It's has a 3 speed Chrysler trans. That day the trans brake was not working so he was just foot braking it tell he felt the car move and let it go. The last pass (5.40 at 128mph) the line lock stuck on, it was dragging all the way down the track, when he slowed in the shut down area the locked up. That's why the mph was down. When they get a handle on it that car will run in the 4's at the 1/8th
