I have a 2001 F150 with a 4.6 and 4r70w. The issue I'm having is the engine will sometimes stall when slowing to a stop and will also stall when manually selecting 2nd gear. Otherwise the trans works fine, good positive shifts and no noticeable slipping. I've tried disconnecting the TCC wire and noticed no change other than the converter not locking of course. There has'nt been any codes either and it's been doing this for a few days now. Any ideas, maybe a valve body issue???
