2001 Jetta auto transmission ( code P0730 )
 

I just bought the car and understood that the previous owner bought and had a shop replace many components (and a tranny). When I purchased the car (test drove) I didn't encounter any issues or lights. About 2 weeks later I was driving +70mph and the car revved up to about 5000 RPM's. After some research I found that this was a design by the car to do this when it encountered an unsafe mode (:cool: not sure what was unsafe). The "unsafe mode" feature kicks into 3rd, I think if driving in 3rd, 4th or Drive. If you are in 1st or 2nd it defaults to one of those two gears. I've personally found that I can pull over (shut down) - computer reset?? and take off again. That's some crazy **** that makes sense :eek:. Now I just want it fixed. There is a component under the drivers seat - think its the CPU or ECU or whatever. Its a black box, two screws and a wire connection. It may be bad or it may be good and just not synched with the transmission. Since my tranny was replaced, I'm assuming the backyard :confused: hillbillies that changed it missed that step to sync the computer that drives the tranny. It should be as easy as 1 hour of hooking up to mechanics (dealer), lubing up for the ass-reaming of your life.

I like my Jetta but damn these things are so female. If you've had this problem resolved in a previous experience then I'm all ears. Oh to get more info on the crap I mentioned above that relates to many of the other tranny issues on this site - just google "transmission safe mode" & enjoy.
