Rebuilt 904. Whirring. Dead?

Sorry to dig up my old thread, but for those who are interested the cause of the problem was found.

I took the trans to a reputable trans builder who specializes in building tuff-as-nails 904's.

He had it apart in minutes and it was discovered that the output shaft used was a slant-six one and had been fitted into a V8 planetary gear set.

Admittedly an easy mistake to make as they are nearly identical aside from the pitch of the teeth on the end, however also a costly one.

The slant six output shaft and brand new steel planetary has been partially sheared and sent fragments of steel around the entire trans and converter which are now being cleaned out and reconditioned.

Luckily there is only very minor scuffing to the planetary set and it will be salvageable and still stronger than an alloy one.

The Slant six and V8 output shaft look remarkably similar.

I hope this might help would-be trans builders take note to avoid making the same costly mistake that was made on my trans!

Cheers, Frosty.
