Yes, Trans-Go is referring to the 2nd Apply Piston - disregard any other info in the attached image (instructions are for Corvette Servo modifications).
I guess the reason I’m not going with a corvette servo is because I hear some horror stories about it damaging things. Also if it does not work out then isn’t impossible to change back out while the transmission is in the car
I’m not going with a corvette servo. Are you referring to the hole drilling for the corvette servo
The original question was, which piston your instruction sheet was referring to - the one in the servo? The answer is yes. It's referring to the 2nd Apply Piston.
The image I posted confirms that your instructions are referring to the casting numbers that are on the 2nd Apply Piston (which is part of the servo - not the 2nd Accumulator Piston). Do not follow the instructions that I posted. The arrow is for reference only. Sorry for the confusion. Follow your instruction sheet.
So, look at your 2nd Apply Piston. If it has the "093" or "95-1" casing number on it, enlarge the holes in the plate per your instructions. If it doesn't have either of those two casing numbers, don't enlarge the holes. Don't assume that you don't have a Corvette servo. The Corvette servo is probably the most common mod everyone does to these transmissions.
Well I tried to pop my servo back out to check the casting numbers and I am having one Hell of a time getting the cover out. It’s not the new blue o ring I previously installed because the cover is spinning around freely. It seems the aluminum surfaces are stuck together real good. I’m probably going to mangle the **** out of the sealing rings. Can please anyone chime in on how to pull a servo cover back out. Damn road blocks everywhere I turn😤. I hate having to wait for parts and the auto store don’t have crap
By looking at your picture you sent previously it look like the cover is stuck to the 4th piston. This transmission is causing me serious psychological harm😡. How do people do this for a living???
What’s the technical reasoning behind the hole drilling could I just compare the hole diameters between my old separator plate And the new separator plate. You mentioned before that I should not assume that I don’t have a corvette servo. My transmission is bone stock. I just don’t like installing and removing parts over and over along with the possibility that I will damage them. For gods sake you can’t even get a freakin o-ring without waiting a week for it online. Boy did I learn a lesson from all of this, pay very very very close attention when taking these mechanical nightmares apart.
Well I went back and pulled the servo out. I had to mangle the outer blue ring and I had to pull the pump back out because the endplay was about 0.030. I got a couple of days while I’m waiting for a thinner selective washer and new pump gasket because I already torqued it down. Here is a pic of my casting of my 2nd apply piston
