Product Description

Are you having transmission valve body issues? Well, you have come to the right place! RevMax is the industry leader in both high performance and rebuilt OEM replacement valve bodies. There are a lot of other competitors out there offering rebuild 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. After the valve body is assembled we test the solenoids independently to verify both hydraulic and electrical functionality equal that of a brand new solenoid. 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.

Unit does not include the Mechatronic / TCM module. If your TCM / Mechatronic unit has failed, you must purchase a complete NEW valve body from the dealer.
In order to verify that we have the model you require we will need the following information: Solenoid colors and number of solenoids and separator plate ID code (three digits starting with a letter)
This is a completely rebuilt valve body for the ZF 6HP series of transmissions. These units are notorious for several complaints, the most common being: 2-1 downshift bump , 4-5 shift flare harsh upshifts, harsh downshifts and TCC clutch failure and overheating.

This is what makes a RevMax ZF 6HP valve body superior to the rest:
