The automatic transmission valve body controls the shifting of the transmission. A manual valve body gives the driver full control over when the transmission changes gears. When you install a high performance transmission valve body assembly you also gain quicker, firmer shifts for improved performance and reduced wear. We offer valve bodies built by JW Performance Transmissions. These include forward and reverse manual valve body assemblies.

Automatic Transmission Adjustment, Tips and FAQ
A) An automatic transmission manual valve body is a modified or aftermarket valve body which puts full control of when the transmission shifts in the drivers control. Automatic transmissions normally shift, automatically, based on line pressures, vehicle speed, vehicle load and other factors which the driver has no control over. A manual valve body eliminates the automatic shifting function and puts control of gear changes in the drivers hands.
A forward or reverse manual valve body can be used in a street vehicle for quick tire chirping shifts, full control over when the shifts take place and to make driving your high performance street car even more enjoyable. Manual valve bodies are used in most every type of competition activity involving an automatic transmission, to provide the driver with the additional vehicle control offered by having the gear changes occur on command. Faster, firmer shifts for improved performance are also another benefit.
