 Transaxle, 3 speed automatic 1992–1995
with the LG6; the MVMA power teams pages print it on the transmission line as "MD9 Auto", 3 speed; 1991 is left out because the only 1991 page printing it, the MVMA axle page (p.31, "Automatic Trans (MD9)"), prints its model-year field as 1901, and its MVMA-91 footer form number does not date a page; matched to the unit by meaning: Wikipedia's Trans Sport article names the 3 speed (3T40) automatic from launch and retires it for 1996, and its THM 125 article puts the THM 125 in the U-body vans 1990–1995 with the LG6, but neither prints a code; the 1990 dealer page gives this transmission as MX1 (see MX1); shared U-body code; cited from the Chevrolet Lumina APV kit

M13 Transaxle, 4 speed automatic 1992–1996
with the L27 (1992–1995) and the LA1 (1996), as the power teams pages pair them; matched to the unit by meaning: Wikipedia gives the 3800 a 4 speed 4T60 automatic from 1992 and retires the 3 speed for 1996 (its infobox and 4T60-E article name the 4T60-E, the article for the Trans Sport 1992–1998) but prints no code; the 1992–1995 optional-equipment weight pages also print the transmission's own line; shared U-body code; cited from the Chevrolet Lumina APV kit

Equipment
NW9 Traction control 1994
requires L27; the kit marks it interim availability; matched to the item by meaning: Wikipedia says traction control became an option on 3.8L vans for 1994 but prints no code; 1995 is left out because the 1995 kit page lists traction control without a code; shared U-body code; cited from the Chevrolet Lumina APV kit
