Anyone Install Their Own Tranny Mounts - BMW Forum

Autotechnica · 09-22-2004, 05:57 PM

I just got my UUC tranny mounts and enforcers. I want to do this myself, is it difficult?

I assume you just jack the car up and hoist up the tranny.

Any help would be apprecaited.

Thanks,

Bry

It should be very easy. From under the car they are easily accessible. Though you my have to drop the tranny crossmember. But if you are mech. inclined in any way it should be easy for you.

Thanks, doesn't sound too hard then.

I can do stuff like dampers, springs, sway bars, exhaust, oil changes, etc.

basically I just hold the tranny up with a jack and then remove the crossmember? Then just lower the tranny?

Jack the tranny up with a floor jack. Take off the nut on top of the tranny mounts. Remove 4 bolts on the crossmember. Take off crossmember. Instal new mounts. Put it back on. Lower jack. Zoom zoom, 'these new mounts is kewl ma!'

UUC Reds?

Got the UUC reds, I can't wait to install them. If I have any complaints about my car, it's the sloppy shifter and all the play in the tranny.

I will be putting UUC reds in my car sometime in the middle of next week, as well as a UUC short throw and DSSR. :-)

Good luck with your install!!!

I have UUC red tranny mounts with cups. It will transfer alot of vibration through the chassis to the passenger compartment. It was more pronounced when the A/C kicks in. The cure was not to use the cups , it's still stiff as hell and if you compare the hight between the two with the cups off they are the same.
I also have the delrin carrier bushings and an Evo3 short shifter.

No worries, I don't even have A/C

How bad are the vibrations? I still want to use the enforcers. Does it make the interior panels rattle?

Did you install them yourself? Anything else I need to know before I begin?

Thanks,

Bry

Bah, rattle shmattle. The only time it rattles is for the first 300 miles and then it will go away. Just make sure you properly torque them down.

My panels don't rattle at all, and I've pulled most of the insulation I can find.

Hey Kev,

You have them installed on your car? What are the torque specs? I have also removed all foam insulations and sound deadening. Just wait till the winter, everything will start rattling. I hate winter

Thanks,

Bry

Lurking deep in the recesses of my mind is something in a multi part article from European car about there being vibration if you over torque the tranny mounts. Apparently it is a relatively low figure. You may want to check out the recommneded torque figures from perhaps UUC.

Hope my lousy recollection was in some way helpful

Helpful, thanks

Time to go out and buy a good torque wrench. I have a crappy toque wrench which just has a needle with a scale on it. Problem is I can't read the scale if I have to get under the car to install it.

Kevin325i · 09-24-2004, 04:03 PM

Get one of the click type ones. I absolutely love the ones we've got. One is a big one in ft lbs, and the other is a small in lbs one. It's like 16 ft lbs or something. They send you instructions with the mounts.

Yes they're on my car. I also experience the rattles of winter. I wake up and it's like 60 degrees hop in the car and the doors rattle it so annoying, but then 3 hours later when it gets warmer it all goes away.

I've installed the reds with the cups, no real noise increase. Although I did follow the proper torque numbers. The only increase in noise is that I can hear the synchros in the tranny (slightly) if I don't rev match when downshifting. Basically if I didn't tell you I had them you wouldn't know by the sound.
