Exploding Torqueflight

I have had three occasions with a driveline failure in low gear.
Each time, the transmission came out & was inspected.
I only had damage on the transmission one time, if My son had made another pass, he would of had the same results of you.
Always start your burnouts in second gear, not first.
I run a blanket for safety on our current car. I will be using a shield on the other car we are putting together.
The 727's now have good aftermarket parts to prevent this.
The 904's still need help in this area.
