I have a 2000 blazer zr2. I am installing the trans go sk 4l60e L shift kit. In the process of drilling the separator plate, I made the mistake of drilling the fwd clutch accumulator feed hole to .093 . My question is will this slight size increases negatively affect the trans shift?

Note.
I am also installing a sonnax pinless fwd accumulator piston. I don't know if this will make a difference with in my mistake, but i thought I might throw that out there.

 

Bring it down to .086" (factory setting) by putting the separator plate on a steel bock and use a steel .250" checkball and place it on the hole and 2-3 whacks should bring it down easily. With a .093" hole and a stock TC could make for a firm neutral to forward gear engagement. I use .086" forward clutch feed hole in everything that I build with no complaints, with either the Sonnax pinless or the aluminum piston with hardened pin.

 

Right on. As of right now its not doing too bad, but I can definitely feel the firm grab when I put it in drive.
I actually have to get back Into the vb and change out the 1st/2nd accumulator bushing spring to the next heavier one in the kit, because it takes a little longer than what I would like between 1st and 2nd. So i will apply that fix to the feed hole as you said when I Chang that spring.
Thankyou for your help sir its greatly appreciated.

 

What 2nd servo piston are you running? 4.3L S/T trucks generally have a harsh 1-2......Is this a new 2-4 band?

 

Clinebarger why is that anyways?

My blazer w/4.3 versus my s10 w/LQ4 shift a lot different

 

My 04 Astro does sometimes shifts pretty hard.
It's got 139k on it tho so that may have something to do about it!

 

That's a great way to do it!
No substitute for experience!!!!

 

It's a combination of things.....Higher shift point, Large Ratio Accumulator Valve (DX), Loose Band Clearance, To big of a 2nd feed hole, & a Tight Converter.
