CR2 25300 EPC Solenoid Blocker for 2011-2019 Duramax with Allison Transmission

 

This will take place of your EPC Solenoid in the valve body, and it works as a fooler plug in the bore. The factory solenoid will snap back into the back of the plug and remain plugged into the factory wiring harness. The Factory LML/L5P Allison transmission runs at 80 PSI of line pressure. On shifts the solenoid will spike the line pressure to 230 PSI and then kick it back down to 80 PSI after the shift has been made. (not enough to hold any addition horsepower) The CR2 EPC blocker will make the transmission run at a static pressure of 230 PSI and will increase to 280 PSI off idle also eliminating pressure drop on shifts. This allows much more clamping force to the clutch packs in turn holding more horsepower and greatly improving shift quality and longevity of the transmission. The install is simple. It takes about one hour with no need to drop the valve body out of the transmission. Simply drain fluid, drop the pan remove the factory EPC Solenoid snap it into the back of the EPC Blocker and install the plug like you would the factory solenoid. Reinstall pan and fluid and you are done. Eliminates the need for line pressure increased transmission tuning.

Good quality
Color: Crisp White, Size: Medium
Fit is great, feels like a durable material. Generally a very nice shirt! Bought this for a 5’ 10” male who is 150lbs. Medium was just right, with a little bit of breathing room.

Good for an emergency only
Color: Crisp White, Size: X-Large
Shirts are good overall, but the material is too light ... if you are hairy or have dark skin, you need an undershirt; otherwise, it looks like the shirt is dirty.

Great shirt for Price
Color: White, Size: Large
Seem to fit true to size and long enough. I cannot stand dress shirts that are too short on the sides and become untucked. I am also getting these embroidered with a company logo to turn into work shirts. I like the oxford feel, buttons are tight fit, arm length is hair long for me (5'11") - but for the fit they fine. I purchased four of these, all were consistent with one another, no surprises.

Might buy a couple more.
Color: Demin Blue, Size: Large
In the process of losing weight and needed a nice looking shirt for work without spending a lot of money on something that will only fit for a few months. This did the trick! Fits well, looks nice, and at a great price.
