Need help with my Corvette
I have a 2016 Z51 M7. I took it to mutiple GM worthless mechanics for issues involving grinding when shifting from 1-2 2-3. First thing they did was replace the clutch. Now a year later I have grinding in all the gears. I'm hearing a click sound and werid vibration sounds when I'm driving on the highways that goes away when I slam the gas. Now the biggest issue I am noticing is that I can feeling some bad back and forth motions if I'm in first and give it gas an let go of the gas. Also downshift is the worse. Driving around parking lots is painful because it is terrible. Can anyone give me advice. I'm done with GM mechanics. They all suck IMHO.
Very Respectfully,
Derek

Have you tried to realign the shifter box? There is a TSB on it:

I'd try to find someone experienced with transmissions. Corvette/sports car shop if possible.
I'm guessing GM products in Russia are fairly uncommon so mechanics don't have much experience with them. Parts may be hard to get too.
There are bound to be some speed shops around.
Good luck

Buy a used M7 transmission in working order. Have a shop install the transmission for you. This all gets your car back on the road as soon as possible.
Take the broken one home, dissemble and inspect it on your own. Make a project out of it. Build or buy special tools as needed. Then you'll know about the M7 transmission and one of the ways it goes bad. Source replacement parts and repair it. Not only will you have a spare but you'll be an M7 expert and probably know what you're hearing the next time one acts up.

Derek... people here are just trying to help you with your issue, and that in an environment where your car cannot be all that common (heck, there are no others in the town I live in here in the States). Lighten-up. And, all the best fixing your Vette.
