i have a 98 12v with a haisley street puller clutch and billet input shaft, i've had the clutch for a year now no problems and have never towed or pulled. last night the clutch began sticking. i came up to a light had it in 2nd gear went to take off and the truck jumped foward and stalled. i was unable to to get the truck out of gear while the engine was running and when i had the pedal pushed all the way down it still wanted to take off. i had to shut the truck off and hit the pedal real fast to get it to come back up then it would drive fine. there is nothing wrong with the pedal it works fine i'm thinking it's the hydraulics anyone have any ideas
