About Us

From what began over 25 years ago, RPM Transmissions continues to be the leader in performance-based transmissions. Rodney Massengale, owner, started the business in a Chrysler town where he gained the reputation for building the strongest and baddest transmissions around. Initially dealing with frequent 200-4Rs found in Buick Grand Nationals, RPM Transmissions has evolved into becoming the experts in GM and Tremec drivelines like the 4l60e, 4l80e, T56, Powerglide, TH400, and more!

Today, RPM Transmissions continues to deliver services and products that continue prove themselves on street and track platforms. We strive to be the best in both, customer service and workmanship with every customer order. The process begins with our sales professionals and techs who are ready to provide you with the proper guidance for a successful build.
