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.

Looks as good as the genuine one.
This looks like a quality product, great for the price. It looked identical to the genuine Honda part but was $20 cheaper than the Honda one.

Highly Recommended – Saved Big and Easy Install at 83 Years Old!
Size: CF10134&CA11476
I’ve been taking my cars to my favorite garage for over 25 years, so I trust them completely. When they quoted me $150 just to install and purchase the cabin and engine air filters on my 2016 Honda Accord, I decided to try doing it myself. I bought this Cabin & Engine Air Filter set (fits Honda Accord 2.4L 2013-2017 and Acura TLX) for only about $27 delivered. What a difference in price! Installation was surprisingly straightforward. Everything fit perfectly with no issues. The only extra step was doing a simple factory reset on the control panel, which was very easy and took just a couple of minutes. At 83 years old, I’m proud to say I handled the whole job myself in my driveway. The filters seem high quality, especially with the activated carbon cabin filter. My car runs cleaner now and the air inside smells fresher. Excellent value and perfect fit. If you’re even a little handy, don’t pay the high dealer/garage prices — get this kit and do it yourself. Highly recommended! Would buy again without hesitation.
