Hi. I'm looking for some insight into a tranny problem I am having. I have a 1995 Explorer XLT 4WD Automatic V6. Had tranny "rebuilt" last week after slipping in several gears and O/D Off light flashing. On the drive home from shop, car is running great for 20 minutes or so, then O/D Off light starts flashing, first gear turns to mush, and I get two noticeable "thunks" during downshift, one at about 15 mph, then again at 10mph. At home, using my hand held code reader, I get fault code 645 "Incorrect gear ratio-first gear". I reset EEC by disconnecting battery and the car ran perfect for maybe 10-15 minutes, then the same symptoms reappear. I do not know how much, if any, of the electronics was replaced or repaired by the "mechanic", so I'm thinking that the "repair" was incomplete, and I have lingering electronic issues that are manifesting as mechanic problems. There are tons of posts related to this, and I have read many, and will continue to read more. I have heard mention of solenoids getting stuck, but don't know if this applies to my situation. Any advise would be greatly appreciated. TIA.
