How much difference in firmness is there between the VETTE SERVO and the BILLET SUPER SERVO?

I have both billets (intermediate for the 1-2 shift as well as 3-2/4-2 downshift and the overdrive for the 3-4 shift), the difference in holding capacity is around 40-50% over a stock servo and about 35% over a 'Vette servo. The OD billet holds around 50% better than OE.

Now, firmness is pretty stout with the billet intermediate one. BUT if you keep your 1-2 accumulator washer free (with a TransGo shift kit) and the 1-2 feed hole small you'll keep the shifts still authorative but not harsh.

I'm going back to tone down my 1-2 as I drilled my 1-2 hole to around .082" and I'm going to make it about a .063-.070" which will make the shift less stout but still have all the holding capacity. I'm also installing a hardened TransGo seperator plate along with pinless accumulators instead of my aluminum pinned ones.

Also, you'll want to upgrade to a piece from Sonnax called a Servo Release Check Valve (with either 'Vette or Billet), this prevents tieup on a 3-2/4-2 downshift...tie up could eqate to burned 3-4 clutches which is no bueno.



Make sense?

I think I am going to go with the vette servo....I want something that will throw me back in my seat when i punch it but not break my neck.

Where can i get that sonnax servo relase check valve? I need all the parts before the end on next week cause I'm going back to my parents house for a little while and he has the jack and tools I will need to install the parts.

You on AIM or yahoo?

Do you plan a TransGo setup also? If not, don't expect a whole lot from just that 'Vette servo. I'd pay no more than $10 for a 'Vette servo as at wholesale they are like $6-7. Also, may as well do the billet OD as you'll have it out anyway.

I'm going to make a list up later tonight if I have time or tomorrow with a bunch of lil parts for that setup.

I have all sorts of IM services but I'm at work currently...that's why I can't get that list together.

This is what I'm thinking for right now....money seems to get lost on its way to me.

Is that a good investment if I plan on getting a transgo later down the line?

Will those components give me noticeable firmness in my shifts, moreso than the tow/haul mode? Chirps?

Well the bigger TransGo kits have the .500" boost valve (PSK and HD2), I can get the HD2 for about $82. They are the same minus the video tape.

The HD2 kit, 'Vette servo, and billet OD would be a great setup. I'd add the few Sonnax bits I'm talking about to trick out the setup the best ya can with stock internals.

You should be able to bark the tires on a 1-2 upshift. 2-3 won't happen with a stock 3-4 pack due to the excessive clearance GM gives for a soft shift for Soccer Mom. lol

I'd get a big B&M SuperCooler also. Lower temps in there are a good thing. Hrm.. whatelse...

Oh, and a new filter w/ gasket. Make sure to get the old o-ring from the case also. :anitoof:

Awesome thx......I think for right now I will get that servo/valve kit from KDSperformance, and later get the HD2 kit.

Now is the Sonnax check release valve a different type of valve than the one that comes with that kit?

Yup, the Sonnax goes up into the case in the oriface for the supply to the servos. It's very trick. :D
