Manual Trans. Thud when shifting

[WeinerDog]

I installed the steeda trans bushing insert a couple days ago and haven't had the trans thud since. I need a little bit more time to verify it though.

That is great and I hope it worked for you. But, why would you need more time? I would be able to tell in about 30 seconds. Drive the car and shift up to 4th. If it was gone...:clap2:

Alright guys, here's a bit of a breakdown. I've had the infamous thud since driving it off the lot. I've been able to recreate it at will, whenever I wanted to.

Bought the BMR diff lock out, and the whiteline trans bushing. No changes in the thud. Installed springs and viking shocks no difference.
Changed tranny and diff fluid, no difference.

THEN, to aid in wheelhop and launching ability with my whipple I added BMR's BK054 and their Vertical links.

THE THUD IS GONE. 100% GONE. Seriously.

I drove it about an hour yesterday in various conditions and tried my hardest to recreate it. I think it's the BK054 that did it. The vertical links are a gorgeous piece but I have a hard time seeing how that would solve the thud. I can absolutely see how to BK054 cleans up drivetrain lash, and could/did eliminate the thud.

That sounds like it might work, Steeda also makes a similar kit that is less harsh:

Anybody tried this?

^^^ I have been thinking for quite a while now that it has something to do with suspension/isolation. And that's because I can hear the EXACT sound when hitting just the right bump in the road.

Thanks so much for this info...for $50-$100 bucks I'm all over this.

Please update us on your progress. I would love to hear that these bushing kits can eliminate the thud.

I have just confirmed it. 3 days of driving in different conditions for different periods of time. No thud.

Any increase in other NVH?

That's good to hear. Are these was simple to install as they look? Does the weight of the car need to be off the suspension or can it be left on the ground?

Nvm previous question as I believe I have found the install papers on the site.

There is a slight increase of what I would call ambient noise. Not like a squeeking, or clunking. When you're on a hard road, harsh condition, it's reflected a bit more in the cabin. I'd say if I had to rate the increase in comparison to other cars I've done these sorts of upgrades, I'd rate it a 2/10 increase. It's really minimal but it's there.

I did it on a lift, with the subframe let down a bit. You have to drop it down a little to get the fronts out/in. The rear mounts are a breeze. Whole thing took us about an hour.

You'd probably fight quite a bit to make it work on the ground. Edit: (I don't know that it would even be possible actually)

Thanks for the update. I'll have to see what I can do about getting some of these installed using a lift. I just looked at the instructions and it seems like this would be a pain on the ground.

The part is $50 bucks, I'd for sure pay the extra hour or so of labor time needed to do it on a lift.

But would you say totally worth it to get rid of the THUD? I may try the Steeda kit first but I'd be willing to give up quite a bit of quietness on a harsh road to get rid of that damn sound.

100%. If someone could magically remove the part with zero work or cost, I wouldn't.

No reason to try both. Go right once.

OK, I'm going with the BMR kit. If this works, I'm gonna shout it from the mountain!
