Ryan’s ‘23 A91MT Burnout - Slow Build

[RyanA90]

Ok I've been on a mission to find the right transmission bushings. Here are the ones I've tested.

1. Torque Solutions - 75A durometer bushings

I already reviewed these in my past posts and NVH is high! This was a no for me. These are for the hardcore street/track people.

2. 034 Motor Sport - 60 Durometer (Street Density) Rubber with Void-Free Construction

I couldn't tell the difference between these and OEM. NVH = None to low. OEM equivilent.

3. ECS Polyurethane Transmission Mount Set - Street - 70A Durometer

I just installed these and drove around the block. These are basically the happy medium. NVH= Medium. Not as bad as the Torque Solutions. Shift feel is great, notchier shifts, less play shifting into gears. I tried searching for something that's 65 durometer but failed.

Note: I also looked into powerflex - 70A durometer but the ECS was equivilent and half the price.

Is ecs the one you’ll keep or you going to try more?

What NVH are you experiencing? Hearing more transmission whine?

If I can find something with 65 durometer I'll try it, but I think I'm sticking with ECS for now.

What NVH are you experiencing? Hearing more transmission whine?

Yup similar to Torque solutions NVH but at a lower level. With the windows up and no music, I can hear the clutch engagement, chatter, more of the exhaust note, gear whine.

Do you feel more vibrations through the steering wheel and seat?

On the fence. I got a shift kit, rear carrier and shifter bushing, so the shifting action feel much better, but still some really tiny slop. Wondering if I should leave it or chase perfection...

Short shifter kit? I wouldn't say it vibrates the seats or the wheel. Its more like the mechanical sounds are amplified through the shifter and ultimately the cabin.

Ok I drove to work today. Here are more thoughts.

1. Reverse-1st-2nd-3rd gears have the loudest gear whines in that order, but progressively disappear. I'm assuming those are the largest gears in diameter so they tend to make more noise?

2. Slight vibrations from the floorboard and steering wheel but nothing crazy.

3. Exhaust rumble is more audible in cabin, I love it!

These might also be relative to the mods you have.

I'm keeping these on. With music on, all the noise gets drowned out and doesn't bother me.

Edit: The above statements pertain to normal driving. WOT will rattle out your teeth out I’ll be switching back to the 034 motorsports bushings.

I went to install the canbus harness and there isn’t a 12v source near the DME that I know of for power and I don’t feel like extending the wire to reach the fuse box. So I ended up ordering this Universal accessory harness to make it work. I’ll finally be able to get tuned for flex fuel https://burgertuning.com/products/b...xkYnXmagxbemyXgCFMr6CK266D3fjtud9C4ILN67YdJ0q

Did you install the low fuel pressure sensor too or just the universal harness?

I have the Fuel It Flex Fuel bluetooth sensor, so I think rather than get the MHD Flex Fuel kit, I can go the same route as you.

Just the universal harness.

Just got done installing the Rogue Engineering F8X/G8X Shifter Bushing Kit. Highly recommended.

Installation in my garage, on my back took about 2.5 hours max. I did not remove my exhaust, but I loosened the back half so that I could twist and maneuver the tunnel cover out of the way as much as I can.

I didn't remove the driveshaft.
I did have to lower the tranny a bit for extra room.

Shifter Feel & Performance

• Significantly Tighter Action: Eliminates side-to-side slop and the soft, "rubbery" OEM vagueness, providing a notably crisper, more mechanical engagement into each gear.
• Retains OEM Throw Length: Improves shift precision and gate feedback without making the shifts excessively heavy.
• No added NVH

This bushing kit delivers the "tight mechanical feel" the car should have had from the factory.

One of my favorite mods I’ve done. Carrier bushings a huge must imo. I think the oem shifter is great for new manual users.

But it always felt like I was gonna break something when shifting.

I agree! This tightens everything up, feels way more solid, and no more slop/play in any gear.
