XDP EPC Solenoid Fooler Plug XD345 2011-2019 GM 6.6L Duramax
This product cannot be shipped to these states/provinces: CA
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.

I'm totally pleased with my purchase and all the up grades that I've done to accommodate the FSD Heat Exchanger. Everything is working good and if i could i would add another one and also add a coolant bypass.
