that's what a tq arm mounted to the tranny gets you... when you get the car back together, get a crossmember and get the TQ arm onto that please.... that will prevent this from ever happening again.

the trans was stock and starting to slip a little, I had already had plans to build the trans & remove the torque arm just haven't done it yet and this happened so I have to get it done know.

sounds like this only happens on the dyno. i wonder could it be the driveshaft angle being changed while it is on the dyno. makes want to invest in torque arm relocation kit and drive shaft safty loop.

A tq arm relocation crossmember, like the ones that BMR sells are hands down a part that should have been on the car from the factory, why they put the tq arm on the tranny case I will never understand, it is really a poor *** design, puts a ton of load on the tranny mount, etc.etc.
A driveshaft loop, also something the car really shoudl have from the factory IMO.
Definately get both, especially if you're making any kind of power or running at the track at all.
