ok, this is starting to make more sense, you are NOT running the corvette servo. i have vette servo and transgo spring arrangement in my truck and it is not agressive. I bought a rebuild kit which came with a drilled separator plate from dana 10+ years ago. now that I am more fussy I would make the 1-2 feed orifice smaller, i think it was in the 0.076" range but I have lost all my notes when i built it.
I had previously ordered the TransGo SK - 4L60E shift kit in the orange/black box (blue box is same) and the 7CS but unsure if I should use the springs. Pump has the 700-PKH.
And I bought the Sonnax pinless accumulator pistons individually early last year, even before the SK, maybe even before I had found a core 4L60E to build, because they were about the same price as the regular aluminum pistons after discounts....
I tapped the 4th with a 1/16th NPT and plugged it w/a couple drops of hi-heat Loctite red #263...
I have both the GM '07 separator plate as well as a bonded separator plate with built-in screens, I thing the one that ends in 782...
I see Cline made a recommendation affected by which band too--I'm using the Sonnax WIDE band and brand new TY GM rev-input drum...if it matters.
