Transmission Mounts: Rogue Eng. vs E46 M3 and others

[skyscraper_g80]

I have the E46 M3 transmission mounts. No noticeable increase in NVH and shifts felt cleaner and more positive. Recommended, although I've heard good things about the Rogue mounts too

Here is the 335is trans mount - http://www.realoem.com/bmw/enUS/part...&q=22316799331
It appears to be simply a Super-seeding part for all e8x e9x from 2011 onwards.

Interesting - is it incorrect to assume that the 2011+ E82s then have this mount? Or is it just a supersede if the part requires replacement?

Cant say, assume the vehicle has the default part on realoem as per year/month of mfg. Probably is the previous PN version

This part number extends across all e46 non M and also more interestingly the Z4 M coupe. I don't know how recent it is or any reviews of it.

Ok guys, I did the 335is engine mount(s), RE transmission mounts, CDV delete and replaced my guibo, and had my clutch line flushed.

Impressions?

The engine also had headers installed at the same time, so there a bit more "noise" now, though the car sounds and behaves like stock when idling. The shifter does still seem to "vibrate" in my hand and I can't recall if it's more or less than before..I haven't really gotten to drive it calmly....

Because I've been going full bore WOT doing crazy upshifts at 7000rpm and it's perfect. The shift action is light and direct, it's like a bolt action for a gun. There is no feeling of the shifter being "caught" in between the gates, or feeling of the transmission "moving" during your aggressive driving, and gone is the "spring" feeling in the driveline - it's a very direct connection. I LOVE it.

I can tell you the torque loading on the engine when you shift, or let the engine brake is gone and if feels like one solid piece of the car, the shifts/RPM seem to drop quicker...which is odd (in a positive way) but it's awesome. I can't help but wonder WHY the car wasn't like this before -even something so small like the Transmission mounts - WHY the stock soft crap BMW?

Interesting you note this.

Whats the procedure for the engine mount swap? How is the engine supported?

I believe the engine needs to be lifted and supported to do the swap, and I replaced both.

Axiom - thanks for the feedback on this. I'm now also considering the 335is mount while doing the other driveline changes. You got this done at a shop? Any idea on labour on the engine mount swap? The trans mounts are pretty simple I understand, just trying to guage what the engine mount comes out to.

A local mechanic, and I can ask for you.

Well, I got off the damn fence and just ordered the Rogue mounts, along with a BMS clutch stop. Will report back once they are installed....going to do a CDV delete at the same time. Looking forward to falling down the slippery mod slope...lol

Please do because im thinking of swapping mine as well, so labor hours would be awesome to know ahead of time...

Thanks,on a side note I received my RE Tranny mounts. probably install either this weekend or next.

[Solo_M_Tech]

I had the UUC mounts and they are GARBAGE! anywho, I replaced them with the E46 M3 mounts and couldn't be happier. No change in NVH and less transmission movement. All around win!

[hyphy1]

where is everyone picking them up? realoem.com? turnerM?

[Taskmaster]

Ecs for the IS mounts, and the RE mount are from a vendor on here.

Well, so I went with the Rogue mounts, finally got them installed a few days ago. Went for a long drive and have acclimatized to the changes, and overall this is a nice upgrade. Note that I had the CDV taken care of as well as a BMS clutch stop installed (took 2 spacers out leaving a single spacer and the stop itself, that feels the most comfy for me), so the changes are not just the mount but I've tried to focus on my impressions around shifter feel and solidity:

- Definitely an upgrade over stock, the stock mounts as everyone has mentioned are quite soft and you can twist and compress them by hand fairly easily. Rogue mounts are beefier, stronger rubber - but they do have some give

- I was quite concerned with adding unwanted NVH into the car, it's a daily driver and I've had a car with Poly engine mounts before which over time drove me crazy. After debating between E46 M3 mounts and Rogue, decided to go with Rogue.

