Okay before i thought my tranny was blown because i would put it in drive and it would feel like the car jumped then it would shift in to 2nd or any other gear in less it was in the 4grand range so today i drove it for a while kind of driving hard but not really then all the sudden it started to shift normal all by it self so i go to put gas and drive it just barley slips sometimes does anybody know what is wrong was there a clogged valve or something oh and before it shifted well i was on a straight away and went about 70-80 mph and took a turn and it shifted normal.
