i tore the thrust washer on the crank a new sphincter in my 400 sbc. I sent the torque convertor back and had the 700 checked out and everything was fine. this damage happened after only 1k miles and I obviously don't want it to happen again. I could find nothing else wrong with the the motor, but the detent cable had to be modified because I had a bent linkage on my rottenchester quadrajunk. Just wondering if this is possible or what else it could be. thanks for responding. Brian IT'S A 1 TON THING.... IF I HAVE TO EXPLAIN IT, YOU WOULDN'T UNDERSTAND!!!
