First off........did you buy this Jetta new (10 year or 100,000 mile warranty on engine and transmission) Not sure if it covers the TCM or wiring, but it should cover the trans.


fuse, relay or ground maybe?
Does the dash indicator show the proper gear selection?

maybe cleaning up the wiring plugs after that voltage spike.
*** did you clear those codes?

I guess I might try driving the transmission with the valve body wiring disconnected to see if that would change shifting of the gears.

I scanned the computer on this 00 jetta 2.0 liter
and these are the codes that showed.
P0753A Shift Selonoid A Electrical
P0758D Shift Selonoid B Electrical
P0763D Shift Selonoid C Electrical
P0768D Shift Selonoid D Electrical
P0773 Shift Selonoid E Electrical
P0785 Shift Timing Selonoid Malfunction
P0748 Presure Control Selonoid A Electrical

Does anyone know what my problem could be? Do you think it is the
computer?
