I am not sure about the problem
But why dont you try this
Resetting Adaptive Transmission
Turn the Key to the "on" position (the position right before you start your engine)
Press and hold your gas pedal down for like 5 seconds
Turn Key to "off" position (dont remove the key) and then release the gas pedal.
Then wait approximately 2 minutes. Your transmission will readjust/relearn your style after approximately 5 minutes of driving
