Ok you Stock Car guys, I have a general information question. For those of you running a powerglide, or I guess any automatic.

If you run solid motor mounts, and solid rear motor mounts also. Do you run any mount on the tranny?

Nope, hang it on the rear motor mounts, and let the rest float.

I am not driving a prostock, but it would seem like you would x the frame and make a rear transmission mount off that, but I am just a 4 cylinder stock driver.Istock probably a lot more experience than me, by the way nice ride

No trans mount, just use longer block pins to support and align everything.

Im with the rest of them. On my dads IMCA Stock Car it has motor mounts on the back of the block and the tranny just floats with no mounts.

I don't use a tranny mount.

I use long dowell pins and rear engine mounts.

No problems in my first year with this setup.

We run a mount on the tail of the tranny. Probably don't need it but it just gives it a little more support.

Shawn,
We run 2 braces from the 2 upper bellhousing bolts down to where the rear tranny mount would go.Basiclly it's a support for the rear of the tranny.Been running that since '96 and no broken cases.Another guy up here bolts it to the block and that's it.

Racin5 is correct. You should always use a hanger as described by racin5 if you have rear engine mounts. Go to www.burtbrownracingtrans.com and look at the transmission brace that he sells. Once he says it was OK to copy it.

The brace is the best thing to do for a 'glide. The stock cases are weak and will break over time if tweaked too much.

I run urethane motor mounts and tranny mount. The tranny mount is tightened just close to touching but not quite. Just enough to let it float without binding everything up. I had a midplate for a while but broke 2 tail shafts (I bought a Deadenbear case 2 years ago). Went back to the urethane trans mount semi loose and it's been good for a season and a half.

If you run a glide, make sure to get a new driveshaft or a long yoke. A stock metric driveshaft is about 1" too short.

Thanks for all the replies guys!!

I ran the Bushore glide in my hobby car with solid motor mounts and just the rear tail mount on the tranny (not solid). On my Stock Car its just the two sets of solid motor mounts, frnt and rear. No Tranny mount.

It just gives me that false sense of security with it floating there.

Thanks again!

After years of recomending no rear tranny mount I have kinda changed my mind and the reason is if you run on a really rough track with tons of bite (lets say you go run the track in the next town) and you have a driveline problem the tranny can come flying right out of the car. Never seen it until a couple seasons ago when our track went rough and really good bite. Use a urethane mount and it should not move the tranny at all when tightening or stress it at all. You can run without a rear mount, tons of guys do it but just for safety I would use one.
