Can you install a automatic transmission from a 2000 2-wd V-6 silverado 1500 into a 94 4-wd V-8 350 silverado 2500?

Answer 1

Yes, you change those trannys but you have to remove the transfer case and put it on the new one if you want to keep the 4+4. No, because the 2000 would have a 4l60e trans, that is controlled by the ecm, it cannot be shifted by the 1994's ecm. you would have to get something to emulate the ecm to tell the trans to shift. No you can not- Both transmission are designed totaly different. The 94 trans.

will not bolt up to the 2000 year engine and vice versa.
