Transmission "clunk"
Today I heard the first strange noise out of my car. At idle it will make an occasional "clunk" noise, about every 10 seconds or so. CLutch engages smoothly, holds great, shifts smooth, and doesnt make a peep at anything over 1200 rpm's. Any ideas?
I am going to call my pals at rps and have them start putting together a triple carbon clutch for this thing in anticipation of the clutch shooting craps. |

It's an easy fix if so. Also, is the CAGs solenoid disconnected?

Re: Transmission "clunk"
Does your car have any kind of miss, could be the dual mass flywheel.

 > I haven't really had a lot of time to dedicate to the car yet as I am still finishing up three other builds I started before I got her.It idles arouns 900 rpms, unless I am coming down from speed then it hangs aroun 1200, and drops a few seconds later back to ~900. The guy that had it before me wasn't exactly honest with me when he sold the car, but I figure sooner or later I will have the time to dive into it and pinpoint all the issues. In the mean time, I may as well make use of the years of experience on the forums to help me get a running start

Re: Transmission "clunk"
I would say get the "lope" fixed before doing anything else. I think that's causing a clunking in the DMF. Very common for these Beasts. 900 is pretty high for a stocker, I think you're dead on with the vacumm leak.

Anyway this lockout when going in and out can make a clunk. The CAGs is located on the drivers side of the tranny. You can check the C beam bolts while under there.
