My a8 transmission in my 2019 Corvette began to shift irregularly at 6k miles, 10 months. It sounds like it's grinding rocks with quarters. It at the dealership who verified it's the torque converter which has caused �collateral damage�.

Known issues with a sub standard torgue coverter causing a shudder and jerky motion the car starts demonstrating accompanied by fluctuating engine rpms. This Corvette is equipped with a 8i90 8 speed automatic transmission. Its especially noticeable when cruising at highway speed with the cruise control engaged, however it displays this problem whether the cruise control is engaged or not. This issue seems to have affected about 20,000 Corvettes until about the end of October 2016 production dates. Internet research shows tha this is a wide spread problem and there should be a recall on these vehicles that requires gm to replaces the transmission and torque converter.

I had my vehicle serviced at dan vaden Chevrolet in savannah, GA on 16 oct 2017 at (12,200 miles). My main concern was a shudder and jerky motion the car starts demonstrating while in motion, accompanied by fluctuating engine rpms. After researching on the internet there are 1000's of issues with these torque converters and who knows what accidents these failures have caused. There should be a total recall on these transmissions. A service department technician test drove my vehicle and confirmed and documented my concerns and stated it was okay to drive ? I am scheduling another service at (13000 miles). A search of the internet will fill you full of facts on these failures. Problems with the torque converters with these high end vehicles are well on the way to become another Corvette issue of epidemic proportions. Please assist.

While attempting to accelerate or decelerate my car I feel a hesitation, followed by a significant shudder when the vehicle's automatic transmission changes gears. The shudder, shake and hesitation also occurs while my vehicle accelerates in a single gear, and not actively shifting gears. The problem does not merely result in an uncomfortable driving condition. The shuddering and hesitation seem to be related to internal issues within the transmission and/or torque converter causing friction surfaces, hydraulic systems, and gears to not function properly. There is possibly permanent damage that will occur to the transmission and/or torque converter over time. I face escalating repairs that can include flushing the transmission of metal shavings caused by the defective transmission operation, and which eventually necessitate the replacement of components such as the torque converter, valve body, or the entire transmission. As such, the transmission defect endangers the drivers and passengers of the vehicles, and diminishes the value of the vehicles. Gm's deliberate non-disclosure of these defects artificially inflated the purchase and lease price for these vehicles. Gm has known about the transmission defect for years, since right after introduction of the transmission. Since 2015, gm has issued thirteen versions of a �technical service bulletin,� or �TSB,� related to this shifting issue alone. The tsbs related to the transmission issue have advised dealerships to, among other things: complete the �clutch drive learn procedure,� replace the valve body, replace the entire transmission, flush the cooler lines and cooler, remove debris from and clean the transmission pan, replace the transmission filter, replace the transmission fluid, and flush the transmission. To date, none of gm recommended solutions has resolved the problem.

Automatic a8 transmission has the following issues: 1)morning shift from reverse to drive severely delayed, bangs in eventually. 2) erratic shifting in normal traffic 3) the 2-1 downshift when coming to a stop results in severe bang, lurches forward and is very unsafe in a parking lot situation. Also in stop and go traffic, same lurching forward. Feels as if someone hit you from behind 4) torque converter lockup in 5th and 6th gear. Dealer tore apart the car to replace the stator, performed software update - neither solution worked.

2015 Corvette stingray z51 - 8 speed automatic transmission torque converter. With only 7,500 miles on the car it started to run jerky and rpms would fluctuate for no reason (especially at highway speeds when fully warmed up). Often felt like driving on a washboard dirt road. After a cold start, there was a delay after shifting into drive. When it engaged after several seconds it would do so violently, lurching the car forward suddenly. Dealer diagnosed faulty torque converter as defective and a known problem with these transmissions. After less than 2,000 miles the symptoms returned and the dealer again replaced the torque converter. So now I'm on my 3rd defective tc. After 1,700 miles, symptoms returned again! dealer said that Chevrolet and gm have ordered a stop on replacing the tc's since no fix was available. Gm advised to drain and flush tranny, refilling with mobil1 transmission fluid. This seemed to work (only for a little longer) but is worrisome because in the future service, a technician will likely refill with gm fluid, not mobil1. Especially if a second owner. Now at 16,100 miles the symptoms are returning! jerkiness, slamming into gear after a delay on cold starts. Gm seems to have turned their back on stingray owners by kicking the can down the road beyond warrantee (with the mobil1 "band-aid fix"). On the forums there are so many owner complaining about this same issue. I am amazed that there is no official investigation resulting in a recall. This z51 lt3 stingray was $75,000 otd! for this cost we should be able to expect a quality vehicle and a motor company that stands behind it! can somebody please help us with this serious and potentially dangerious problem?.
