Allison 5sp: Transmission Autopsy after 1100+hp

[TrentNell]

Pulled the trans today to send the converter off to be tightened up a bit and checked out ,took some pics and was pleasantly surprised with what was found ! there was not alof of passes on it so far , probably 15 passes and 10-15 WOT street runs that were equal to 1/4 mile passes . A big thanks to Mike for a setup that is working at these power levels and also sent you a PM with some more info , most said it couldn't be done , The truck will be back together for the Dougless WY race and the power may even be turned up a bit more , if money allows a bigger secondary ( PBK ) will be going on also but doubt it will happen as thats a big chunk of coin with out selling my S510

the clutch pics are in order c-1 - c-5 and snapped pics off all the planets they are not showing any signs of twisting so far ! here's the pics ......................

As of this point all the hard parts are stock but at 5500 lbs it def helps , money pending a billet output might find its way in this time down , would like a billet c2 hub also but doubt i will be able to swing it at this point , i wont replace the input unless it breaks .

 

[duratothemax]

try that on stock dodge/ford trans hard parts.

 

[THEFERMANATOR]

Are those the new GMAX style C3's and C4's?

Trent, your truck is badass. Thanks for proving me wrong about the ally lasting at those power levels.

Thanks for posting.

There is still a ways to go , but so far it looks promising

I'm impressed with how things look. I would have to imagine the weight of your truck will allow the hard parts to last slightly longer than in a DD. Anything can happen at your power level though. Good Luck!!
