I need some opinions - when I drained my tranny (3 speed, 46 pickup) to remove the torque tube, only about 2-3 ounces of oil came out the lower hole. There was no oil in the u-joint housing. When I bought the truck from a dealer 6 mos ago I asked them to change the fluids (dumb, should have done it myself). Because I first had my garage repared, then puttered around with adding turn signals, etc. I've only driven it about 60 miles since I purchased. All the times I drove it it shifted fine, stayed in gear, synchro worked. Do you think it is permenantly ruined? Suposedely it was rebuilt about 5000 miles ago. Thanks.
