Rules state OEM case. Put in a direct drive TCI clutchless valvebody to try and go faster. After two races, cracked the housing. Solid motor mounts and tranny mount. Is there a trick to stop cracking the cases. Any help appreciated. I know a three speed is an option, but alot invested in this powerglide setup. Thanks, Race Also, anyone running this new valvebody? 1st gear only workes when tranny is cold. Any ideas? Called TCI but no luck with help.

Ive heard said that if you are running solid motor mounts the tranny mounts should be stock and vica versa. Eddie

I run open wheel mods, we ran glides in my stock car and then in my mod. I ran it in my mod for 1/2 a year without a problem. Then it started breaking the case, not the bell housing the case right in the middle. We broke what seems like a 100 cases, then went to a 3 speed manual. Only thing I could figure because we tried every different mounting type imaginable, was the chassis was twisting. I bought a brand new car and picked up a tranny sponsor. But he wanted to use the glides. I stopped breaking cases but then I was stripping clutches and bands, even a TCI. After only making 2 or 3 laps each week before failure for 5 months, I dropped the sponsor and started running manual trannys. I will never touch a glide again. Thats just my experience with them, other people never have a problem. But the money I spent on all those glides, I could have bought a Bert.

I wanted to stick to my glide too because I had some cash in it, but I gave up and went to a 3 speed and all my troubles (trans related anyway) went away. Anyway...try a mid engine/trans mount set up. It puts a lot less stress on the trans case.

i had the same deal with the tci circlematic i burned it up twice in the first 7 or so races running it in low. killed my points this year i ended up 10th wich is okay but the tranny went the 2nd time on double feature night. i called and wrote to them and they offered no help other than telling me it was my fault, we put in a stock one that had been rebuilt in 88 raced in 89 and sitting in storage since, i changed the gasket and filter and it has been working great since.go fig wish i had known that before we spent $1100 on the tranny and coupler originaly and then another $600 to have it rebuilt the second time. now it sits in the shed outback waiting for me to pull it apart.

In the paper work for the TCI it used to tell you NOT to run it in first.
We have run glides in 800hp unlimited modifieds and never broke a case. We ran a motor plate and bolted a stock mount, the mount was bloted to a plate that had a stud out of each side. We used two swaged tubes with a rodend bearings on the stud, the tubes went up to a bracket on the back of the motor plate where two clevis mounts connected it to the block. This just held up the back of the trans so bouncing wouldn't bust the case. I still have a glide that has been run for 3 years with just a freshen every now and then.
