Since I-€™ve purchased this vehicle I have been having issues with the transmission and engine providing the accurate amount of power as it relates to the acceleration. The persistent issue is the gear shifting lags and rumbles my vehicle each time I accelerate up a hill, accelerating from g20-30mph and it rumbles the gear. I was told the diagnosis was with the spark plugs having an issue on multiple occasions. I-€™ve changed the spark plugs several times along with maintaining everything else within the vehicle. This problem still persist. In 2019 my vehicle stopped on the road and the issue pointed to the computer module. I got the module replaced but the problem still persisted. This is unacceptable and there needs to be an investigation done as my car has shut down due to this issue, lost power in mid-traffic and who knows what else issues this is causing. If there is not proper function in this area then it will be detrimental to the safety of the driver. I also have records of my visits at the dealer as I brought this to their attention but was brushed off as it being a spark plug issue.

Engine began to shudder as if the engine wants to turn off. It can also feel as if there is some issues with the drive axles. It leads to loss of power of the engine. The loss of power goes away upon shutting the engine off and turning it back on however the check engine light remains on and the error code p0420 displays on the reader.

The transmission shudder from bad transmission fluid results in major loss of power and makes it unsafe to turn left on green on green..makes me afraid to pull out knowing it might shudder and not get out of the way in time for city traffic...

Transmission isn't controlled well. When coming to a complete stop the transmission tends to shift to 1st gear violently which may cause the vehicle to move forward and hit a car in front of you. 2018 Camaro 2.0

On or about November 26, 2020, at 1:30 am while driving on I-30 westbound in texarkana, tx traveling at the posted speed of 75 mph in a 2018 Camaro ZL1. The transmission blew out while in cruise control and all systems that transmit power from the engine or propulsion device to the wheels were lost and the vehicle had to coast onto the emergency shoulder until it came to a complete stop away from oncoming traffic. I had contacted Chevy emergency roadside assistance through the vehicles onstar and this service was of no avail. As an alternative I had to utilize triple a in order to have the vehicle towed to orr Chevrolet service department texarkana, tx this vehicle series has the TR6060 transmission is for 6 speed manuals which is manufactured by tremec contains devices and systems that transmit power from the engine or propulsion device to the wheels. Therefore, when shifting between neutral, 1st - 2nd gear and back to neutral encountered numerous events wherein the shifting mechanism grinds and/or drops back into neutral while the vehicle is in motion, with notable fluttering of the shifter and rubbing or friction noise this is associated with the synchronizers. The this is extremely dangerous when pulling in traffic and operating a vehicle in this manner is only a matter of time before a major accident ensues.

Engine cuts out when starting out in 1st gear. Manual transmission. Engine stalled easily. Was rear ended because engine cut out when starting from light and truck behind me drove into me.

Grinding sound coming from the rear end, it does it while turning when the car is cold or sat for a few hours, I'm worried that it's going to lock up some day while traveling. I bought it new and the noise started at about 4000 miles, they changed the fluid and the noise never went away, I try to explain it when I take it in, but they're driving it after it's warmed up, so no noises every time, thanks, and I hear about this from other owners.

Upon downshifting to 2nd gear from 3rd gear is very hard, grinds and pops back in neutral, and fluttering noticed on the shifter with rubbing or friction noise.

The car has a defective transmission housing and the car is hard to downshift or upshift into 2nd gear. The dealers are calling it normal. I have manual 6speed transmission. When I downshift, the shifting liver will either pop right back up into nuteral or grinds.

2018 2.0liter turbo has shifting issues I believe. It is very violent shifting through gears when first start driving and slowing vehicle down, and seems to cause lag when accelerating in everyday driving.
