2002 Chevrolet Silverado Z71
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.
