Just bought a 2005 Beetle Convertible GL w 138,000 miles for my wife. on 2005 Volkswagen Beetle

Car looks new and drives great except for an occasional "jerking" in the automatic shifting of lower gears. It doesn't happen every time but is noticeable when it does. There are no engine warning lights coming on. The other day I took it out for about a 30-35 minute drive in stop and start traffic and it did it 3 times. I'm just looking for some clues as to where to start trouble-shooting without tearing down the transmission.

No, I'm just going by the dashboard computer. Not sure how I would check the transmission specifically.

See if you can get it scanned at a parts store. that would really help. make ure to double check trany fluid. What does it look like.

Ok, I'll try to run a code but I purchased from a local dealer and they maintain that they checked the transmission fluid and saw now issues. They're willing to fix any issues but due to the nature of the problem; i.e. doesn't happen all the time, they don't seem exuberant to spend a lot of time with tests and diagnostics.

Try going to the parts store and ask for them to scan ur codes. Let me know what u get. If the dealer has looked at it and didnt come up with solution, Im at a deadend. If u can get me some code info, I can try for more help. gl
