Summary
THIS PRELIMINARY INFORMATION COMMUNICATION PROVIDES INFORMATION TO THE TECHNICIAN THAT SOME OWNERS MAY NOTICE AT ROUGHLY 3/4 OF THE WAY THROUGH THE ACCELERATOR PEDAL TRAVEL THERE IS A CLICK FELT IN THE PEDAL ALSO THE PEDAL GETS HARDER TO PUSH. PLEASE COMMUNICATE TO THE CUSTOMER THIS CONDITION IS A NORMAL OPERATING CHARACTERISTIC OF THEIR VEHICLE. THE ACCELERATOR PEDAL DESIGN HAS CHANGED FOR VEHICLES EQUIPPED WITH THE 8-SPEED AUTOMATIC TRANSMISSION REGULAR PRODUCTION OPTION CODE MRC.
Condition/Concern
Some owners may notice at roughly 3/4 of the way through the accelerator pedal travel there is a detent/click felt in the pedal with increased resistance.
The accelerator pedal design has changed for vehicles equipped with the 8-speed automatic transmission (RPO MRC).
The new accelerator pedal design has a built-in detent position that can be noticed at roughly 3/4 pedal travel.
The detent provides feedback to the operator to minimize transmission downshifting, allowing for improved fuel economy, smoother operation, etc.
Pressing up to the detent will allow a more relaxed acceleration rate.
When pressing through the detent, the transmission will downshift aggressively allowing for an increased acceleration rate.
Recommendation/Instructions
Important: DO NOT replace any parts for this condition.
This is a normal operating characteristic of the vehicle and no repair attempts should be performed.
Customer Information
Please communicate to the customer this condition is a normal operating characteristic of their vehicle. It will not impact the designed performance or reliability of the vehicle. Please share this information with the customer, including a copy of this message.

Date: May-2016
- Backward compatible with previous Dexron automatic transmission fluids and can be used as a much-improved replacement for older vehicles/transmissions originally using previous Dexron fluids
- Improved performance over previous Dexron fluids in: friction durability, viscosity stability, aeration and foam control, and oxidation resistance
- Potential to enable improved fuel economy and longer transmission life
- Provides for extended drain intervals. Provides consistent shift performance, even in extreme conditions.
- For use in 95% of vehicles including most CVTs in operation with US registered light duty applications
- High performance conditioning agents prolong seal elasticity to prevent leaks
- Improved durability & transmission life with anti-wear technology to avoid costly repairs
- Enhanced high & low temp performance supports transmission fluid in all weather situations
- Full synthetic formula with advanced additives protects against transmission breakdown better than conventional fluids

GM bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer”. They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION 1
