That it shifts and is quiet while sitting there running, says to me that the input probably broke clean, or the clutch came apart.

I'm assuming that you DON'T have the stock dual mass clutch in it anymore?

Mark.

Nope... Spec “ST” which has been a great clutch. It currently has 70k of abuse on it. It’s supposed to be good for 2500lb/ft and in perfect conditions I might be at half that at best. It’s a solid hub (non-sprung) so not incredibly quiet but has been rock solid since 2007. Odd thing though it works best with stock hydros; I have a set of southbend HD’s but the throw was all wrong so when the last new tranny went in I put a new set of mopar hydros in and all was well again. I did have to replace the pilot bearing once however but beyond that no issues.

All that said if the clutch is fragged I will be installing something a little lighter duty. Clutches are cheap... G56 parts not so much....

Bearing retainer? Transmission case that holds the input shaft I assume? Not the pilot bearing on the flywheel; right? I plan on replacing the pilot either way. Cheap insurance. I’ll have to look at the input shaft case bearing.
