Transmission clunk

[jimcarden]

I live in Southern Calif. & own a 2006 M45 with 28K miles on it. I have owned the car sense new (about 2 1/2 years). Very recently, the transmission has started to make a rather loud (sometimes REAL LOUD) clunk when it shifts from 2nd into 3rd. This happens for about four or five shift cycles, & then it goes away. It apparantly has something to do with the transmission "warming up" properly?? The dealer is telling me "This is normal."

My questions are: 1. What is causing this?2. Why didn't it do it for the first two years we owned the car?3. Why doesn't my friends M do it as well?4. Why didn't the car we drove at the dealer do it, & or, why weren't we told of this condition?

We are considering selling the car, but who would buy it when it sounds like the transmission is going to blow up any time! I sure wouldn't.

I hope you can help?

Thank you..... Jim C.

PS.. I searched the forum & founf two other floks that has reported this same condition., but didn't see an explanation that made any sense, as I live in a warm climate (not where it's 25 degrees).

Any transmission noise isn't good. I would take into a transmission shop and have them take a look at it.

Hi:

That's probably good advice, the only problem is; my car is still under watrantee, so why should I pay to have something looked & fixed when Infinity should be doing it for me at NC? They are telling me "It's normal." Funny that none of the salesmen at the Infinity dealer has ever heard it on any of thier demo rides...... mmmm? To say the least, I am VERY disapointed in the way that Infinity has handled this matter. At this point I would NEVER buy another product from them if thius is the way they treat thier customers! Hello Cheverolet.

I would go to a different dealer. I know there aren't many out here but I think that's your best option. Especially considering that it sounds like the dealer you're taking it to has no clue.

That is exactly what I intend on doing. I have filed a complaint through Infinity & I'm waiting to hear back from them before I do that. They are supposed to get back to me by tomorrow. Can't wait to hear what they say about this??

Thanks... Jim

PS... Are you an Infinity mechanic?

No I'm not. I am a mechanic but I'm terrible at transmission diagnosis.
