Can a transmission case be transferred to a transmission seal?
Transfer Case to Transmission Seal. If the leak is external (leaking out and puddling on the floor) the transfer case needs to be unbolted and split from the transmission just enough to uncouple the splined shaft to replace the ring seal/gasket. This may be able to be done without completely removing the transfer case from the vehicle.
What causes transmission fluid to leak from transfer case?
I have a 98 K1500 Z71 with a 350 and auto transmission (4L60E I think), that has been losing transmission fluid. A transmission shop said it was probably a bad seal between the transmission and transfer case, because there were no external signs of leaking.
When to replace a transfer case output shaft seal?
If your vehicle continues to leak oil from the transfer case after replacing the transfer case output shaft seal, then you may need to get a professional to take a look at the transfer case. If the problem persists, get one of the certified technicians at YourMechanic to inspect the transfer case and diagnose the problem.
What does the ring seal on a transfer case do?
That is intended to keep the transfer case oil INSIDE the transfer case and the transmission oil OUT of the transfer case. There is also a square cross-section ring seal/gasket which seals the connection between the two to keep anything from leaking out.
