99 Jimmy Transmission


Does anyone know the difference between a 4 wheel drive transmission, and the two wheel drive transmission on a ‘99’ Jimmy? Is it just different tailshafts, and if so are they inter-changeable?


I believe both trucks will have a 4L60E transmission. The output shafts will be different between the two, so they will not be interchangeable unless you tear down both and swap shafts.


Yep, just past the sun shell there is a retaining ring which holds the output shaft in. The trans needs to be torn down to this point, a shorter output shaft installed along with a transfer case. Transmission is the same…
