I'm getting my new clutch put in on Friday, and I was going to replace everything while I was in there. Energy Suspension boasts that their torque arm mount and tranny mount stiffen up your driveline like traction bars.... how mush truth is there to this? Is it worth buying these over the stock ones?

 

Check my sig. My car rides firmly but not harshly. I suggest you replace the mounts while it's convenient--with either rubber or poly (no doubt the rubber's crap by now).

 

I've installed the poly tranny mount after the rubber bit the dust. Wasn't a big difference but is worth installing just because of how long they will last compared to rubber, they also have a saftey feature built in so that in the event that the Polly rubber does seperate from the metal it will not allow the tranny to bang around freely there are metal tabs to keep it in place, Stock rubber does not have this.

 

the energy tranny mount wont break like a stock a rubber one. i have the t/a energy mount and the tranny mount no gripes here.

 

dont forget the secondary tranny mount bushings too. i just bough them. I really like the torque arm bushing and the tranny bushing really lasts.

 

Wait asec... secondary tranny mounts? That's what I ordered, but I thought that was the one in the middle! So... what did I order?

 

you ordered the 4 disk shaped bushings that support the mount that sits ontop of the crossmember but under the tranny mount. There is an additional plate lets say that the tranny bolts too this plate is supported by 4 bushings and bolts to the top of the transmission crossmember

 

Well, those probably needed replacing anyway.

The only main tranny mount I can find that's aftermarket says it requires shimming of the tranny and it's solid; so I must have solid other mounts.

Is there a direct bolt-in one?

 

call summit they have it in prothane and i'm sure in energy suspension.

 

secondary tranny mounts? ive never heard of that. i know when i did mine i had four bolts holding the cross member to the subframe rails and then two bolts holdin the top of the mount to the tranny and one stud with a nut holding the bottom of the mount to the cross member. i was told not to use the plate, i guess it causes a bad driveshaft angle.

 

I'm not sure what plate you are talking about, but I finally figured this all out:

Normally the transmission crossmember just bolts the the "frame" (unibody... you know what I mean )

The energy suspension secondary mounts go between the crossmember and the "frame".

As long as you get the energy suspension main tranny mount, which is a little higher to compensate for the secondary ones, I guess you are ok.

 

It was year-dependant; my '86 didn't have any secondary mount, but later models did.

For us that don't have it- know how the trans mount attaches to the crossmember by one single bolt in the middle? Well that area on some cars would crack, and the trans mount wouldn't be connected to the crossmember anymore.

So GM devised a little raised plate between the real crossmember and trans mount. This little plate bolted to the real x-member with two bolts, one on each side. Then the trans mount bolted to the little plate as normal.

I put the ES trans mount in back in 1996, after going thru two rubber trans mounts in two years. I haven't had to change it since. Yes, I used the preload plate... the instructions said so. And I've never noticed any extra vibrations from anything; if they're there, hell, I'm not in a luxury car, I could care less if there's extra vibrations.

As to the torque arm mount, YES it's worth it. I replaced mine when I swapped out my trans; seemed like a good time to do it since I had my trans out on the floor. It made my car feel more sturdy even when going straight! And it made turning a night & day difference. BUT- my old rubber torque arm bushing was worn out. If you've got a low mileage f-body and/or the rubber's in perfect condition, you might not notice an improvement. It was somewhat of a bitch to force the old bracket (like a hinged clamshell) over the new un-compressable poly bushings, but I managed with the help of a big pair of channel locks (tongue & groove pliers).

 

Yes my torque arm mount is nearly non-existent lol

So... I may not need the secondary x member mounts? I know my 84" had nothing of the sort.

Oh well, I pick the car up Friday! It's been 3 months since I had a car!!

 

is it possible that stick shift or v8 cars have the mounts because i have a factory 5 speed 84 z28 and i have them but i cant remember if my brothers 84 auto z has them

 

My 84 Z-28 was a standard, and it didn't have them... now that's weird!

 

well i found out last time my car was up on the lift i had secondary tranny bushings, never knew my car had them. does someone sell poly seconday trany mounts? becuz i only have 2 of the 4 little rubber disks and well i think i might want to replace them when i change my tranny mount.

 

energy suspension has them

 

lol thats what my post was about

 

both my '84 and '85 LG4/700R4 cars have the Secondary trans Mounts, maybe it was only cars made in CA that got them?

off the top of my head at almost 4 am it makes sense....


LOL

c-ya

zed

 

Well, my car doesn't need them... so I have no idea what they came on! I'll throw them in the classifieds.... thanks guys
