Default blew the 4L60E
The girlfriend and i were heading home on the highway in her 94 Chevy 1500(w. 38in superswampers) and we gave it a little gas to pull around someone and all of a sudden the truck went BOOM! we pulled off to the side of the highway and we could not get the truck to move in any gear...fun day

I started to tear into it and this is what i found...

(input clutch drum) overrun clutch piston cracked






This common on lifted trucks with large tires on stock trans?
