Heres another word of caution. If you ever have a driveline failure while in first gear, always remove the transmission for inspection of the overrunning clutch. If this fails, it will go KaBoom the next time you race it.
Last season, I broke a u-joint on leaving. Removed & dissasembled the transmission. Got lucky no damage done.
First race out this season, broke a ring & pinion while leaving.
Damage so far, ring & pinion, overrunning clutch, & convertor snout.
That was a good hit to the race budget at the start of the season.
I know its a hassel to remove the trans, but it might save your feet later on.
I will be installing a trans blanket back on the car this time, just for sucurity.
