I have a 2002 Jetta GLS 2.0 with an 01M transmission. I am hoping someone might be able to read through my symptoms and suggest the next step in diagnosing and solving my problem.
For a couple of years I had issues with my reverse gear. It didn't seem to fully engage most of the time. If I gave the car gas it would slowly start to reverse, but did not feel like it was working properly. Sometimes, while slowly reversing I could feel it pop into gear, and then the car would reverse as normal.
Since then, my reverse gear has gotten worse. It will show the same symptom of not feeling like it is fully engaged, but in order to get it to engage you need to shift to another gear and then back into reverse.
Also, at some point I realized that at higher speeds (~80MPH) my speedometer goes haywire. The pointer oscillates around the speed range I'm at, and will begin to work again once I slow down (below 75ish).
Latest symptom is that the car will not be in Drive unless I give it a little gas. If I stop at a stop light, and then let off the brake, I will not roll. I have to give the car some gas and it slams into 1st gear.
Environment temperature or vehicle temperature do not seem to have a factor in the symptoms. Sometimes I can get reverse to work as soon as I start up the car in the morning, sometimes it takes 5 minutes to get it to engage. However, Reverse works less than 50% of the time. The latest symptom with drive seems to occur more and more often. If the car rolls when I let off the brake at a stop, I am surprised.
If anyone could give me some information, or guide me towards a source of information, I would be extremely grateful.
I appreciate any and all help in advance.
P.S. I don't know if it would be helpful, but I may have access to a local Vagcom. I don't think I would know exactly what I'm looking for considering there are no CELs.
