Re: P0734

Welcome to the garage Rob.
The P0734 code could be something serious. It means incorrect gear ratio for 4th gear. The TCM monitors input and output speed and when this is not in a certain range for a certain gear, then you get a message like this. That is normally a slipping clutch, or somerhing wrong with one of the speed sensors.
How does the transmission behave, do you feel that it is slipping?
