This last May I spent $2400 for AAMCO to rebuild my tranny. It was shifting very hard and the Overdrive light kept flashing. It went out again at the end of July! The manager of AAMCO said that they put the CD4E tranny in alot of vehicles and that when it gets rebuilt they still have problems with it. My went out the second time a day after my cooling fans went. Not sure it that caused it though. I never let it get overheated but still! I think that a brand new unit from Ford is about $2800. Like everyone else says: Check around!
Good luck!
