You will need the two O-rings also. A red one for the Housing, and a Blue one for the servo cover.

When I did mine, I also installed:

8639164 Pressure regulator spring
8634940 TV Boost valve.

Under light throttle, it kinda lugs in third, but with moderate and heavy accell, it feels good.

i remember reading a post a few months ago with like 6 part #s for the vette servo.. anyone have that link???

 

6 part numbers? I think they were refering to the servo, housing, and one of each o-ring (4 parts total) I don't know where six came from.

Here is the link to the servo install. Sorry no PNs for the o-rings. Servo Install
