Got the transmission fluid changed, along with the pickup filter and gasket.... Still having the same hard shift from 1st to 2nd & it stays in higher gear after a drive and getting it up to speed. Sometimes at about 20-25 the engine would continue to rev with no pull from the transmission like it was in neutral. The check engine light came on and the gear lights on the cluster stayed surrounded by marks like it was in every gear, P,R,N,D,1.... Any advice for a repair would be greatly appreciated. Thank you in advance.
Btw. Drained out about 2 quarts that was brownish, maybe a bit milky looking, like water and oil. After leveling the car and filling it up, I got about 4 quarts in it after the warming up, changing the gears, and removing the plug until it just dripped. So it probably was low on fluid. Not a lot of metal or anything in the pan or on the magnets. Anyone think the valve body replacement is the fix?

More research, testing is in order; throwing parts at a problem without properly diagnosing the problem, can get very expensive and just end up with the same issues.


There are a number of possibilities on shifting issues; first step, would be scanning with a VW factory level scan tool and see, what trouble codes, live data reveal. Many problems can be external (wiring harness damage, failed sensors, shifter assembly broken, etc), then the typical sticking valve body solenoids or internal ribbon harness damage and worst case scenario, internal damage (hard/soft parts), problems, requiring a pull, disassembly to evaluate things, find the problem (full rebuild). Here is a video, showing the use of VCDS by Ross Tech; to read trouble codes and view live data:

Once, you get the diagnostic info and narrow down the problem; you can see, if you can fix it yourself and/or decide, if it is a cost effective repair, that may need a professional to address. Correct diagnosis, can bring clarity to the problem and help guide you, on what to do next. When, you move forward; keep us in loop, tell us what you find, what is revealed and we can go from there, thanks.

These two codes, relate to the transmission:

16997: TCM processor; no signal or communication.


I'm not seeing any documentation about specific testing performed and confirmation of the diagnosis stated in the repair eatimate. Electrical issues, are mentioned in the related trouble codes; testing and any actual proof of damage to the internals of the trans, would help with the overall evaluation and deciding what to do next. Unfortunately, many shops tend to err on the aide of "replacement", rather then confirm, troubleshoot and pinpoint the actual problem with the currently installed transmission. What they did to come up with this diagnosis and almost $3200 full trans replacement, is unclear.

Further testing and diagnosis; using a factory vw level scan tool like VCDS, would help intelligently, narrow down the problem.
