Hey all, I think I know we're this is going but I'll ask anyway just to be sure. I'm having some bad problems with my auto exec. The gearbox is having MAJOR Problems....when I select drive the trans doesn't go in drive. I give it a little throttle and. It slams and I mean SLAMS into drive. But once car gets going it cycles through 1,2,3,4 and reverse fine. The problem seems to go once the car is fully warmed up. The fluid is full as well.

Input/output sensors?

Hmmm...maybe . I might take a look at the selector lever and see if it needs adjustment. But with the way it slams into drive and how it stops when the car is warmed up makes me think it's the internals of gearbox. �
