Campaign # 33110 dated: 9/16/2016 status: open

Desc: When a commanded shift occurs outside of the expected transmission turbine speed window limits, the commanded shift monitor requests a driver defaulted 8th gear state. The torque associated with the default action results in broken turbine shaft. The calibration window (based on output speed) for the safety monitor (P16F3) is smaller than the calibration window for the driver initiated tap downshift speed limit checks.

Repair: Reprogram the transmission control module.

So, it sounds like there is a lot of dealer confusion. The reprogram should have been done today and should be all that is needed for vehicles that have not had a failure. Replacement parts and transmission removal should only be needed if the driver is having problems and the shaft has failed.

Guess I will have to call the dealer back to confirm this.

I thought that I would provide an update on this issue:

Went in for a normal oil change and they performed the TCM Reprogram without my requesting it.

My Chevrolet Service Work Receipt identified the work under the 'RECALL CAMPAIGN' section with this wording: Perform Recall 33110 8-Speed Transmission Turbine Shaft Failure. OPEN RECALL. Reprogrammed TCM. Program Code 18F53 Set Up FD8A6.

I did not have a noticeable problem with shifting prior to this work being done. Soon after picking up my V6 Camaro after this software update, the transmission seemed to shift less smoothly, but that smoothed out by the end of a day of driving and has been fine for the past couple of weeks.

Whether the terminology [recall or service bulletin/notice] is correct on this work, the dealerships seem to be instructed to automatically perform this update.
