my 2000 jetta has a P0730 error code does this mean the transmission needs to be replaced?
P0730 code on 2000 Volkswagen Jetta
p0730 incorrect gear ratio means the rpm going into the trans dod not match the rpm output for the gear it was in at that time. if you have symptoms Valleyautotech is right on. i have seen this as a ghost code on some audi's. if you wind up replacing the trans, make sure they flush the cooler.
Double check the trans fluid level and if its full then this means that the transmission is slipping. Time for a rebuilt transmission
