Broke my trans tonight

Ran down the track a couple good times tonight and on the 3rd run broke something really bad in the trans made a bunch of noise the engine reved and stalled now the motor won't even crank so i guessing the chain or input shaft broke and is stopping the motor from turning over but at least i had fun in the process had 2 good runs. Anyone got any ideas on what i broke??

(( So i will break the old diamond back and get some exercise Until im up and running again Hate hearing about another broken one. :/ At least yours went while you were having fun.
My good friend and 30 year GM Master Tech Trans specialist will be offering builds. He has built a half dozen trans for my various personal projects and they perform awesome! He built the 4t65e in my Turbo GXP (LS4) and it's a beast. The plan was to build a trans for 08 Pimpala and let him report an independent evaluation - looks like the time table got bumped up after we met at the track last night...
08 Pimpala was running really well till the
The unusual cold weather in FL conspired to deny my GXP traction, so I'll see what we can get done after it warms up.Far as the trans offering, they'll be less expensive and much faster than Triple Edge Performance (TEP). Nothing against TEP - Dave and his crew do great work, it's just a PITA to wait 6-8 weeks for a trans when the stock one gives up the ghost and you need your car... I'll start a thread when it's all set up.
Lol But atleast i was fortunate to already have one in the process of a build so should only be another 2 weeks or so until im driving again and with all the goodies im putting inside the trans she should'nt ever have a problem again
Hoping to get 08Pimpala
back on the road soon... After that the hope is to have all the parts on hand so turn around time is minimal - nothing worse then breaking your ride and having to sit on your thumb waiting for parts! The last real hurdle is setting up affordable shipping... anyone able to weigh in?
