Transfer case questions.

[2bit]

Hello! I haven't been on this forum in years since my '94 @!*% the bed.

I now have a '97, auto, 3.3l, and the T-case is giving me grief.

 

I have the rear axle on stands so the wheels spin freely.

P - grinding noise

R - grinding noise only when under throttle.

N - grinding noise

D - grinding noise till about 30-40km, then all good

2 and 1st are ok.

 

All gears shift fine as well as the 4H and 4L

I have felt the t-case while this happens and it is viberating like a mofo. That's why I think its the problem. The fluid was a little low and black. I changed it and still no better. The drain plug had a bit of metal on it, nothing alarming though. The previous owner though the tranny was shot. Tranny fluid is nice, clean and smells like a rose.

 

Any help?
