1994 GMC W4 Question

mihall · 04-26-2008, 09:46 PM

Can anyone tell me what automatic transmission was used in the 94 GMC W4 cabover with the 350 Chevy engine. Isuzu and NPR are suppose to be similar.

I was wondering if I could ID the transmission IE turbo 400 etc.

Thanks in advance... Mike

The gasoline versions used a Hydra-Matic 4L80E, the diesels used a JATCO. The trucks are the same Chevy W4/GMC W4500/Isuzu NPR.
