hi i have a 99 Blazer LS 4x4 auto, and my 4l60e just took a dump on me. i have a t-5 from a 86 blazer 4x4, but with the 2.8. is a swap possible on my 99? what modifications would be needed? thanks!

 

Based on cost only my guess is NO.

A 96+ is designed for the NV 3500 manual transmission.

Tomorrow we plan to fire up our 1998 engine/transmission implant for the first time.

We when from 1998 X with 5-speed behind it to 1998 W VIN's that had a 4WD auto behind it and mated it to another 1998 5-speed with 400,000 fewer miles and physically everything was bolt compatible.

I do not know if a 5-speed 4WD NV 3500 will be a direct bolt in option. I would consider buying a wreck so you have all of the change over parts required.

We found no oil pan or exhaust manifold differences between the X engine from the 2WD 5-speed and the 4WD automatic with the W VIN engine as some stated we would. experience.

 

out of sheer curiosity, where is the speed sensor located on yours? please say transfer case :P
