Tongiht i was driving my car havent been drivng it much since gas is 2.40 a gallon. Any ways i went to pull out on my street and i noticed my speedo was at 0MPH then it jumped up to 25 which was abot the speed i was going. Then i got on the freeway and the car didnt feelright at about 80 it was bucking back and forth. then i got off the freeway and the car was at 2000 RPM in overdrive when it is normaly around 1500. I did a filter change back in january. ITs a 91 Camaro V6 with a 700R4 The tranny has been rebuilt 3 times so far last 3 times the clutches cracked and it wouldnt go into 3rd or 4th It was rebuilt back in 2000 has about 40,000 miles on it since the last rebuild. But never had a prolem like this before. Any ideas what it could be Im broke so cheap fixes would be nice i dont wana get my tranny rebuilt for a 4th time.
