2. WHAT CAUSES THE CHEVY SHAKE?

The class action lawsuits named two causes for the Chevy Shake: a weak aluminum driveshaft and GM’s 8L90 and 8L45 transmissions.

According to Kim Bostick v. General Motors, the aluminum driveshaft (known as a “propeller shaft” or “prop shaft”) weakens over time and eventually drops to the ground. The “prop shaft” is supposed to transfer power from the engine to the wheels, but when it falls apart, the vehicle becomes undriveable.

According to Francis v. General Motors, the problem is caused by faulty 8-speed transmissions and/or torque converters. The hydraulic systems and gears don’t work properly because of internal issues in the 8L45 and 8L90 transmissions. The 8-speed transmissions and/or torque converters cause friction between surfaces. As a result, metal shavings circulate throughout the transmission, damaging components and leading to transmission failure.

According to Battle v. General Motors, the Hydra-Matic 8L45 and 8L90 transmissions have a “shift defect” that General Motors has not fixed. General Motors allegedly knew about the Chevy Shake shift defect since 2013, but will not fix it until 2023 with a major redesign of the transmission.

3. HAS GENERAL MOTORS FIXED THE CHEVY SHAKE?

No. To date, General Motors hasn’t provided an adequate fix.

General Motors knew about the defect with the Chevy Shake since at least 2013. When GM tested a vehicle with one of these 8-speed transmissions, the downshift was described as a “neck snapper.” Since 2015, General Motors issued at least 13 versions of a technical service bulletin. This TSB advised the dealerships to attempt these repairs:

• The “clutch drive learn procedure”
• Replace the valve body
• Flush the cooler and cooler lines
• Flush the transmission
• Remove debris from and clean the transmission pan
• Replace the transmission filter
• Replace the transmission fluid
• Replace the transmission entirely

At one point, General Motors even considered a service proposal to include valve body replacements on the 8L45 and 8L90 transmissions at $1,250, according to a class action lawsuit.

Drivers with aluminum driveshafts have had to pay for custom steel driveshafts out of pocket. Some drivers got their transmissions flushed to deal with metal shavings caused by the defect. According to one lawsuit, drivers may require replacements of the torque converter, valve body or entire transmission.

When drivers dealing with the Chevy Shake do get replacements, they receive equally defective replacement parts.

In short, General Motors left the consumers to solve the problem with the faulty driveshaft, and allegedly doesn’t plan to fix the 8-speed transmission until at least 2023.

4. HOW DO I KNOW IF MY CADILLAC, CHEVY OR GMC VEHICLE IS A LEMON?

Your Cadillac, Chevrolet or GMC may have the Chevy Shake defect if the dealership can’t seem to fix any of these issues in your vehicle:

• Shaking and shuddering
• Vehicle jerking
• Vehicle hesitation
• Harsh or delayed shifting
• Harsh engagement
• Clunks while shifting
• Transmission slipping
• Difficulty stopping

Many drivers have reported that these defects ultimately led to transmission failure or the vehicle becoming undriveable. Of course, vehicles with the Chevy Shake defect can have other problems that won’t go away, making the vehicles unsafe to drive.

Cadillac, Chevy and GMC “Chevy Shake” Complaints

The Chevy Shake class action lawsuits show that many Cadillac, Chevrolet and GMC drivers sent complaints to federal regulators about the Chevy Shake defect. Read these complaints submitted to the National Highway Traffic Safety Administration.

Chevy Silverado Can’t Find Gears

“Transmission cannot find gears when coasting or slowing down and then hitting accelerator. Very dangerous when it hesitates for seconds before finding the right gear and going, or it stays in too high of a gear instead of downshifting to accelerate and rattles. Happens every time I drive the truck, and many other people have the same issue. GM doesn’t care!”

Chevy Torque Converter Locks Up

“The torque converter was locking up on random occasions with no warning before shifting period. [It was] very dangerous while in traffic or trying to turn. GM told me they know about this problem of course and said [to] install a new transmission with updated parts that were bad from the factory.”

Chevy Corvette Shifts Erratically

“8-speed automatic transmission always shifts erratically when starting out cold (lazy shift, slow shift, etc.) and occasionally does not downshift when car comes to a stop, only to slam hard into 1st when gas pedal is pressed to resume travel. Dealer says GM claims this is “normal,” but no car I’ve ever owned behaves like this. Appears to be fluid starvation internally.”

GMC Nearly Goes Through Garage Door

“Truck shifts really hard and is unpredictable. I almost drove through my garage door the other day shifting to drive from reverse. Truck will lunge forward or delay in shifting. There have been a few times I’ve had to slam on the brakes before I backed into something. I have brought it in 3-4 times for the issue and GMC won’t remedy the problem.”
