New from Mass with a question

[podirtfarmer]

I have a 2002 Sierra that was in an accident it cracked the trans belhousing and the transfer case. My question is I picked up a late 1999 gmc Z71 with a perfect running 5.3 and trans and transfer case. Will these drop into my truck I have the complete donnor truck all wireing and computors any help would be great Thanks

If your have the 5.3 in your Sierra, the 1999 drivetrain should mate right in. If you had the Standard 4.8 vortec, your going to have to also transplant the ECM to run the 5.3 drivetrain.

Good luck and take your time on reconnectin the wire harness to ensure that you have a 100% running engine.
