question about manual valve bodies - 05/11/10 10:05 PM

If a car has a strip B&M shifter in it (where you can only change the gears manually, meaning there is no "drive" gear where the transmission upshifts/downshifts automatically) could it still have the automatic valve body in it or will the shifter only work with a manual valve body? I bought a car from a guy and the car has this shifter in it (the shifter works) but I'm unsure whether or not he put in a manual valve body on the 727 or not. I've heard you can burn up a trans without the proper valve body installed.

Shifter makes no difference. It will have 3 forward positions along with PRN. It's the valve body that makes the trans have to be shifted manually. If you can shift it into third and that s the gear it takers off in then it's a full manual.If you can put it in third and it takes off in low then it's an auto or semi auto valvebody. look at the trans where the linkage hooks up and see if there is one lever or two. If there is only one and not stub sticking up where you could install another then that is a full manual valve body. If you have two levers then it can be auotmatic or semimanual. If it has two levers then you need to hook up throttle pressure(kickdown linkage)to it.The wromg valve body isn't what burns up the trans but not having throttle pressure linkage will if the valve body is made for it.

Wow thanks, thats exactly what I was looking for.

I went out and looked at the car today. It still has the kick down lever, it feels floppy and can be easilly rotated front or back. It looks like the previous owner hooked up some sort of strap to hold the kickdown lever in place (the strap is not attached to the lever anymore). Is it possible that this would remedy the situation or is the previous owner just an idiot?

some shift kits TF3 to make a manual VB would still have the TPV lever

and it would be tied back with the hillbilly strap

with it hooked to the TPV linkage the light throttle shifts would not be as harsh like a full manual with high line pressure

tieing it back will make it shift a little harder at light throttle

IIRC anyways

deff need to know what you got,your right,it will burn itself up in short order if it needs the TPV hooked up for auto/manual shifts

my CRT full manual VB has a nub and no linkage will fit on it

does it have any auto shift features when in drive?

If there is increasing spring resistance on the lever as you push it back, you definitely don't want it disconnected as it now is.
