    Rated 5 out of 5 by from pressure booster for 68 RFE So far it is great. Added with a performance valve body and new shift solenoids. Hope to get 150K more miles from the Trans. Cummins will last 300K hopefully....

    Rated 5 out of 5 by from Proper shifting I bought this line pressure booster kit for 09 ram 1500 with the 5.7 hemi and 5 speed trans. I always hated the huge pause between shifts but didn’t want to spend $600 on a tuner. After researching this product in the forums for over a year, I pulled the trigger and I am very pleased with it. I am only using the connector as my trans wasn’t coming out just for the spring install. I followed the directions and have over 2k miles on it now. It doesn’t make the shift firm, not like a th350 or c6 with a shift kit. It does greatly reduce the big hiccup between shifts though. My truck now shifts like I would have liked it to from the factory.
