How Long will Allison Last with Stock Engine Before Needing Rebuild?

I've seen posts with blown Allison trannies, but so far all the ones I have seen were with engines which were modified. How long will a stock Allison go with a stock Duramax engine? Is there some sort of estimated lifetime?

I know several bone stock Duramax Diesels well over 300K. Still on original drive train components.

Pretty impressive in my opinion....

Who could drive that long with a stock vehicle though

No seriously though. They can go a long time like anything else if they are well maintained

Stock is reliable.

I have seen them go over 500k on an lb7. But 300k is EASY on a STOCK motor. NO POWER ADDERS.

I've got 289,000 on my stock tranny. No problems. And I've got a tuner
