237 Chevrolet Express transmissions, covering model years 2000 to 2023. On the engine side of this van the fuel is the thing that catches people out - 29% of the Express engines we list are CNG or LPG rather than petrol. On the transmission side it is not. These units are catalogued by the engine they were paired with rather than by fuel, and not one of the 237 is listed as CNG or LPG, so for a gearbox the year and the engine it sat behind are what you match. The fuel question belongs on the engine listings.

Those are the six largest pairings rather than the whole range. The rest of the 237 sits outside them: the 5.0L, 6.5L, 7.4L and 8.1L pairings from the earlier years, and the listings identified by wheelbase or by ID code rather than by displacement. 10 of the 237 carry a diesel designation in the catalogue, while the 6.6L pairing above numbers 24, so match a diesel on displacement rather than on the fuel line.
Why the fuel split does not carry across
A gaseous-fuel Express engine differs from a petrol one in the parts that meet the fuel and the combustion heat: hardened valves and hardened valve seats, because gaseous fuel burns dry, and a fuel system with nothing in common with a petrol rail. None of that reaches the gearbox, and the catalogue reflects it - Express transmissions here are identified by displacement and year, not by fuel. If you are matching a transmission behind a 6.0L, the GM 6.0L V8 engine guide is still the page that tells you which 6.0L you have, including the eighth VIN character B that marks the gaseous-fuel LC8.
What these cost
Express transmission listings start at $1,139, and the median across all 237 is $2,775. A median above the engine collection's is not a mistake: this group starts in 2000 rather than 1996 and runs four years later, so it is a newer set of parts on average.
How to narrow it down
Give us the model year, the engine displacement and whether the van is two- or four-wheel drive, and send the VIN with your enquiry. Displacement alone is not enough on this van - the same displacement spans more than two decades of listings here.

Chevrolet Express used transmissions - frequently asked questions
Which transmissions does this collection cover?
237 Chevrolet Express transmission listings across model years 2000 to 2023. The six largest pairings are behind the 4.3L V6, 6.0L V8, 5.3L V8, 4.8L V8, 6.6L Duramax and 5.7L V8, and the table above gives the count behind each.
Are any Express transmissions CNG or LPG units?
No. Not one of the 237 listings is catalogued as CNG or LPG. These transmissions are identified by the engine displacement they were paired with and by model year. 10 carry a diesel designation, while 24 are paired to the 6.6L Duramax. The CNG and LPG question applies to the engines, where 29% of the Express listings are gaseous-fuel.
What do I need to tell you to match a transmission?
Model year, engine displacement, and two- or four-wheel drive, plus the VIN. Displacement on its own will not settle it, because the same displacement appears across more than twenty model years in this collection.
What do used Chevrolet Express transmissions cost?
Listings in this collection start at $1,139 and the median is $2,775.
