Chevrolet Shudder Service Bulletin 16-NA-175

16-NA-175: Shake and/or Shudder During Light Throttle Acceleration Between 25 and 80 MPH (40 and 128 KM/H) at a Steady State – (Oct 11, 2018)

 

Some customers may comment on any of the following conditions:

A shake and/or shudder during light throttle acceleration between 25 and 80 mph (40 and 128 km/h) steady state driving when transmission is not actively shifting gears. A shudder feeling that may be described as driving over rumble strips or rough pavement. Shudder feeling is evident in both Drive and M7 MY15-16 & L7 MY17, MY18 and MY19 mode.

Important: Do NOT replace the torque converter or transmission assembly for this condition. Engineer reviews have proven that replacing the torque converter does not provide a long-term solution to TCC shudder. A revised service procedure will be released in Q1 of 2019. If the vehicle experiences a repeat shudder condition, this document should be followed again. All part replacement claims will be subject to engineering analysis. Any part(s) determined not to be defective will be subject to a possible claim debit.

1. Comments

Chevrolet Colorado owners have experienced significant problems with shudder and hesitation and here are some typical complaints,

“my truck has started randomly doing a quick vibration (fast paced vibration like driving over rumble strips on highway) that typically lasts a second or less.  Sometimes it will do it multiple times over a perioid of several seconds, other times its just a quick vibration.  Its a pretty significant vibration, I really can feel it in the steering wheel and the entire column shakes.   Seems like all interior pieces vibrate as well.”
