Noise from JHM shifter linkage (cross rod) in Audi S4 B7 2007

[automatism]

A JHM cross rod for the gear shifter has been installed in my car but it makes a noise when pressure is applied to the gear stick, any idea what is causing it?

Here is a video of the sound... http://youtu.be/ArD_ziteemI

It makes a slight sound if I apply pressure on the gear shift while it is in gear and I'm driving along. E.g. if I'm in third gear at 3000rpm and I apply a bit of upward pressure, then I hear a slight noise. It is noticeable in the car.

The part...

Pretty sure you should never be doing that while driving....Actually I think it actually says in the manual to not apply pressure to the shifter while the transmission is in gear

I did that in the video to exaggerate the problem. When shifting, there is always pressure applied to get into the gear and I can hear it at that point before releasing the gear shift. Does this happen for your stock shifter? I don't remember this problem with mine.

I would check all of your engine and transmission mounts then. I had some slight noise in my shifter and it turns out my engine and snub mount were toast.

Are you still having this issue? I've had the same noise since cross rod was installed (10 months ago). Thought it could have been 034 (street) trans mount or Apikol snub that were installed at the same time but haven't heard of anyone else having noise issues using these mounts...car was recently torn apart for chain service and noise was exactly the same afterwards.

Yes, it still makes the sound. Let me know if you figure it out.

I have the full JHM linkage and shifter and does the same.

-When short shift installed alone it does the whining noise only when applying pressure on lever while in gear.
-With full linkage it does a bit all the time at low rpm. I have to touch the knob to make it go away.

Factory joints are isolated with plastic and rubber and have high tolerance so vibrations are inexistent. That is the price to pay.
On spirited driving you can't hear it though !

Same here.. ^^^ This is exactly correct... ^^^

There is also a lot of slack in my gear shift ever since it has been fixed. My mechanic said so as well and he's worked on several s4s for comparison. I wonder if I've loosened something with my efforts to try to get the car to go in gear when the cross rod broke. I was able to get it into reverse a couple times but then it stopped doing it (but I didn't stop trying).

I thought the JHM part was supposed to be better. I'd have appreciated known this limitation before the install. I might install the short shifters at some point.

Audi/Vw has billions of dollars; I would think they could design a shifter better then anyone, which they have IMO. The stock shifter is butter, and doesn't look like giant Dong sticking out of the center console like every other car. This is the first car I've not Immediately torn the shifter out of when I got it home. When they designed the factory shifter/linkage they knew it would have to last at least 60,000 miles as well as not cause damage to the transmission during hard shifting. All those rubber's and Isolators on that linkage are there for a reason and I'm pretty sure they pay their engineers many times more then the dudes at JHM. Sorry, I'd never even heard of JHM untill I bought this audi and I've worked on eurotrash professionally now for 5 years; been in the auto repair/tuning business for 15 years total and when the previous owner was all "JHM this and JHM that", I was skeptical to say the least.

Then I saw what they wanted for a downgraded flywheel..Holey sh*t. There's 5 cent's worth of Alu/Steal. So you try and justfy 10,000% markup on material/labor/tooling with "R&D", then I find out they don't even build them!

The only thing I might ever consider is a trans/6th gear from them but even their Core policy is bogus. "If your core needs this and this, then we're adding that to the price of your new one" Suck a cock, if the the things in it weren't worn out I wouldn't be sending it to you.

BUT even with that: I do have full confidence in their trans building skills with these transmissions. partly because they're one of the few shops in existence anymore that will even open one up. From what I have seen they keep it in-house and have a working knowledge of the transmission, more then anyone else I could find.




Ill keep the stocky Shifter =)

JHM markets it as a superior part. I wish I got the last few posts to this thread 3 months ago when the issue happened.

On the plus side, knowing that the sound is due to the part rather than something I've done or something deteriorating is reassuring.

From what I've read, the JHM tune and JHM supercharger is the business for the Audi B7 S4. Only heard good things about JHM. I saved some money getting a MAF sensor from them.

What is with you man? You are always so negative about JHM but say that Audi knows what they were doing when they designed their Eurotrash. (as you call it) You totally contradict yourself all the time. Plus we all can't be extremely cheap with ebay parts and expect our limited production german V8 sedans to last. JHM is the only aftermarket company that supports this platform, remember that.

Have you ever driven an S4 with JHM's short shift kit? I'd bet not, or you'd own one.
