Drum explosion...

Very good points, 496dart. However, a bolt-in sprag won't prevent an explosion. We like to upgrade to the 16 element bolt in sprag for better holding power/sprag protection over the 12 element sprag.

Along with the low band apply valve body, I'd highly recommend a billet from drum that is capable of freewheeling 15,000+ rpm. It's the drum that over-revs and explodes (stock drum explodes around 9000 rpm) when the sprag fails. Keep in mind that's transmission gear-train RPM (engine rpm x gear ratio).

Like was mentioned, it's a tough transmission and works very well with good components/build techniques.
