Owners of the Chevrolet Colorado and other models have been  complaining about hesitation and shifting issues on GM 8 speed vehicles.  The vehicles are equipped with GM 8L45 or 8L90 automatic transmissions that hesitate when drivers accelerate or decelerate. Drivers complain the transmissions can shift so hard it feels its almost like being hit by another vehicle.

According to the lawsuit, each fix offered by the automaker has allegedly failed to repair the shaking, shuddering and jerking, and the plaintiffs claim both the torque converters and transmissions cause problems with the hydraulic systems and gears.

  According to the lawsuit, each fix offered by the automaker has allegedly failed to repair the shaking, shuddering and jerking, and the plaintiffs claim both the torque converters and transmissions cause problems with the hydraulic systems and gears.  Despite complaints, GM has not recalled the vehicle for this problem, nor has the NHTSA ordered a recall.  Instead the company has issued a service bulletin  Chevrolet Shudder Service Bulletin 16-NA-175.

  That provides for new transmission fluid, and other changes, which seems to have limited benefit for many owners.
