This Allison Transmission EPC fooler takes the place of your current EPC solenoid. The factory transmission alternates pressures between 80psi while driving down the road, only when shifting will the transmission be around 230psi.

• This plug will allow the transmission to stay at 230psi at all times. This greatly helps with clamping power of the clutches in the transmission
• This plug is a great addition to anybody with a modified truck or tow rig
• EPC fooler will fit 2011-2019 LML/L5P Allison's

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!
