Hey hey,
I'm new to this forum and I couldn't help but see this problem is very, very similar to a baffling problem I had with my 99 Contour SE 2.0 DOHC
Now, my transmission fluid started smelling burnt, apparently the 2/3 snap ring wanted to depart from this horrible, horrible life. Since I loved the car so much, I had the transmission rebuilt at a local shop and while they tore it down I had them install a tranny cooler too.
I was ecstatic when I got the car back, but I got a horrific series of bang shifts, almost like the transmission couldn't decide what gear it wanted to be in. If I pressed it enough, it levelled out once the engine got up to temperature, and it was also fine if the engine was cold. The transition with heat and cold seemed to do it, and driving the car anyplace was like a scary bucking bronco.
The tranny shop was baffled, they tore the whole thing down again, tested every nuance, etc etc, and it was completely fine. I was back and forth with them for about a month with this. No engine codes, no tranny codes, nothing.
I was almost ready to give up on the car, but since I figured it was a computer problem, I decided to start having random sensors that were related to the transmission changed. No go with any speed sensors or whatnot, and then I saw an odd sensor that looked like it was directly on top of the transmission, so I asked what it was. The shop replied that it was the Manual Lever Position Sensor, but it was fine because it wasn't shooting a code, and that they even tested it. When I found out it was 50 bucks, I told them to replace it anyway, and I never had the problem again.
Now I was a bit shocked at this, so I pulled the specs for the MLPS and started testing the old one with a multimeter, because I'm more of a geek head than a greasemonkey. Now it's been about two years since all this happened, but I basically found out that the thing went just out of whack enough to mess with my head but not out of spec enough for the car's computer to realize that it was failing, thus no code.
Anyway, the part number is 6L8Z-7F293-AA and I found pictures of it it on ebay item number 330234092868. Can't seem to find it in autozone or any other place like that. I'd replace it even if it's not throwing a code.
