Another 6 speed question
Since my first post went way off topic, I thought I'd ask this question where it might get answered.
I'm pretty sure the light vibrations I feel through the shifter while sitting idle are normal. What I'm not sure is normal is that when I turn on the A/C, the vibrations become much stronger and sometimes feel like a "knock" through the shifter at the frequency of about 2 per second. For those of you with the 6 speed manual that use the A/C, would you mind paying attention for this vibration for a couple of days while sitting at idle with the A/C on after having driven for a while, and let me know something? Thanks!!!!
thanks!
Jim

i've only used the A/C a couple of times so far, however i did not notice any vibration when at idle with the A/C off. but when i turn it on, i do notice some vibration so i'm guessing it's normal.

Jim,
With the manual, youve got a direct link to the drivetrain, youre going to feel a lot of stuff you never did with the auto. Just drive it. THere's always the warranty.

A logical answer could be that Jim has the Delerium Tremens (DT's) now that he, theoritically, got his substance abuse under control, and his hands, etc., are doing the shaking/vibrating.
This is, of course, Opinion only and not a statement of fact.

Naturally you would feel more vibration with the A/C on. Your engine is now running an extra compressor, which could use around 25-30 HP. Thats quite a bit of strain to put on the engine at idle and not have any extra vibration. And like Outland said... There is a direct mechanical link to the engine and shifter in a manual tranny. An automatic has a liquid filled torque convertor that only has a solid link to the engine when the TC lock is turned on, which is usually while cruising above 40-50 mph. Since there is no solid link, the TC acts like a liquid filled vibration isolator, and does it pretty well. Then on top of that, the shifter in and auto is either by a cable or electronic, MB being the latter so you wont get any vibration felt only in the shifter and not the entire car.

Thnaks guy's. I realize I would feel more vibrations w/ A/C on. My main concern is the "knock" (about 2 per second) I'm feeling.

Not sure about your area, but manual MB's are RARE in the southeast.

I suppose this is more pronounced in 2005+ gear box with solid linkages between the stick and the box itself as opposed to the pre-2005 version that has cable links.

AGAIN, I realize you're going to feel vibrations through the stick. I'm concerned about the 2 knocks pers second I feel through the stick sitting at idle, with the A/C on, after you've been driving for a while.

Jim--
I do not feel knocks with AC on, but we have different transmissions. Have it checked at the dealer. And to get peace of mind, try to find another 2005+ MB with a manual tranny (does not have to be a C-Class SS, BTW), and see if it is present.

Do you notice any change in the vibrations through the stick while sitting idle w/ the A/C on and after having driven for a while?
