If you have your foot on brake and slide it in and out of gear..it doesn't jump.. so no...unless the torque converter is locking or your TCC solenoid is only locking for a second..but that'* not typical.

..anyone else have any ideas?

Judging by the pics he just sent me, he has a torn CV boot and his CV joint is shot. Green goo everywhere.

My car did the same thing about a month ago, but ironic as it is, this morning, while on the off-ramp , I was coasting, and when traffic cleared, I stepped on the gas, and my tranny acted as though I was in neutral, and then slipped back in gear. I can't help but think it'* related to the jumping thing we're discussing here.

Any advice would be very much appreciated. I hope I don't need a tranny, That would make me mad as heck. I can barely afford gas these days..

edit: I wanted to add that this off-ramp was a huge circle. Maybe that played a role?

Get it scanned, or check your fluid. Consider a flush. Slipping is a whole different ballgame.

Sam...my understanding of the posters problem is sitting at a stop w/foot on brake and the car surged or jumped forward. A slipping transmission would seem unrelated. Please start another thread, check tranny fluid level.

I was doing a routine check on fluids a week ago, and my tranny fluid looked fine, but I'll check it again today, to be sure it'* up to par.

see the edit in my last post... Not sure if that makes a difference.

Based on that, I'm going to assume my issue today isn't related to the problem I had which is similar to the poster'*

I'll check my fluid again. I think I'm probably due for a new tranny filter, so this would be a good time to get that done...
