I need to know what transimissions will fit a 1994 gmc sierria 4 wheel drive extend a cab

for questions like this i usually do this: 1. call gmc parts dept (call a couple of them) ask for a replacement transmission and the price. get their stock number and model number of the transmission. if they give you that you can call around to any transmission shop and verify that they have compared to what GMC told you. have your VIN# ready 2. call some tranny shops ask them if they have a tranny for your make and model. have the VIN# available. 3. go to any GMC/Chevy dealer maint. dept and have them run a VIN# build for your vehicle. it should list a specific transmission. with that info you can shop around as in #1 & 2.

thanks that helps
