Performance 4EAT

[presslab]

I've got my 4EAT trans apart and I'm about to order some parts to rebuild it. Does anyone have recommendations? I've done the TCU mods to increase cruising line pressure, a shift kit, and a high stall torque converter. I put that into a JDM trans with low miles and the high clutch is shot a year later.

It looks like maybe Alto offers a 1.75" carbonite band, and they have some high energy frictions. What does it take to fit another friction/steel in the high clutch? Some machining I guess, and a different pressure plate.

Anyway, any pointers would be great.
