Alright here's the story. Approx 2months ago I started getting the flashing arrow all the time and it had all the classic symptoms of a failing PNP. So I lived with it and then I had to leave for 7weeks (Air Force) well, when I got back I figured I should order a new PNP switch, which I did, all the while it kept getting worse and worse, to the point where it wouldn't shift from first in Drive (I'd have to keep it in 3) or it would go into limp mode. Anyways, I only drove it like that for ~week, no other problems, it still shifted fine and what not, then a couple of days after I ordered the part I'm driving to a friends house and I stop at a stop sign. I start going again but then at about 10-15mph (~2500rpms) it just slipped into neutral and kept revving when I gave it gas, but no go. So I pull over and turn the car off thinking it's the PNP. I do the ratchet thing a bit and try again, nothing won't go into any gear, the car revs up a little bit like it's about to engage, but never does. So I call my dad to pull me home, while he's on his way I let it cool down a bit, and I was able to get the car goin again but same thing, at ~10mph it just slipped into neutral and once I stopped nothin. These were the codes given. Also I had put in an S70 instrument cluster and the speed was erratic so that is the 232 code

232 Speedometer signal missing
313 Faulty signal from gear position sensor (PNP)
322 Incorrect gear ratio

Finally the PNP switch came in, and I installed it (easier than I thought it would be) and went for the test drive, and it went a good 2miles and was shifting as normal but then as teh car warmed up, it started slipping again, and eventually wouldn't engage any gear. So this time I experimented a little. These were the codes given (I cleared them just before driving)

232 Speedometer signal missing
322 Incorrect gear ratio

And it wouldn't go back into a gear, but then I tried resetting the TCU everytime it died, and it would engage the gear again everytime, but it would still slip back to neutral at 10mph. These were the codes that were consistent after this

232 Speedometer signal missing
322 Incorrect gear ratio

So then I decided to put the old cluster back in to see if it would fix the speed signal problem, which it appears it did , and it drove fine when cold, shifted fine and didn't appear to be slipping but then as the car warmed up the arrow started flashing and it slipped to neutral and I got these codes

313 Faulty signal from gear position sensor (PNP)
322 Incorrect gear ratio

So I reset it so I could coast home and the 322 code came on as soon as I started the car.

So to sum it all up, what!?! Could it be the PNP switch is just not aligned right (I aligned it as best I could according to where it was before, but it was a little dark so it might be off. What is the error of margin for this alignment and could this be the reason. I mean I don't mind drivin the 740 but the 850 is ALOT better. Also how much is that alignment tool? I still don't think it's a mechanical problem as it works perfectly fine (albeit for a short time) when the car is cold or the codes are freshly reset.

Any insight would be GREATLY appreciate, Cause I don't have the time or money right now to replace the transmission.
