Transmission Servos and Servo Covers



Billet Servo Covers
These CNC-machined billet aluminum plates cover the servo with style, and precision construction assures an excellent seal. Servo covers are available for the Powerglide and the Ford C6 - which employs permanent lip-type seals to conform to various transmission case bores. Powerglide units feature an anodized finish and ARP bolts.

SUPER SERVO CUTAWAY

Powerglide Super Servo
ATI’s new Super Servo (PATENT #8,250,967) gives the ability to increase the servo bore from the stock 2.750” bore to 3.250” on any OEM or aftermarket Powerglide case. This increases the servo pistons apply area nearly 30% from 5.93 square inches to 8.29 square inches. With this additional area you are now able to increase the band’s clamping force equal to what you would have running 300psi of line pressure, however you only need 215psi to do so! Take a look at these numbers:

5.93 x 288psi = 1186 lbs
5.93 x 300psi = 1779 lbs
8.29 x 215psi = 1782 lbs