- I'm happy to report there was almost ZERO discernible change in NVH! Some people have mentioned there is a bit more clutch chatter, I haven't experienced any change (there was a tiny bit of chatter in my car stock anyway, if anything it's better now since I got rid of the CDV and I can modulate the clutch better). After driving a few days and paying extremely close attention, I can say maybe there is a 5% increase in drivetrain vibration which I can feel through the pedals. But it's not the bad kind, it's just the perfect amount to make you feel a bit more connected to the car - it reminds me a lot of my old E36 M3. Again, this is a DD for me, I am very sensitive to unpleasant NVH and this does not qualify as that in any way. I have not felt any increase in noise/sound, some had reported a slight increase in transmission whine but it sounds the same to me

- Shifting impressions are positive. I don't have a short shifter, just stock which I like just fine. My main issue prior was that occasionally I'd get rejected trying to get into a gear when shifting quickly. I'm happy to say that issue is now GONE! Drove quite a bit and ran up and down through the gears mixing in heel/toe downshifts aggressively, no problems whatsoever. So IMO this is the perfect "OEM+" type mod where one wonders why the hell it didn't come from the factory like this!

- Last but not least, I did experience one issue after install. When taking the car out for a drive post install, I noticed a knocking sound that I could feel in the floorboards when going over bumps and/or starting from a stop. Took it back into the shop and my mechanic noticed that the mounts are a *tiny* bit longer than stock, and he said this pushed the transmission up a bit and it was lightly tapping the firewall in certain conditions. So the fix was simple, he put in a 1mm washer between the brace and the body to compensate, and now all is well. He said the mounts might settle/compress and has marked it up so that at the next oil change he might just take out the washers. This was a bit strange since nobody else had the issue, may be a quirk just with my car and its particular drivetrain alignment.

Otherwise, I highly recommend this mod. I think this or the E46 M3 mounts are an easy and cheap way to "OEM+" the shifter accuracy and feel. It should've just come this way from the factory!

Looking to do similar on my car now, having grinding getting into 2nd so likely the synchro ring in the trans is shot but want to try replacing the engine and trans mounts first as a cheaper possible solution.

looking at:

335is Engine mount (passenger or "Right". pt number: 22116793240

135i Engine mount (driver side or "Left") pt number: 22116760330

Rogue engineering Trans mounts


For the engine mount repair - Realoem has what you need for the left/driver side, but doesnt show what I need for the passenger/335is mount:

Hex bolt with washer M8X45-10.9-ZNS3 x2 22116850329
Flange nut M10-10-ZNS3 x1 07119904670

I assume its the same bolts/washer/nut on the passenger side for the 335is mount. Looking at ECS tuning the part is listed as 'not fitting' on my car so I want to make sure I've got the right part numbers.

Thanks!

I don't have a direct answer for your question on the mounts/hardware, thought I would add the below in case you haven't seen these:

https://www.ecstuning.com/b-034motor.../034-509-005x/

I'm considering doing them as they are OEM shell with a solid rubber internal. Higher durometer than OEM but not stiff to the point you'd have issues with NVH. Something to consider.....

This is a great find, and would pair well with the Rogue Engineering trans mounts, which I prefer on the 6MT to the E46M mounts. So thanks!

Word of caution though, is that we have no demonstration of bushing deflection in these ECS products vs the OE BMW engine mounts. I'd imagine it's less, but HOW MUCH less? One obvious benefit is lack of fluid within the bushing. Spotted some fluid residue around my own R engine mount recently, so eliminating that potential issue would be a plus on its own for me.

But, vendors frequently advertise, Stiffer is Better! but with no documentation of the difference between their product and stock. A few supposedly "upgraded" products have been independently tested by forum members on the benchtop, unfortunately finding negligible differences.

I believe that's right. The Driver side is the same on all models, the pass side is unique.

Thanks. Can anyone please confirm this part (335is engine mount) fits on n55 (2012 -135i, build date 2/12).

pt number: 22116793240

According to this website: "OE engine mount found on 35is models, can also be used on other N54 vehicles as an upgrade"
