MonteC's Transmission Corner (For Info Only)
I searched thru the thread and couldnt find anything that resembled my issue, so I thought I would ask.
I started having shifting issues on the way to and from my local VW club meeting. The truck shifts from 1 to 2 fine, but then it climbs upwards of 55 mph and 4k rpm before it will even attempt to shift into 3rd and after driving in 3 for a while the o/d light comes on and it will not even shift to 3. I was driving on the freeway with no way to get off at an exit when this first started happening and after about 20 seconds the trans temp light came on. When I got to the meeting I let the truck cool off for about an hour and a half, then attempted to drive it to the house, about 20 miles. I took the back roads this time, and until the trans got warmed up really well, about 10 miles, it shifted fine, but after that it would only shift from 1 to 2, and then the o/d light came on again.
I checked the codes like it suggested in other posts in this thread, and the only codes I get are ones for the o2 sensors, which is related to a plenum gasket issue that I already knew about. This is my wifes daily driver, so it has to be fixed asap so she can get to work.
Thanks in advance for any help anyone is able to offer with my issues.

Been reading up about removing the OD unit and replacing the snap ring. I'm not sure I want to tackle the actual snap ring replacement and might consider removing it and taking it to a shop. I see it talks about having an alignment tool to keep the splines aligned. If I don't have this alignment tool, how easy is it to knock the splines out of alignment.? Could I take the chance and do it without it if I am careful? Or do you not recommend doing it without the tool?
Hey, heyyou or monte, what's the gm sensor solenoid supposed to do exactly? Is it for extending trans life or improving shifts/driveability? My trans was rebuilt about 15k miles ago. Shifts well enough, but does not like to come out of lockup unless you really lay into the throttle. Will also jump from 2nd to 1st at partial throttle (a bit too sensitive). Tv cable is adjusted per factory specs, thinking the gps may need changing anyway, since its the original with 147k miles (was not replaced when trans rebuilt). Will this conversion help at all with that? Sorry to butt in, but thanks.
BTW you better change the TPS instead of your GPS.
I will pull the pan asap and post pics of what I find.
Thanks again for your help with this issue MonteC.

I checked earlier yesterday to make sure all the lines were on and that the fluid level was correct, then took it for a test drive. It shifted fine until it got heated up, then would only shift from 1 to 2 again, unless you took 2 up to around 45-50 mph and then let off the accelerator, at which point it may or may not shift for you, probably shifted half of the time. Does this still sound like a rebuild candidate, or does it sound like the governor solenoid?

Pulled the pan today and there were only small copper colored flakes in it, but the filter was clogged up something horrible. I went ahead and cleaned the solenoid , the top half of the screen was covered in gunk also, while I had the pan off. I also spoke with a couple of local shops around town and they said that if the shavings in the pan were brass/copper colored, then torque converter has probably bitten the dust and needs to be replaced, so I am going to go ahead and drop the trans and torque converter this afternoon.
Is there anything I can check to verify that the torque converter actually is the issue, and that the trans doesn't need a rebuild?

your 2nd gear is toast. by disconnecting the tv cable is only letting the trans shift out of overdrive and into 3rd gear. when it properly downshifts it downshifts into 2nd then back up to 3rd then to overdrive. you sir need a rebuild.

Pulled my oil pan and lo and behold, the issue would be that I have spun 7 and 8 rod bearings, so its no wonder the damn truck wont go anywhere, LOL.
I appreciate everyone's help and patience with the transmission newbie.
