UnderDog Diesel EPC Solenoid Fooler Plug for 2011-2019 GM 6.6L Duramax

The stock EPC functions to modulate line pressure. During a shift, the transmission control module commands the EPC to vary mainline pressure. The pressure will rise from 80psi up to 230psi. After the shift, the pressure drops back down to 80psi. At 80psi the clutch packs don't hold the torque of the engine. Towing heavy loads or adding aftermarket upgrades adds even more stress on the clutch packs.

The EPC blocker kit quickly installs between the EPC solenoid and the valve body. There is no need to remove the valve body. Just drain the transmission fluid and remove the oil pan and install the EPC blocker.  Once installed, the EPC blocker will allow all the available mainline pressure, up to 230psi, to reach the apply pistons and clutch packs at all times.  

Warning: It is not recommended to run this plug in conjunction with other pressure modifying components I.E custom tuning. Please consult your tuner to make sure they gave no modified line pressure!
