Sure you’re not pushing the shifter too far to the left (past the resistance) into the area where you would grab reverse? Can’t engage 2nd from there and it will feel as if it’s locked out.

Any updates?

I still have the issue when on track. Not sure what else I can do to address it so will try to do more of my braking in straight line with less trail braking on corner entry.

Stiffer tranny bushings will fix this…tranny is moving under heavy load.

I already have the Rogue Engineering mounts on the car. Anything stiffer is more NVH than I will tolerate on a car that I still drive on the street.

I had started another thread on this topic (forgot to search). I have the exact same problem. I'm also running the Autosolutions SSK, but it sounds like that's not a factor based on the stock shifter folks who also have this issue.

I don't have a better solution so far other than just sticking with 3rd gear. I only needed 2nd in turn 1 at Atlanta Motorsports Park, and after trying that turn both ways, I think staying in 3rd might actually lead to a faster lap time since I don't have to upshift 2>3 before braking into turn 2.

How much more NVH did the mounts create? Compared to the Autosolutions SS?

Hard to say because I added the Turner rear shifter bushing at the same time. I have a noticeable whirring sound but not too bad.

FWIW I added the Autosolutions SSK with 80a bushings and didn't notice any increase in NVH.

I have a little bit of the whirring sound with the autosolutions alone. The shop that does my installs told me to stay away from the trans and engine mounts, but I hate all the slop in the drivetrain!

I did the Rogue trans mounts and Turner shifter bushing at the same time a few weeks ago. Stock shifter otherwise.

Only undesirable changes of note are that the shifter itself moves around a bit more over bumps or in corners, and that I can hear a bit of whirring when the car is in neutral. If I depress the clutch, it goes away.

On the positive side, the shifter feels much more positive and finding the gear I want on track has been easier. Well worth the minimal trade off.

Next up is engine mount inserts. The fluid in the left side mount liberated itself at some point, so I need to replace them anyhow. I went with the ones from Bimmerworld, but Vargas makes them too. I looked for solid rubber mounts, but no luck. I definitely am not going to jump to urethane (the only other option I found) as I still drive too and from the track and on the occasional backroad.

I’m hoping these inserts prolong the life of the hydraulic mounts and stiffen things up just a bit at the same time, without adding too much NVH. Will report back when installed.

Same issues with oem shifter. One time after saving myself from a spin with hard braking, I was stopped and couldn't get the shifter into any gear except reverse. After about 5sec, was able to get into 1st. Sometimes after real hard braking, I can't get into 2nd even just before turn entry, but problem is more consistent while trail braking

Anyone know the problem or solution?

[5.M0NSTER]

So I fixed my issue.

By upgrading to a Camaro SS 1LE. 😝

Sorry, not funny. Huge upgrade in many ways though. That Tremec trans is AWESOME. Thought I’d share.

[alkatraz]

Dammit..

[Daytona_550]

Quick update: spent last weekend at Sebring. I did not have the "finding 2nd gear" problem on Turn 7, where it had popped up for me before. Next event is in December, will update if any news.

How do you like the stock mounts + metal inserts? Noises at idle? One would think the addition of the metal insert would add a lot more noise.

I just purchased the Revshift 95a mounts, but if the stock mount + insert combo is that good I may switch.

There’s enough vibration through the controls under throttle in fast sweepers that I think I want to try something else. A friend found that Powerflex makes urethane inserts. He’ll be installing them soon and if results are good, I’ll probably switch.

When comparing to the M2 CS Racing inserts, the right side mount has a smaller shoulder OD than the left mount insert, whereas the Bimmerworld inserts are the same left to right. So I might also just get the P/S CS Racing insert and switch out the passenger side as well.

TBD until he gets the Powerflex inserts installed. This is mostly a track car for me at this point, so I could live with it, but I want to do something out of sympathy for the car. I would not leave them in a street car.

To document it here:

Just had the Revshift 95a motor mounts installed. These are paired with Rogue trans mounts and Schirmer's diff lift kit with their solid diff bushings.

I have no vibration at idle and it only becomes a minor humm when the AC is on. When I proceed to move in gear, there's heavier vibration (everything will rattle, butt massage, rear view mirror vibrates) from 900-1100 rpm. After 1100rpm, the vibration decreases significantly to a subtle but audible resonance in the cabin where you just hear and feel the motor (it's honestly nice and adds to the whole race car feel). It's definitely dailyable and the only obnoxious thing is the 900-1100 rpm band, but this is just based on my personal tolerance.

On track it could easier to accidentally push the shifter too far left preventing engagement into 2nd.. Give it a try and see if this replicates the feeling.

This. Much easier to do this without realizing it than people think. It happened to me consistently at a track day and befuddled me until I realized what I'd been doing. Easy to get hamfisted when you are white knuckling it through the gears and corners.

I was re-reading this classic R&T article comparing all the 2-series variants and saw the following relevant comment:

"The M2's gearbox is so much better than the 1M's," he says, a sentiment echoed by everybody but me. I'm finding it a pain to come up with second gear in the second-to-last turn, because the reverse detent spring is insufficiently serious about its job.

I know this is an old thread, but same issue here on my 13k mile 2021 M2C this weekend. 3rd to 2nd seemed locked out under lateral load and I'm still on Pilot 4s's....

You're probably moving past the reverse spring detent like I mentioned above.
