2002 Chevrolet Silverado Z71

Asked by Zachary Mar 25, 2021 at 09:17 PM about the 2002 Chevrolet Silverado 1500 Extended Cab 4WD

Question type: Maintenance & Repair

So I have the truck and we installed a rebuilt trans from a
2005 z71 into my 2002. It was working fine before swap.
Now after the install the trans Jerks into gear. It seems
like it does not have enough power. It also revs really high
before it Jenks into gear. I don't think it shifts past 3rd.
Also speedometer does not work now and getting a code
for it.

Most likely the computers need to be flashed (reprogrammed). The best place to have that done is your local Chevrolet Dealer. Hope that helps! Jim
