- Correction
-
Some customers may comment on a sag or hesitation when accelerating under the following conditions:
When coasting at low speeds of less than 15 miles per hour with a closed throttle and then aggressively applying the throttle.
Examples of this maneuver include a rolling stop or a lane change maneuver. In this type of maneuver, even though the accelerator is applied aggressively, the throttle blade is opened slowly for up to 0.7 seconds to help minimize drive-line lash and clunking.
Also in a vehicle equipped with a six speed automatic transmission when making a hard, complete stop with a closed throttle, immediately followed by an aggressive throttle opening the transmission down-shifts may not be completed by the time the throttle is opened.
As a result approximately 0.5 seconds of ″zero″ torque may be commanded to allow the shift to first gear to occur.
Recommendations / InstructionsBoth of the above conditions are a result of Torque Management and both of these conditions should be considered normal and no repairs should be attempted.
Please follow this diagnostic or repair process thoroughly and complete each step.
If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
