Let’s not forget one of the easiest, most inexpensive mods you can do to your 2011+ Allison. The CR2 is EPC fooler.

This will take place of your EPC Solenoid in the valve body, and it works as a fooler plug in the bore. The factory solenoid will snap back into the back of the plug and remain plugged into the factory wiring harness. The Factory LML/L5P Allison transmission runs at 80 PSI of line pressure. On shifts the solenoid will spike the line pressure to 230 PSI and then kick it back down to 80 PSI after the shift has been made. (not enough to hold any addition horsepower) The CR2 EPC blocker will make the transmission run at a static pressure of 230 PSI and will increase to 280 PSI off idle also eliminating pressure drop on shifts. This allows much more clamping force to the clutch packs in turn holding more horsepower and greatly improving shift quality and longevity of the transmission. The install is simple. It takes about one hour with no need to drop the valve body out of the transmission. Simply drain fluid, drop the pan remove the factory EPC Solenoid snap it into the back of the EPC Blocker and install the plug like you would the factory solenoid. Reinstall pan and fluid and you are done. Eliminates the need for line pressure increased transmission tuning.
