the other day i pulled outta work a lil slow and nailed it at about 10mph, just so i wouldnt break traction. it shifted into second fine but got into drive and revd up with no power. its done it once before. the trans was rebuilt about a year ago and id like to go in there and adjust the bands and turn up the line pressure a bit. im only brave enough to do this cause ive heard its done by only removing the pan. can someone give me some insight into how to do this?
its a A518 trans BTW

Adjusting bands and pressure will not fix it.

Almost sounds like a hi/rev drum seal. how is reverse?
