Transmission Shift Enhancements \- Adaptation Drive Learn Procedure This bulletin involves performing a subjective shift quality rating when customers experience poor shift quality and if necessary, performing the transmission adaptation learn procedure. In addition, this bulletin involves performing transmission adaptation learn procedure when the transmission is repaired/replaced and/or the valve body/TCU assembly \(mechatronic\) is replaced, or when the adaptation memory cells are cleared with the wiTECH diagnostic scan tool. Customers may indicate that their transmission shift quality does not meet their expectations.
