hey everybody. i have a problem with my trans, its a 01 gtp. one day the trans started to whine, the next it was occaisionaly slipping in 2 through 4. next it was all the gears. after that it was every stop. now it does this occaisionaly. i usually will have to restart the car every 4 miles (highway) also sometimes it will shift from 1st to 4th and lock up the torque converter. and at the time of all this happened the car started to hesitate and stumble. and still does that every other time. could this be a computer problem?? or is it definatly the trans?
