4l65 1-2 shift

Recommended Posts

hi guys.. have a question... 2004 sierra denali 6.0 awd...when my trucks shifts from 1-2....right after the shift i can feel a double or triple bump or studder.. in fast succesion....somtimes if you hit the throttle just in time right when it shifts you can kinda mask it.... it is more noticable under light to moderate throttle or when under load... under wot throttle it seems to shift fine... the truck has a tune in it.. but the condition was there before the tune .... could this be the trans slipping?....
