P0734 is rare. If you had a slipping C2 clutch ( 4th gear ) it would most likely throw P0776 or P0777, or P0735. The fact that it is jumping out of gear indicates that the turbine speed sensor and output speed sensor numbers are not jiving as far as the TCM is concerned and it will throw the Alli out of gear. I'm betting output speed sensor in ...After shifting back and forth a bit, started getting kind of gear gnash noise when selector was put in any forward gear.
