valve bodys are in AUTOMATICS! just to be clear. How your friend is tired of the clutch on a manual truck and he's adding a valve body is beyond me! Sounds like your friend is an idiot.
Valve bodys are the brains of an automatic transmission(old school.....new school it's all computer and brain). A manual valve body does not allow trans to shift on it's own....you must shift it yourself....thus making it basically a manual w/o a clutch w/o ability to put it Drive and let it shift itsself. They control traction and transoutput and shiftpoints(the drive does that by shifting) My Chevy is set up like that with it's 475hp 406sbc and TH400. manual valve body, a nice quarter stick shifter, sticky tires, and 500+hp on tap = neck snapping better than sex feeling.
you dont want it in a lifted truck. it's a 'gofast' item.
