2004.5 cummins tranny trouble
Got a 2004.5 2500 cummins having problem with it shifting, when starting from stop and mashing the throttle it will redline before shifting into 2nd until let of throttle then shifts into other gears fine. If easying into throttle at start it will shift through the gears fine and when stoping it will shift hard into 1st at times. Running a TST programmer and tranny was rebuilt roughly 3 years ago. Anyone have any ideas what it might be before i take it in.
