Product Description

48RE Towing Valve Body 2003-2007

Are you having transmission valve body issues or just looking to upgrade your valve body? Well, you have come to the right place! RevMax is the industry leader in high performance diesel transmission valve bodies. There are a lot of other competitors out there offering valve bodies and sometimes it may seem hard to differentiate what’s what and why ours may be a little bit more expensive than some, but there are a lot of reasons.

RevMax has been offering high quality computer dyno tested valve bodies for almost a decade. All of our technicians have undergone extensive training and are the best in the industry. Unlike our competitors, we do not do any reaming or valve oversizing by hand. Each and every valve body we rebuild is machined on our state of the art Haas CNC milling machines, just like the factory did when they made the valve body originally. These CNC machines cost over $100k each! By the use of these machines, we eliminate human error that is very common when valve bodies are machined by hand. The precise alignment of the reamer to the bore is nearly impossible to get perfect by hand and this is where our CNC machines thrive. We use a Rennishaw probe to dial in each valve body to the reamer prior to the valve being cut. This allows us to be within .0005” within the original centerline of the bore. Hand reaming is lucky to keep .002” tolerances. Being off by just .001” can cause valves to stick and side load and ultimately lead to complete transmission failure.

Each RevMax valve body has a predetermined protocol that is followed for each valve body type. This protocol insures that the customer gets the highest quality product each and every time. We do not just go thru and replace what is bad on each specific valve body, instead, a standard protocol is followed that replaces all known failure prone parts, even if they are still in good working order. In addition, we then check over the entire valve body to make sure that non problematic areas are in good working order and if not, we repair these areas as well.

RevMax has proprietary technology and workflow processes that make our product superior to the competition. We also have the industries best testing equipment. To start, we vacuum leak test each and every valve body after cleaning. Finally each valve body is dyno tested on one of our fully computerized valve body dyno machines. The results are compared against a brand new valve body and the data is then stored and available to be viewed by the customer if requested.

Our 47RH, 47RE, 48RE diesel performance valve bodies feature the following

  • Full line pressure in all forward gears. Unlike our competition that only gets full line pressure in overdrive or lockup, our valve bodies have maximum line pressure in all gears.

    I never knew about body would make such a difference. My 06 Cummins had a trans rebuild heavy duty Billet opponents low Stall high torque converter and had a shift kit put in. Since I started hauling more I did a lot of research on which valve body would be the best heard a lot of good things on revmax how to install I can’t believe how much more power it puts for the ground. I turned my tuner down now and I hooked up my 10000 lb skid steer it’s unreal how much of a difference and how much more power is put to the ground. Shift points are better and can actually feel when the pressure builds and tired getting put to the tires. Transmission rims cooler eliminated dead spot in 2nd gear. And still experiencing all the other things that has done better than I stock one my hats off to revmax amazing recommend them to anybody it’s worth the money 100 and 10%

    I never knew a valve body would make such a difference in my ’06 Cummins . Had a trans rebuild heavy duty Billet components lost all high torque converter and had a shift kit put in. Since I started hauling more I did a lot of research on which valve body would be the best, heard a lot of good things on revmax & was very impressed on how they explain the process of making their valve bodies. I have an edge tuner Banks intake with the Boost tube and intake manifold turbo back exhaust BD exhaust header. After installing this valve body, I can’t believe how much more power got put to the ground. Shift points are better, can actually feel pressure of the transmission building as it pulls harder and harder through the gear. The transmission runs cooler but dead spots are eliminated especially second gear, the shifting is perfect no more slamming into gear and still experiencing other things that are making the truck run better. Probably one of the best purchases I’ve made. My truck has over 350,000 miles on it and had the tranny rebuilt at 283,000 miles and just recently had this valve body installed. I pull a 10,000 lb skid steer quite often, now after the new install every time I go to take off from a stop light I still say to myself wow. Highly recommend revmax and their first class quality. I’m a lifetime customer after this experience.

    Simply the best. I had a local transmission shop in Phoenix Arizona build me a heavy duty towing transmission. It never worked properly. I suspected the valve body from the start. I bought the revmax valve body and it installed and it fixed my problems. Look no further, Period. The only transmission I will put in my truck will be from Revmax, learn from me please. These guys are the best.
