Hi. I have a Diablosport handheld tuner with a custom e-mail tune,similar to blackbear?...My transmission sometimes shift really hard,but it doesn"t do it until the tune has been in the vehicle for a few days....will resetting the TAPS at my allison dealer fix this? My tuner said he didn"t touch the tranny settings...I've done intake modifications that heav yielded 2 mpg better mileage and better throttle response,I wanted to put a semi-mild Raylar cam in it,but not if my tranny is acting up....deep pan,transynd,and full flush doe 25,000 miles ago. Thanks!
