HP Autosport || Rogue Engineering Upgraded Transmission Mounts

HP Autosport · 02-28-2013, 05:51 PM

What is a transmission mount?

The transmission mounts in a BMW are a common part that is frequently overlooked. They are required to do many things in the vehicle, yet are not quite suitable for those who actually drive their BMWs.

The transmission mount is designed to do the following:

Help stabilize the transmission under vehicle load allowing the shifter to engage into gear properly
Isolate vibration from the drivetrain to the chassis
Under engine load, the transmission can wiggle left and right slightly. This wiggle gets worse when the car is being driven in turns. This unwanted movement may potentially causing the driver to miss shift, a costly error which will always be considered driver error.

Solutions to a Potential Problem

With this unwanted movement, what are your choices as a consumer? There are some BMW factory mounts that can improve this situation. However, they don't fit all cars and only offer minimal benefits. There are race-type mounts which can stabilize the transmission so much, you can feel every last vibration. There are even other aftermarket mounts designed with reinforcements to make mounts even more stiff. You could probably even find someplace that offers solid aluminum mounts, for the diehards.

When we sought to have our own transmission mounts produced, we wanted them to be compliant for street use. We wanted to ensure that there were no compromises in performance, no extras to buy, just a mount engineered to do what we want without needless add-ons.

What we have is a transmission mount made from Neoprene rubber, with a completely different shape than the factory mount. The hourglass shape of the factory mount is not the best for stabilizing the transmission. By changing the shape to the cylindrical shape of the Rogue Engineering mount, it reduces deflection significantly.

We have designed this mounts to minimize unwanted transmission movement while maintaining vibration dampening characteristics. No additional adapters, mounts, cups, or braces are required for our mounts. To eliminate even MORE movement from the transmission, you must go to the root of the issue, the factory motor mounts. Unfortunately, BMW Motorsport motor mounts (if available), can cost over $500 or more.

Common Myths

There are companies out there pushing their solutions to unwanted transmission movement which are no suitable to street driven cars. Sure, solid aluminum or Delrin mounts product a nice, solid feel, but at the expense of tremendous NVH. In a racecar, this kind of noise and vibration is commonplace. However, in a street car, this is not acceptable.

Using external "cups" or bushings with "bolt-through" designs are excuses for poor design, over zealous claims, or just a way of promoting a gimmick. Being realistic about the amount of play at the transmission that can be minimized is important. Thinking these small bushings can eliminate it all together is unrealistic.
A Simple, Affordable, Complete Package

The Rogue Engineering Transmission Mounts are sold as a pair, and come with Grade 8 Zinc plated hardware. Unlike other aftermarket mounts, the mounting plate and studs of our mounts have been Cadmium plated to prevent corrosion.

Currently, the transmission mounts fit the following vehicles:

All E34
All E36 including M3
All E46 including E46 M3
All Z3s include M Roadster/M Coupe
All Z8s
All E39 including M5s
All Z4s
All E8x including 1M
All E9X

Application Note: Transmission mounts are NOT required or necessary for vehicles equipped with automatic or SMG transmissions.

What sort of warranty comes with these mounts? I've heard that they break.

One year against defects and workmanship.

We have never seen on break unless it was improperly installed or abused, and we have been installing these for years from E36/46 street and race cars to late model 400+ whp 135i and 335i's.

Guys, look at the difference!! I can flex the oem with one hand...what do you think 500+ lbs of torque is going to do? Yes I got these from Harold amomg MANY other things LOL!!

robc1976 · 02-28-2013, 10:24 PM

I need to do a review on these, car seems to shift much smoother and harder!

cleex024 · 03-01-2013, 12:07 AM

I had my exhaust off already, but you may be able to do it without dropping the exhaust....but dropping the exhaust is maybe 15 mins?

tht ones NOT need to be removed, I posted in comments this did not need to be taken down...I was doing a Wavetrac, subframe bushing, lockdown differential install at the same time lol!

robc1976 · 03-01-2013, 12:53 AM

Guess I didn't added it....will add that now!

A noticeable one, exsoeacially at my power levels...this also adds safety since the tranny does not move and put unwanted stress on drivetrain. It shifts a lot better and seems to even shifting from say 3rd to 4th it has ess delay.

No e60 support? Why?

turb0mik3 · 03-01-2013, 12:49 PM

Harold, count me in on a set once I get my car back. Still need to do this and subframes, haha.

Mike,

I'll set aside one pair for you. Give us a heads up on when you would like to do the subframe bushings.

Harold

So..... none of what you're experiencing is also due to the quaife, diff lockdown, etc that you were doing at the same time??
