I am wondering if anyone can help me out on this one. I have a 1997 dodge with the 47Re. I recently had the trans rebuild by a friend of mind who has worked as Dodge trans tech for 10 years. I purchaced the Goerend valve-body, and single disc billet converter. The trans worked good for the first 4k but now it's starting to act up. If I am towing with it and am heavy on the throttle, and manually turn the over-drive off it will not go back into lock-up after doing so. The first time this happened I shut the truck off and it re-set and worked fine. It happened today again and now I can't get it into lock-up in third, or forth. I have the resistor in lline with the E.C.U, and the brake switch is working properly. Unfourtunatly I don't have access to a scaner @ this time so I can't read the temperatures, or pressure. I have pulled the pan and didn't see any large chunks, just minimal fillings in the bottom of the pan. The fluid is not burnt either. I also have put on a new TPS so that's out of the picture. Any insight would be great. Thks in advance:bang
