some folks have drove a while with this condition. i hear there is something that strips out inside the trans that has to do with fourth gear. thats what our overdrives are is 4th gear and a tcc lock up. unfortunatly there are some folks who get this condition and know that the trans is on its way out. i had my first hand experience it took me o a month to kill the trans lol i got the car with no 4th gear so who knows how long it drove b4 i did the damage. do some research on this site and there is some info on replacing this bad piece and making the trans work right. its not easy. i hear it can be done in the car. just start to prepare yourself and maybe look for a used trans or even a rebuilt one. as most people know the "triple edge performance" advantage stands out on this site and on the reliability and durability. keep us updated.
