A little-known fact about factory LML/L5P Allison Transmissions is that they run at 80 PSI of line pressure. When it gets ready to shift, it spikes up to 230 PSI and then shoots back down to 80 PSI after the shift is done. This jumping in pressure of spiking and crashing puts stress on your transmission while giving you zero extra horsepower. CR2 Performance & Fabrication has the solution with its EPC Solenoid blocker. How it works is it replaces your EPC Solenoid in the valve body and works as a fooler plug in the bore which, in effect, makes your transmission run at a static pressure of 230 PSI and increases to 280 PSI off idle. Eliminating the pressure spikes and crashes, giving you much more clamping force to the clutch packs; improving horsepower, shifting quality, and longevity of your whole transmission.

Installation is simple and takes about an hour. Drain the fluid, drop the pan, remove the factory EPC Solenoid and snap it to the back of the EPC Blocker, re-install the plug like you would a factory solenoid, put the pan and fluid back and you are done!

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.

Purchased several shirts, all were great quality. You never know what you’ll get when you purchase sight unseen, these are worth it. Great value, style, and comfort. Color is exactly what you see online. True to size.
