Got an inside on a new product from TCI that basically does exactly what we have been working on in the forum. The valvebody dumps pressure internally to make the glide drive like normal. If you have questions about it...I am sure that TCI would further comment on it here since they visit the site regularly.

Sounds interesting, but I think I'll stick with my Bushore-style hand valve on my glide...

I have a TCI glide we ran 2 years ago, it would act like it had a torque converter at idle and just off idle. We thought it was supposed to do that! Dose it mean I somehow got hold of a goof-up that worked out for the better? I went to a Bert because of trouble busting the cases on glides.

Brad's transmissions in Whitehouse,TX has been doing this for a long time. It is like driving your pick-up, no lurching and trying to stall at low rpm. It is the way to go in a glide.

The TCI Circlematic tranny works like a standard, it can be operated of a clutch pedal for take off, you engauge the clutch pedal just like a standard tranny, put tranny in low gear or reverse and release pedal to move, only time clutch pedal is needed is just for take off, this can also be achived with a shift lever also instead of a clutch pedal.

Yes sir, mod you are correct, but they have just developed a new valvebody that doesn't require the clutch, pedal or anything. Drive it like a regular tranny.

It is still in the R&D stages and hopefully be ready to sell January 2002. This valve body is not like others that do not use any external linkage. The others bleed pressure off in lo and hi gear. Ours will not operate like that. We have seperated Lo and Hi gear in the valvebody so there will be no pressure loss in hi gear.

Sounds like a good idea. I have thought about running a glide behind my mopar, but have heard horror stories about cases braking in the middle of a race. I also heard that there is a bracket of some kind that will help this. Anyone know about it?

The best way to runa a brace is to "cradle" the transmission. Bolt a piece of square tubing to the crossmember mount on the tailhousing and drill 2 holes (front to back) in it, then run steel rod or something similar from there up to your midplate and drill holes for it. Do this on both sides and thread the ends and use lock nuts on them. Wayne Brooks has run this setup with A TCI transmission for a few years and hasn't broken a case yet. Another thing to make sure on is that you have plenty of yoke movement. Especially if it is a 4-bar car.
Use a long chevy 700R-4 yoke.
Good Luck!!

Like TCI said, use a long slip yoke. Jeep Cherokee uses a Dana slip yoke that is just like the 85 dollar Coleman yoke, for 1/2 the money. I have had no problems in 3 years with them. They fit a Bert also..

TCI maybe on to something, but Brads in Whitehouse TX. has it figured out, this is the same unit he sells through Midwest and I think Smileys. I've used them for two seasons and the only real problems I have had are broke cases. Brads great about helping with problems over the phone and his prices are fair.

I myself cannot understand how people are having problems breaking cases on powerglides. I have run them since '94 ( with the TCI Ciclematic Valvebody )and the only case I have broken is when the rear u-joint let go this year!!
