| Condition | Some customers may comment that the transmission exhibits a harsh 1-2 shift on the first shift of the day, typically under light throttle. | |||||||
| Cause | This condition is due to the initial clutch fill time of the 2-3-4-6-8 (C4) clutch. | |||||||
| Information | Some customers may experience a flare condition on the first 1-2 shift of the day or after the vehicle has been parked for several hours. The condition may have developed after the replacement of a complete transmission assembly or the replacement of the stator support to correct a delayed engagement condition. This is most likely to occur under light throttle conditions. Subsequent 1-2 shifts have acceptable shift feel. Replacing transmission components will not correct the condition. | |||||||
| Correction | Important: Replacing transmission components or complete assemblies will not improve the condition.
The first 1-2 shift of the day may be harsh. The customers’ vehicle should be compared to a like vehicle under the same driving conditions. Do Not replace any parts for this condition. Note: This condition will not impact the designed performance or reliability of the vehicle. |
