so....now im trying to decide on wether or not to get a manual valve body or keep it automatic.......

I've got a friend with a manual valve body in his car and he loves it. Doesn't seem to be too much of a hassle for him, and it'd be nice to be able to hold the car in a particular gear.

That said, cost not being an issue, I'd still go with a T56.

I rode in a monte carlo two nights ago that had a manual valve body and I didn't like it at all! In every gear he would le toff the throttle and the rpm's would go to like 600-800...then he would hit the gas again and the car would "catch" at the appropriate rpm...so the car would get power to the wheels at weird times. All I was picturing was me doing that in a corner and totaly losing traction.

I still plan on the T56...just doing this automatic so I can get back on the track asap!!

That's bizarre. I've cruised around in my friend's Roadrunner with a manual valve body and it behaves nothing like that.

Hate to ask, but is your friend sure that he doesn't have other transmission issues?

i dunno....but it's possible i guess. Im just gonna keep it regular for now...and save up for some other goodies...

I think it has something to do with the gear engagement being somewhat "passive" via a sprag (aka overrunning clutch) vs by active mechanical means such as clutches/bands. Link.

Doug's experience would have been with the overrunning clutch allowing the engine rpm to drop below what the D/S rpms would require (everything aft of the overrunning clutch is allowed to "freewheel" or overspeed what the engine rpm input and the nominal tranny ratios would otherwise dictate). When the engine rpms come up to match whatever the road speed and tranny gear engaged require, only then is torque from the engine applied.

You wouldn't have any engine compression braking to speak of.


As I recall, the Torqueflites worked a little differently than the GM Turbohydros. I think there was an overrunning clutch for low (1st) that could act to give you 1st in the event of low-reverse band breakage, but I think that most shifts were accomplished by band and clutch activation/deactivation. Weren't the TF manual valve bodies all reverse-pattern?

Side pic of the new trans...Billet Servo...Billet Front Drum...Billet Input Shaft...Hardened Everything else...this one shouldnt break!!!



Old unused GN converter that I was planning onusing while I waited on the PTC unit...



New Pro Torque Converter!!



Me making the new trans cooler lines..

[SicMonte]

New Flexplate, PT Converter, Trans and new trans pan all installed!!



Car as it stands tonight. Still need to wire up and plumb the trans cooler and re-install the radiator.
