Corvette Servo: where to get?

[ntsqd]

Or p/n's would be handy.

& yes, I searched, and searched, and searched and what I found (going clear back to 2003) was lots of people saying they got one, but no part numbers listed.

try PATC aka 700 Raptor people. Google will lead the way. They sell parts individually.

I ran across a couple negative posts about Raptor. Didn't really read tham as I didn't think that was what I was looking for. W/o opening up an argument can you elaborate on them?

Part # 7-2P


I'd also recommend a .472 boost valve which they also sell.

Find a distributer here:

I like dealing with a local auto transmission parts supplier. Got everything I needed to rebuild and improve my 700 in one stop. Shift kit, boost valve, servo, firmer springs, upgraded sun shell and rebuild kit with a reman converter. Total cost was around $450-$500.

In this 700's case it got a std rebuild a couple years ago. 1-2 shift feels a bit lazy and my local auto trans ace suggested that I change to this servo. I was going to have him just deal with it, but he's been so busy lately that I'm going to have to do it myself if it's going to happen b4 the Vegas to Reno race.

What function does the "boost valve" have?

I bought mine at oregon performance transmission. They sell them on ebay or on their own webistie. The corvette servo should firm up the 1-2 shift and hold 2 gear stronger. Here are a bunch of pictures

a) i never had a problem with PATC

b) they sell parts new... a corvette servo from them would be just like a corvette servo from anywhere else. I dunno what their price is, but I have found that some of their individual components are very well priced. They had the absolute lowest price I've ever seen on short 32-spline th400 output shafts, for example.

I bought a 700r4 band drum from PATC. The part shipped fast and looked great. They also had the best price I could find.

Sounds like it could be be the 1% that any business always has then. Thanks!

Whats the exact application for the Corvette servo? (years?)

Everyone else is probably selling reboxed GM pieces, for more than GMPD would sell it to you for.

I hope someone comments on the boost valve, I know it's a typical upgrade. I *believe* it has something to do with upping the fluid pressure.

I did the exact same thing as you.Recent overhaul with a B&M shift kit.The shifts weren't firm enough especially under load driving on the sand.Put in the TCI servos and now it's solid shifting.

Appearently the boost valve is what it sounds like it would be. If I understood correctly it boosts line pressure during shifts. I was told that for my application what's stock is likely the best to use.
