Yes. As long as both trucks are 1/2 tons and not diesel (if it is Diesel or 3/4 ton let me know). It will bolt in but there are differences. The '89 should have a 700r4/4L60 4 spd (some came with the turbo 350 3 spd) and the '94 should have a 4L60e with the stand alone TCU (tranny control unit) on the inner fender to control it. You will need to grab the linkages and cable brackets off of the '89. The 700r4/4L60 requires a T/V (throttle valve) cable from the throttle linkage on the throttle body to the tranny. The turbo 350 requires a kick down cable like the T/V mentioned and you will need to run a vacuum line from the intake down to the back of the tranny. The stock 4L60e uses the TPS (throttle position sensor) once converted tape up the connector for the tranny as the TCU could be used in the future or sold as parts. CAUTION: Ensure you setup the T/V cable correctly - improper adjustment is a leading cause of tranny failure.

I've got a1994 Chevy Silverado and I took a 1988 it had a 350 motor in it and took it out and put it in the 94 my 94 Ha's a4l60e in it but act's like it wants to change out to fast I thought it might be in the computer so I changed it but still it's not right I thought about putting in a 700r do you think that might be the problem

I've got a 1995 GMC 3500 tranie I want to put it in a 1988 1500 both have 350 in them both ,4wheel drive
