Well the car has been in the family for over 13 yrs all original. When my older brother started modding it, he had the same guy that did my last rebuild, rebuild the transmission with pretty much the same parts. They were upgraded parts and my brother dogged the hell out of the car when it was his and the transmission held up fine. Nothing was wrong with it when I bought it but I just wanted to rebuild it just so it will be new and he used the same parts. I don't know what happend lol. Just going to have to rebuild it again I guess. Going to put stiffer parts if I can. If you wanna play you gotta pay lol.
