Increase the durability, line pressure, and performance of the Allison transmission in your 2011-2019 GM 6.6L Duramax LML and L5P with the XDP EPC Solenoid Fooler Plug XD345. From the factory, the function of the EPC solenoid is to increase line pressure during shifts up to 230 PSI and once the shift is complete, drop the pressure back down to 80 PSI.

At 80 PSI your Allison can't hold the added stress of aftermarket upgrades or even towing a heavy load. The XD345 installs on the EPC Solenoid and installs back into the valve body allowing your transmission to effectively operate at 230 PSI all the time.

The line pressure increase helps to eliminate clutch slippage, poor shifting performance, and it extends transmission life. The EPC Fooler Plug is easy to install and does not require valve body or transmission removal. This product is an excellent modifications for any upgraded LML or L5P truck.
Features:

  • Easy Installation
  • Increased Line Pressure
  • Can Increase Transmission Longevity
  • Enhances Transmission Performance

Application Note:

  • The XD345 should not be used in conjunction with transmission tuning or other pressure adding modifications.

Warranty Info:
Products manufactured by XDP carry a 1-Year warranty against defects in materials and craftsmanship. The Warranty is Limited to one (1) year from the date of sale and limited solely to the parts contained within the product's kit.
