Description
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.

Great Investment

Ordered this along with the PPE deep trans pan, well worth the price. Shifts smoother, especially when towing heavy. XDP came through like always. Order 2137824

Trans Saver!!
Austin (Illinois) | January 22nd, 2023
Have a 15 LML with basic bolt ons. Trans was slipping quite a bit and one day locked itself in 4th. Before doing a built trans, I wanted to see if this solenoid would work. To my surprise the trans seems to be holding up great. Did 5 launches back to back (Not the brightest idea), and the trans was solid. Will be getting a built trans in future, but this solenoid did the trick for me. Well worth the money!
