Third gear burned out...
Well, got my truck from Gulfport and the shuddering is gone. It was the third gear that had burned out just like Buchanans Transmission said. What happened most of the time going up inclines in overdrive it would shudder when it downshifted to third it would stop. Once on level ground it would run just fine. I was passing a fuel truck on cruise at 65 mph and when it downshifted to third the rpm's pegged out...I shifted to neutral turn the engine off. The next day (Monday) I went to Ford...one ahead of me getting repaired and it would be the next day before he could look at it. Done homework the day before with the locals and new the best transmission shop....I went to Buchannans went in ...told the prob. Lee said we'll do it for 1500....ford was around 3000...I aked when can you get to it....middle of next week cause there are twenty ahead of you..now, no rental cars or flights available. Lee Buchannan even got me a ride back to Fla...fine folk they are. Here is a list of what parts were needed: torque converter, P.R. valve, shift solenoid,EPC solenoid, reverse band, OD Band, 1,2,3, excel, inter spring....think they must have rebuilt everything.....I'm happy....hope4 this helps someone....Jim
