While the Allison is suitable for stock applications, we’ve found that it does have its limitations— particularly when flywheel horsepower exceeds 370 horsepower. That’s when the stock clutch packs can begin to slip, putting the computer in the dreaded “limp home” mode and once a clutch has slipped, the next time it will slip easier and easier.
