can i put my t350 tranny in my 99 blazer 4x4 and what will i need to do it if i can. besides wiring and computer work...

 

Might have to change output shafts. Its the same spline count but doubtful its gonna be the same length. Also the th350 is shorter so gonna need new driveshafts and move or make new crosmember. Not sure if its gonna mess ith your computer. The vss is in the transfercase

 

Either output shaft change or a transfer case swap.

The PCM will have to be reprogrammed to a manual tune so it doesn't complain about not having control over the trans.

 

yeah that sounds right, but im not even sure what the real problem is with mine i replaced the spiders and pininon rebuild everything in the rear end and it chutters still when i reverse is that a reverse drum in the tranny cuz i just had it rebuild 5000 miles ago

 

Have you checked all of your engine & trans mounts?
