How many washers to put in the TransGo setup?
I want crisper shifts at partial throttle, but not too hard because it's my daily driver. But at WOT, I want more neck-snapping shifts. (As long as it's still healthy for the tranny).
How many washers are you guys running in your kits and how do you like it?
As far as the tranny lasting with 3 washers, mine has been through hell and back and it's still hanging in.
I also blocked the fourth accumulator feed with a transgo plug. You can also block it with a 1/4" vb checkball I've heard.
You can also block the piston movement with two gen 1 sbc rocker nuts and one rod bolt nut. No joke they're the right height, but thats if you really want to rig it.

has taken 10 second passes in the 1/4 and a bunch of 1/8th mile runs. also lots and lots of abuse on the street. not harsh at all IMO.

Also, I thought you weren't supposed to raise line pressure AND add a shift kit, since the kit physically boosts pressure and the tuning does it through the computer. Everyone else on here has said that that's the perfect way to blow a transmission.
Lastly, how does the kit allow you to have different firmnesses of shifts at partial and WOT shifts?

Do you know with the transgo 1&2 kit (for the th400) they include two sets of valve body gaskets? Why? So you can take the vb plate off to make changes if needed.
Now why do they say install one to three washers? Why don't they just give you one big spacer? Well because you need to fine tune it to your personal taste, how you want it to feel when it shifts.
To change the washers you need to take the pan off and remove three bolts, not the most difficult thing to do.
I took my whole vb off and re-did a few things when I put my kit in. Just to get it to where it felt the way I wanted it to feel when it shifts.

Take my word on it, I drove mine to work daily communting 25mins between cities. You'll be asking yourself if you can put 4 or 5 washers in. It at the time was only a 13.0 car. It's not as bad as youre thinking. 3 is just nice, doesnt take any driveability away from the car.
You'll mostly feel it only at WOT, which is great. You wouldnt want to be flooring it in bad weater anyways, so it wont affect driveability.
Scotty you will be fine with 3 and it doesnt shift harsh at all when you do normal driving, now if your foot gets a bit heavy than you will really see the difference between one washer or 3.
But put in a billet super servo and drill the second feed as big as you can and one washer is going to feel very firm.
I've experimented with different things before, I blocked the movement of the second accumulator by using 3/8 nuts on the pin (much like the spacers in a B&M kit) and it was annoying as hell. It would chirp the tires at 5% throttle, and this was with a 553 servo and .110 second feed.
What the transgo washers do is limit the movement of the piston and tighten the spring.

I'm fairly educated about most areas of F-bodies, but when it comes to shift kits and trannies, I'm lost. I'm likely one of a few possible local guys install this kit. Each one of them has done it before, so I'm guessing they'd know.But I don't want it chirping into 2nd at 5% throttle like you said. That's simply ridiculous. I only want it chirping second when I get on it at maybe 60% throttle or more, something like that. So what would I tell the installer as far as how much to drill the holes and such?
Thanks guys.
2) look up my friend "Stu's WS6" - named travis and in the same area as you on this board. probably know him. he knows his autos and his ls1s. PM him or something.
again you are way over thinking this. hell if anything you are gonna be disapponted with teh shift firmness after building it up so much. my tranny (read my first reply) doesnt chirp anything. that is a line pressure issue.
