A904 Woes.. not working right..

Killer6,
Not sure which damaged support you referring too? I'm asking which lever ratio I should use that will fit my specific need for this build.
I'm pretty sure I'm the reason the trans is smoked, and the clutches damaged due to heavy footed MORON driving and trying to chirp the wheels while in (D) instead of (1) :poke:
Whether the sprag alone(which appears intact/didn't get rolled) held, or if the low/rev band held the drum, it would have -0- bearing on smoking the clutch. The higher ratio lever only increases the clamping force on the band, it has nothing to do with clutch apply whatsoever.
And the kickdown/2nd gear band lever You are picturing won't do anything whatsoever in 1st/manual low, & the most common reason THAT band gets smoked is shifting @RPM from manual low, because the L/R band can't release fast enough before the KD/2nd band tries to grab the front drum. Even with an improved lever ratio, any overlap is won by the band that already has a grip on a motionless drum, that's the L/R band, so the kickdown band is always the loser.
The torn up alum. part is the "support", and if there's a lack of lube or improper assy./repair, it will be damaged, seals leak, pieces of debri clog fluid ports/passages, etc. The lever does -0- to address the damage I see, nor does it explain it.
