Drilling low reverse clutch

[PaulRV6]

I'm thinking about drilling a hole in the base of the LR clutch. Is this worth the hole in my new part? Do I need a special drill bit to get thru this hardened part? I just wonder if it affects the apply rate of the fluid and if there is any downsides for doing this? I'm assuming it is at the floor of the clutch in the corner so it doesn't affect the sealing surface? Thanks for your opinions and helping me make a decision.

And to ask deeper, where was this drilling advice obtained? I've not read that anywhere. Are you talking about the direct drum?

Bet he has a CK manuel, it is in there.

It was for the low/reverse clutch housing a .060" hole and recommended by one of the valued members in the manual. Just wanted to get more details specific to the drilling.

Steve, you are correct. It is worth anything?

Chris says it softens the apply of LR clutch. It is your call.

.060 seems like a massive leak to me. At 200 psi, a hole that size flows just under one gallon per minute; .96.

Don't know, never read it.

OP, Adding any hydraulic leak in a 200-4R is a real bad idea. If you need the low reverse to come off quickly, use 2 springs. Stack 2 steel, 2 clutches.
