thunk off the line

[chrisLB]

ok my tranny shifts good no problems other then when its warm if i punch it off the line nothing for a sec then thunks and takes off.. if i drive normal off the line no probems.. the fluid level is fine and its always done it for the day i got it 2 years ago.. was wondering if thats a pressure control problem?

Sounds like a PCS issue. Hows the fluid? Any metallic flakes, smell burnt? So motor revs then finally violently engages 1st?

That's what it does.. Revs then bang lol
No flakes and the fluid is still a nice red..

PCS I'd bet. Take it to a shop and have them check your line pressure under heavy and light throttle
