| Cause | This condition is a NORMAL characteristic of the transmission, it will not cause durability concerns and no repair attempts should be made. | 
Service Procedure:
At this time this flare condition has been recognized in two different driving conditions:
- During the first 2-3 upshift after the vehicle has been sitting, engine off for several hours. This condition may be caused by air that is trapped in the 3-5-R clutch assembly.When the first 2-3 upshift is made this trapped air is purged and the following 2-3 shifts will be normal with no flare.
When diagnosing this condition a garage shift into reverse before drive will purge this air and prevent the 2-3 flare from occurring. This condition is a NORMAL characteristic of the transmission, it will not cause durability concerns and no repair attempts should be made. 
- When transmission ATF temperature is at or below 85 degrees F (30 degrees C). This 2-3 upshift flare can occur until the ATF temperature warms. If the 2-3 flare is determined to be ATF temperature sensitive use a Tech 2 to make note of the throttle position when the flare occurs. Drive the vehicle to get ATF temperature to at least 104 degrees F (40 degrees C) and then make several 2-3 shifts at the throttle position determined to be the most sensitive to the 2-3 flare. This will allow the transmission adapts to tailor the shifts and may help to eliminate the cold 2-3 flare. This condition is a NORMAL characteristic of the transmission, it will not cause durability concerns and no repair attempts should be made.
Notice: A revised TCM calibration has been released and is available on TIS2WEB to improve this concern in 2007 vehicles equipped with the 6L90 RPO MYD automatic transmission
