i purchased a 2001 vw beetle 1.8L turbo automatic transmission with 130K miles from a family member. Since we bought the vehicle it has had some major transmission problems from which we cannot seem to fix permanently. It shifts hard from 2nd into 3rd almost to the point where it does bark the tires sometimes lol. i have taken the car to the local vw dealership 4 times. fixed all the codes that kept coming up which were. a temp sensor in the main engine compartment and 2 oxygen sensors underneath the car next to the oil pan. The hard shift tended to lighten up a little to where it was not as bad as before. now it tends to skip 2nd and 3rd and stay in a high gear until you turn the car off or manual switch to 1st gear. sometimes it evens shifts fine through 1 2 and 3rd but fails to shift into 4th at around 55 mph the rpms are at around 6k. i do not have much money and going to the dealership seems to not be helping at all. can someone please help this poor girl out! thank you so much. My Dad seems to think its a ECM problem because of being able to turn the car off and that sometimes fixes the problem till you decide to turn it off then back on. clearing codes seems to help also. very weird problem. any help at all is very appreciated. sorry for my lack of car knowledge!

I have a hard time believing a rebuilt valve body for $100; would be of good quality or last. Most we see on this site, that have worked well for people; fully rebuilt, tested and with a substantial warranty seem to be in the $500-$1k range, depending on which trans you have 01M 4 speed, 09G six speed, etc.
What is wrong with your car and which tranmission do you have? What year and model is it?

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:
VCDS® HEX-V2® Enthusiast
- USB Interface -
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.
