* 4L80E: This 4-speed automatic overdrive transmission was very common in the C3500, especially with larger gasoline or diesel engines.
* Allison MDT 5-speed automatic: Some heavier-duty C3500s, particularly those with diesel engines, might have used an Allison automatic transmission (likely a 5-speed). The exact model number would vary.
To know for sure which transmission is in *a specific* 1992 Chevrolet C3500, you'd need to check the vehicle's:
* Build sheet/sticker: This is usually found on the driver's side doorjamb.
* Owner's manual: This will list the specifications for the vehicle.
* Transmission case: The transmission itself usually has a tag or casting number that can be used to identify it.
Without knowing the specific truck's configuration, it's impossible to say definitively which transmission it has.
