My 2007 GT w/ TR-3650 has just under 20k miles (bought new in 2006). I noticed this year that the shifter makes a harsh clunk/cracking sound during takeoff from 1st gear (just an easy take-off, like pulling away from a stop sign while turning, etc...) and 2nd gear. If I jab the brakes hard, the shifter will make that same clunk especially in the 1-3 gears but it does it in 5th as well. It doesn't seem to do it as much or at all in 2nd and 4th gear.
I did some experimentation and if I shift into neutral while at speed (say 40-50 mph), it will still make that clunk/crack. If the car is moving in reverse, it does it as well in neutral. It also makes the sound when I have the clutch pedal depressed under the same conditions.
Here's the history of the car:
Kept the stock shifter up until 2015, when I switched to the Hurst Billet
Kept the stock H-pipes up until 2015, switched to Pypes off-road X, switched back to stock H-pipe earlier this year. All pipe connections are tight.
Swapped from stock axle-backs to FR500S/GT500KR mufflers in 2012.
Swapped from stock rear lower control arms to Steeda Billet sometime in 2012 as well.
The TR-3650 always had rattling, but not this clunk and I don't recall it ever doing it until early this year.
The clunk/cracking sound seems to only occur when there is a sudden shift in the chassis, like accelerating or hard braking.
If I'm on the freeway driving normally, the shifter feels tight and there are no odd noises. The clutch works fine, as does the transmission.
It feels almost as if the shifter is being yanked forward (towards the engine) during hard braking, and during accelerating from a stop, the same thing is occurring. I did a test by resting my hand on the shifter (gently) to try and feel the cracking sound, and it seems like something is yanking the trans - even in neutral and w/ the clutch disengaged.
Before I spend hours just checking every single bolt, I wanted to know if anyone encountered this? I didn't want to mention the Hurst up front because there are numerous complaints about harsh/notchy shifting, rattling, etc... and I'm used to that. But this cracking/clunking sound isn't normal to me.
