at 30 mph something weird happens my tranny slips into what i would call not all the way in gear but when i step on it it operates like it should i went to the shop that put my new tranny in and they did the pressure checks and every thing is great.he said that the throttle sensor associated with the shifting speeds might need to be reformatted(not exactly what he said but close).anybody had this done?

APPS sensor calibration is here... http://mopar.mopar1973man.com/cummins/2ndgen24v/apps/apps.htm
