HELP with Explorer tranny...PLEASE!!!
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" a couple of weeks ago 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. If I put the tranny in the "1" or "2" position, rather than the "D" position, first gear comes back, and the two "thunks" disappear. The O/D Off light continues to blink, however. Weird!? 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. - Paul |

There should be SOME sort of warranty on their work. Hold'em to it. Mark |

Thx Mark. Yeah, I know. The problem is that this guy is too old school,
and (from what I've been told since the repair) lacks the knowledge or experience to fix advanced electronic transmissions. He should not have taken this job. If I were to guess, I'd say he probably changed the worn mechanical parts, but did not replace any or all electronic components. Again, just a guess, and an unqualified one at that. I have a one year warranty, but I fear I'll end up taking this back every week only to have the same unsatisfactory outcome. Then I'll find myself in Civil Court trying to get my money back. He charged me only $1150, when Lee Myles wanted double that. Lesson learned he Pay half price, get a half @$$ job. Anyway, I figure if I can get insight from others as to what the real problem might be, maybe I can give this guy enough info that even he can fix it. |

First off I have no tranny experience, but if the clutches and bands
are good to go I would look at the solenoids in the valve body. If you can find the Ford factory workshop manuals (I found a set for mine on eBay last summer for about $40) you will find step by step troubleshooting and testing on the electrical aspects. HTH |
