Same here if you ever figure this out please let me know lol

[imdaman3]

(40mphgt) whats your car doin??

[40mphGT]

Well not all the time but if I take off slow as first then slowly lay into it it well jerk into gear and the higher I get into first gear, it will be jerky like I guess too best explain it. Buy 2nd 3rd 4th are all good. Its kinda wierd but it seems as if the valve body is sticking
