the tranny seems like its slipping. It ran fine for a few drives but then started acting up after my madz28 tune. If I put it into 2nd and rev going around 20 it acts like its just in neutral until I stomp on it and then it moves. Same in first it stays in first for along time. Wont shift unless I get on it or reduce the pedal. What could be wrong? Any ideas?

Did you have the line pressure raised? Sounds like it's time for a rebuild...

 

i think i did. but the tranny has been strong and it all of a sudden went?

 

PLEASE post on the correct forum. Questions about a "tranny" don't belong on LT1 Engine Tech". This is the second post of yours I've had to move today.
