Transmission Mount Bushing Insert Kit

[lllnavarrolll]

Hello does anyone have any experience with

Powerflex Transmission Mount Bushing Inserts? If so what color did you go with Yellow or Black?​

 

[SX 10TUS]

Yellow

Haven't noticed any increase in NVH

Gear shift feels smoother, engine rocks less

Mine is a V6 manual, 90% road use

Did you install them yourself? I took a peek back there and it looks like the rear trunk box has to come out for one to get to the rear transmission bracket?

Front bracket looked even more difficult since the bolts look like they interefere with other sub components?

No, had them done at the same time as my 3rd cat delete by my local independent

They said one of them was a real pain!

Same here. Except for a bit more track use. Install is complex - done by my dealer

If you could go back, would you get the black ones?

If you could go back in time, would you install the black ones instead of the yellow ones?

Pretty happy with the yellow ones

I'd be curious about the black ones but like the fact there is no extra NVH, don't think I'd want to risk that with the black version

Black! Highly recommend no NVH!

Really wish someone here had a DiY on these.

Not sure I can answer this as I wouldn't know what the black ones feel like and if the NVH would be too much for long distance driving

So there's an earlier thread on these and interestingly someone posted that Powerflex was working with Lotus on a new design. The 2026 notes include revised transmission mounts to improve shifting. I think there is likely some real benefit here if Lotus themselves have taken these folks advice. I'm sure the revised Lotus part will be the whole mount so these inserts seem like a good compromise to get some of that benefit. Id like to see how involved getting to the rear mount is though.

EDIT: Heres the prior thread https://www.emiraforum.com/threads/emira-engine-gearbox-mounts-upgrade.3278/

Good to hear no nvh. I wonder if that holds up over time.
