2004-2007 Cadillac CTS-V General Discussion Discussion, Clunk when slowing down in 3rd in Cadillac CTS-V Series Forum - 2004 - 2007; When i brake in 3rd gear and it gets to around 1500 rpms, there is a clunk noise. It sounds ...
That's a pretty vague question to answer. Search and read some of the previous discussions. There are a lot of things that can clunk in this car.
If you want more help identifying your specific issue we're going to need more information.
Where does it sound like it is coming from?
Is it right when you let off the gas?
Is it really only in 3rd gear, or is that just when you happen to notice? A specific gear would indicate the transmission.
What is the condition of your car? mileage? track days? autox? all stock?
As a shot in the dark. If you have motor mounts or differential bushings with more than 20k miles on them they probably need to be replaced.
ya sorry for the vagueness. It's definitely drivetrain related. I've 150k miles on the car, but the transmission is almost brand new on the inside. I just got it out of the shop yesterday for a broken synchro. the synchro was brand new too when it broke. i'm sick of taking it in, even though they cover it with warrantee because its my DD. And i haven't noticed the clunk except in 3rd gear and slowing down. the clunk kind of sounds/feels like if you were to just pull it out of gear without the clutch, it makes a clunk, and the car jerked. i felt it when i went to work this morning, and then when i went for lunch.
well, its been in and out of the trans shop 2wice. Both times they had it for over a month. they are tough to work with and its all i've got because they cover the warrantee. I could easily take it back and have them pull it all apart again, but if anyone on here didn't think it was necessarily transmission related, i'd like to try and do something myself first. Sometimes free just isn't worth the hassle.
