Sometimes when I'm in bed at night I think I can hear the car whispering to me from the garage but I don't think it's a mechanical issue either.

My 2016 track pack has a very noticeable clunk when shitting down. Seems to run fine though. 29,000 miles on the car now.

What's with the Shitting stuff? LOL :shrug::shrug:Wow thank you for the help guys. This forum is so difffent from all the other forums I’ve been a member to. You guys are so helpful. This makes me feel better about the car. As far as shutting down the vehicle goes, I turn the valves to closed mode and shit the car off with the clutch in but still makes the thump sound. But don’t care since it seems like it’s a normal thing. And it also explains a lot that our clutch is a little louder than most since it’s a twin disk.
That's me... :love:Sometimes when I'm in bed at night I think I can hear the car whispering to me from the garage but I don't think it's a mechanical issue either.
That's good to hear. I feel like my gears are slowly getting smoother as well.Not aware of the noise, but shifting was clunky when I first got the car. Now have a little over 1,000 miles, and the shift action has improved. I hope it continues to the level my Z/28 was.....that particular Tremec and shifter were absolute silk.
thank you for your detailed response.Noise is from the dual mass flywheel on shutdown absolutely normal!
Thank god

Dual-mass flywheel section
A dual-mass flywheel or DMF is a rotating mechanical device that is used to provide continuous energy (rotational energy) in systems where the energy source is not continuous, the same way as a conventional flywheel acts, but damping any violent variation of torque or revolutions that could cause an unwanted vibration. The vibration reduction is achieved by accumulating stored energy in the two flywheel half masses over a period of time but damped by a series of strong springs, doing that at a rate that is compatible with the energy source, and then releasing that energy at a much higher rate over a relatively short time. A compact dual-mass flywheel often includes the whole clutch, including the pressure plate and the friction disc.[1]

History[edit]
https://en.wikipedia.org/wiki/File:Torque_Converter_Centrifugal_Pendulum_Absorber.png
Schaeffler torque converter with a pendulum absorber using the same DMF's bent springs.
Dual-mass flywheels were developed to address the escalation of torque and power, especially at low revs. The growing concern for the environment and the adoption of more stringent regulations have marked the development of more efficient new engines, lowering the cylinder number to 3 or even 2 cylinders, and allowing the delivery of more torque and power at low revolutions. The counterpart has been an increase in the level of vibration which traditional clutch discs are unable to absorb. This is where the dual-mass flywheels play a key role, making these mechanical developments more viable.[2]
The absorption capacity of the vibration depends on the moving parts of the DMF, these parts are subject to wear. Whenever the clutch is replaced, the DMF should be checked for wear. The two key wear characteristics are freeplay and sideplay (rock). These should be measured to determine whether the flywheel is serviceable. The wear limit specifications can be found in vehicle or flywheel manufacturer's published documentation. Other failure modes are severely grooved/damaged clutch mating surface, grease loss, and cracking.[2]
LOLLLLLLLLLLL typos I didn't even know i wrote that :headbonk:What's with the Shitting stuff? LOL :shrug::shrug:
When I first got my 2017 GT350 (16.6 miles on the ODO) the shifter was quite notchy, it was difficult downshifting from 3rd to 2nd, but it loosened up nicely as the miles packed on. Mine shifts great now. (6,700 miles)
Yea I slowly see it getting smoother. I did have to break it in! I'm enjoying it way more knowing that nothing is wrongBecause of the higher torque capacity, Tremec originally designed the 3160 trans for truck applications, but they also made it modular to offer a few options for gear ratios with single or double overdrive. As far as I know this has only been offered in some Cadillacs, Camaro and GT350, but has some of the latest manual technology.
These definitely get better the more miles are put on the car.
