Like Klaus said having a tranny shop do it you will end up with better parts. My truck has been in the shop going on three weeks now for the same problem. They do not know what caused the failure. I only had 17k on mine when it went. I am getting a remanufactured tranny out of it but like I said it has been three weeks. Granted, almost two weeks of it has been waiting for the new tranny to be shipped to HI. It should be in today or tomorrow. Wish you the best of luck on this endeavor.
