- [PI1154](/bulletins/10191013.md), 2021-04-28, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION. Delayed 1\-2 Upshift While Driving at or Below 15 Percent Throttle Condition/Concern Some customers may comment that during the first few launches after a key cycle, they experience a delayed 1\-2 upshift. If the vehicle has no diagnostic codes, the delay in the 1\-2 shift may be driver induced. If the vehicle has diagnostic codes, address these diagnostic codes prior to using this bulletin. On a level surface if the vehicle is launched from a stop at light throttle \(less than 15%\), then the throttle is closed before reaching 16 km/h \(10 mph\), then the throttle is opened and held to less than 15%, there could be a 1\-2 upshift delay. This delay will last until the vehicle exceeds 24 km/h \(15 mph\) or the driver drops back to closed throttle.
