Next run I went out and was doing great through the 1000 ft. A modest 1.54 60 ft with an 1/8th mile of 7.14 at 98.5 mph a whole tenth faster then the run before. But when I went to shift into 4th I blew the trans and coasted to a 11.4 at 103 mph. I was warned that the trans would wear faster from power shifting, but I had know idea that it was going to go that quick. I got the car towed up to JPC ($260) where it was confirmed that it was the transmissions 10 spline imput shaft that went. The car will now get a 26 spline and 4.10s will go in while its there as well. FYI: It was the stock trans.
