I just replaced the transfer case in my 02 Avy with a reman from Zumbrota. I did not replace the encoder/actuator motor. I had no issues with it shifting into the different ranges with the old t-case. While testing the functions yesterday after finishing the install, 4 HI goes in smooth. 4 Lo is hesitant to even begin shifting and when it does, it sounds like gears grinding. It did seem to shift into 4 Lo once, but it must have popped out again and started grinding. I did not get any warning lights such has service 4wd or strange lights on the buttons. When I removed the motor from the old t-case, 2wd option was selected. The stub shaft on the new t-case was in the same position and the motor went on perfectly so I assumed it was also in 2wd. Is it possible that it was not actually in 2wd? Or is there some sort of alignment needed for the motor?
I have thought about removing the motor and trying to manually shift it into 4 Lo, but I haven't had time to do it yet. I am also unsure which way to rotate the stub shaft to get 4 Lo.
Any help would be greatly appreciated. I also plan to call Zumbrota to see what they have to say. It is supposed to have a 2 yr warranty.
