Trans mounts for DCT…Rogue fits nice!

[Nima Sab]

How did you use the transmission jack to support the transmission? I watched a video online on the rogue mounts (which i ordered) and was worried on putting the transmission on the plastic pan at the bottom of the trans because not wanting to take the risk of cracking the plastic pan along with internally damaging components. The video utilized a manual transmission was easily lowered on the trans jack, but with dct the fluid filled plastic pan is sitting at the bottom which i am afraid it is sitting on the jack with the trans pressure sitting on top of it will result in a bigger issue.

How did the dct users approach this tramission mount(s) upgrade? I know this is an old thread but any help would be appreciated!!!

Thanks everyone

Look how they supported the tranny @ 2:56

Block of wood across the pan, then a floor jack for a gentle lift. You only need a half inch to get the mounts swapped.

Thanks you all i appreciate the help. So just a block of wood and a gentle lift won’t crack or damage the pan? Just want to make sure before proceeding and damage anything!! Thanks!!!

Yep, you can find a metal spot to put the block on too. It’s just a slight lift.

Old thread but I feel like it's still relevant to post the experience for future readers (if someone finds this googling)

I just did mine yesterday on a DCT. One of the easiest transmission mounts I've done.

Buddy of mine had a motorcycle jack, so we used that. The "feet" of the jack lined up with the outside edges/bolts of the pan and spread out over the entire length. Jacked it up until it ever so slightly lifted the trans, you're putting just enough pressure to keep it from dropping but also taking pressure of the mounts.

The underbody cover obviously had to be removed but we didn't take anything else off (IE: Exhaust, heatshields etc.)
The top 2 nuts are a bit tricky to get to but absolutely doable with a 13mm wrench, if you have a thin enough ratcheting wrench, that might be even better. One side is easier than the other (if I remember correctly driver's side is easier)

For the other side, the heat shield does get in the way. I took the first two fasteners off and I basically bent the shield a bit out of the way, and I was able to put the wrench behind the shield and take the nut off that way. Just make sure to bend the heatshield back in it's "place" afterwards.

The torque specs on these is only 14-ish-ft/lbs which is a whole lot of nothing, totally doable by hand even with limited space for leverage.

When reinstalling the new ones, I loosely installed the bushings into the mount with the notches lined up, then leave the top nuts in place at the very top of the bolt, because the mounts essentially slide in so it'll be much easier to tighten once in place.

Reverse steps. Top nuts were done by hand set to gutentighten spec.
Bottom were torqued with an actual torque wrench.

So far so good, it definitely feels like it improved some of the clunkiness and what felt like slop with the stock. Stock were quite compressed when on the car and were quite "flimsy" when removed.

These helped reduce flex so much on my F80 MT6 that I had to try them in my F82 DCT. The fit is identical to in the stick shift, absolutely perfect! After a drive there's no added noise or vibration.

Hi sorry to revive this old thread but I think you may be in the position to help. I need my diff bushes and trans mounts on my F80 M3 replaced. I bought the 5 purple Powerflex bushings and their yellow 70A poly trans bushings. Will these be good replacements? Car is currently stage 2 but I may go flex fuel in the future. I have 295 semi slicks in the rear and dct. I wish I saw this review earlier because the RE mounts are cheaper and clearly hold up with a lot more power. Will the yellow PF trans mounts be similar enough that I don't have to return them due to NVH risk?

I'm also glad you mentioned you didn't go dual mount diff and it's fine on your power level, cost adds up quickly plus I'm hearing dual mount causes some NVH and diff whine which I may or may not like. For background I liked my 135i with solid diff mount/bushes and quaife lsd but I don't think it's comparable as the subframe bushings are so soft and I got no diff whine.

I’d do the Rogues and not risk the NVH that yellow poly may add. It’s a very easy job so you could try the yellow and change your mind later.

Not to be dumb, but what are the specific part numbers to the purple Powerflex and Rogue bushings being talked about here?
Thanks

Thanks. I noticed that the first link is for G80 cars though. I am an F80. I will explore the website though. Thanks

Sorry, here’s the F8X menu:

These Rogue mounts look very similar to my RevShift ones (80A). Probably are just about the same. Everything feels snappier/crispier. I can certainly here the clunking and clanking of the DCT when going from N to 1/D but I think that's more due to the RevShift 80A motor mounts I installed as well.

Could you please give me an idea of NVH on the 80A revshift? I'm about to get the 70A PF yellow trans installed tomorrow. Is it just noise changing from R - D, D - R? Mine does that already on the split, tarnished stock mounts.

Hard to say because I installed them at the same time as my engine mounts which I'm sure are the culprit for most of the NVH. I would say 80A on just the transmission shouldn't be too bad but 80A engine mounts produces very noticable NVH.

[xlcaliber]

Well, getting it installed atm along with PF purple bushes and yellow engine mount inserts, so I shall report back next week, I haven't been able to find any reviews on the PF trans mounts online.

[xlcaliber]

Ok, first drive back from the workshop with PF purple diff bushes, yellow trans mounts, and yellow engine mount inserts.

Only the slightest added vibration on idle, more gear noises though for sure and the shifts feel harder and more violent, potentially unsettling the car a bit more. One of my higher rpm shifts took me by surprise and unsettled my foot off the accelerator, leading to a bit of a kangaroo hopping sensation (it may have coincided with a bump in the road as well). Gear noises are clear in lower gears and R to D and vice versa. By that I mean thumping and what i assume to be engagement sound of the clutch unless it's grinding and my DCT is cooked. May try XHP tune to clean up shifts. Currently on GTS DCT coding.

Didn't hear any diff whine, there is still a clunk when coming to a stop although not as bad as when the rubber bushings were torn.

That sounds about right! I remember the first hard shift with the engine/transmission mounts and it felt violent.

From what I've heard the purple bushings introduce zero NVH so that sounds about right.

[xlcaliber]

It has settled down after a few runs, I'm happy to keep everything in. It feels like a street monster, a more visceral drive. I would like to add an XHP tune, if anyone has advice or settings to be used or how to dial it in etc.

[xlcaliber]

Installed XHP Stage 3 OTS no custom settings and it fixed everything. Smooth at slow speeds D1 and lighting fast, controlled shifts on S3 pulls. Sorry if this is getting too off topic, I can stop now.
