2001 Volkswagen Jetta RPM at highway speed

Not sure. I can tell you that we are bringing it back to the company that rebuilt it. I counted the shifts and it adds up to 4. 1, 2, 3, D. According to the spec sheets I found on that model it should have automatic overdrive. That would add up to 5. BTW sorry about the mention of 4WD. It is a front wheel drive. I am fairly certain that it is not shifting to O/D. I am just not very familiar with V/W. So I am looking for info to help build my case!

I just wanted to take a minute and thank you for your help. We took the car to another reputable franchise store because the damn thing stopped working all together. Turns out the first reputable franchise basically ripped us off. Not only did they not "rebuild" the transmission it was the wrong one for that car. That year Jetta is supposed to have a five speed auto and it had a 4 speed. That would explain why the RPM's were so high. The only good news here is they are not charging us for replacing it (They are billing number one). I will be contacting their corparate offices to sing praise for number 2 and slamming number one.
Hopefully I can recover some of the other expenses.

Thanks again!
