Abstract
Aspects of the present disclosure include methods of modifying a transmission valve body to increase a line pressure response in certain hydraulic shift control system configurations. In one example, a Daimler Chrysler 46RE or 47RE transmission valve body may be modified to have a higher and more rapid line pressure increase when the transmission is in fourth gear and when the torque converter clutch (TCC) is engaged. Aspects of the present disclosure also include methods of modifying a transmission valve body to allow TCC engagement in any gear. Aspects of the present disclosure also include replacement valve bodies, as well as kits for modifying a 46RE or 47RE valve body to perform like a 48RE valve body.
