So I have owned my 02 SE for about 5 years now. Never had any problems with anything other than a front strut I broke due to a bad pothole. I jumped in my car the other day to run some errands at lunch and it started behaving strangely. IE. lurching and droping out of gear. I had no prior issues with it, no indications, anything that I could tell. So the following week I was going to take it in and see what was up at my local dealer. Well I made it to sunday with no other issues. I got in the car put it in reverse and it wasnt there. I had nothing. iIt was like being in neutral except it wouldnt even roll backwards. So I called a tow truck and the idiot couldnt get it out of the parking spot due to other cars and whatnot. He had no jack with him and the car wouldnt roll backward. After about an hour of he reving the engine and monkeying around with it to my dismay he finally had 3 cars move and was able to get in behind and tow it. I took it to the dealer who informed me it was "an internal problem with the transmission and I needed a whole new one at the price of $4k" Not knowing a lot about cars, but knowing enough to know that seemed high I asked if it still drove in forward and was it safe to drive it home. They informed me iit still worked in forward and I could pick it up anytime. So I attempted to drive it home and got about 3 miles. At this point I could definately tell there was something seriously wrong. Lots of grinding, slipping, etc. Needless to say another tow bill later I had my car home. now with no reverse OR drive. I called around and got some estimates on a rebuild. I chose one of the bigger names around and decided I was better off with a warranty than some cheap shady mechanic. two days later I get a call from the shop and I am told that the internal gears "have welded themselves together"

So now I am in the market for a new one and the shop is having issues finding one. So I need some info as I'm trying to save myself some money on it.
Does anyone know if the U140F transmission was the only one for the 02 V6?
I have found some low milage used ones for cheap, but they dont list model numbers. If that is the only transmission for 02 V6s I'de be more comfy knowing those are an option without a part number.
Next question is what other models/years use the U140F tranny?
Thanks in advance!
