Chevy Silverado Transmission Servo

Here is the Corvette servo on the left as compared to the stock truck servo on the right. The Vette part has a smaller bore diameter, allowing for more surface on the apply area for fluid to push against, consequently giving the Vette part greater clamping for a firm, but not harsh, 1-2 shift. For truck owners, this is an economical, proven upgrade--just don't screw it up like I did.
