    Easy to install
  

*by R***9 on Reviewed in the United States on August 4, 2024*

Boosted pressure under towing. Easy to install could feel a better shift. Quick and not sluggish but not harsh.

    Great product
  

*by D***. on Reviewed in the United States on November 16, 2019*

This is a great product. I put it on my 2018 Ram 3500 6.4 Hemi. It has the 66RFE . With a little work it has lots of power. I will be Procharging it next. The Trans liked to lag between gears or not fully engage. Not sure which. Checked on line. I seen the RFE trans all have this problem, it seemed. After installing your product. It does not seem to lag much if at all. Its so easy to install. Will see in time if it throws a code. As for now it works great. Thanks

    Speeds up your shifting for sure.
  

*by Z***H on Reviewed in the United States on January 23, 2024*

A good cheap upgrade for your 45 or 545. It's been working great for a couple of thousand miles now. Doesn't firm your shift, just makes it faster. Which I love. Less annoying in between as it goes between gears.
