Dec 07, 2009 Some like a manual valve body on the street, others say they are to harsh shifting for their taste andor want their automatic to work like an automatic not a clutchless 3 speed. So The choice is a matter of taste. Manual valve bodies replace the automatic transmission's valve bodies with a manually controlled one. It is similar to using an AutoStick or Tiptronic except that it does not automatically upshift or downshift if you forget.
How can the answer be improved? An automatic transmission valve body is a major component of a vehicle's automatic transmission system and directs pressurized transmission fluid to a network of valves that engage appropriate clutch packs for smooth gear shifting. These valves use pressure as hydraulic signals to determine which Manual Automatic Valve Body The Hughes manualautomatic valve body is designed for streetstrip operation.
It will let you shift manually or put the shifter into drive and the transmission remains full automatic. There are a lot of options in automatic transmission control. JEGS has a great selection of transbrakes for drag racing applications. Transbrakes allow a full throttle start off the line and full fluid lockup when you push the button to release the transbrake. Full manual valve bodies are used for How Automatic Transmissions Work.

Basic Function of Valve Body. All automatic transmission systems have a valve body which serves as its main control center. Basically, there are numerous passages and channels within the valve body which direct the flow of hydraulic fluid to different valves in order to activate the right clutch and shift the gear appropriately based on the driving situation.
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.
The competition valve body was designed for maximum performance and quick elapsed times in racing and offroad applications.
