Toyota 30C59200.cuw Transmission Control Calibration
Learn how Toyota calibration 30C59200 relates to a 2007 Tundra transmission warning and diagnostic code P2714.
30C59200.cuw is a Toyota powertrain control calibration associated with automatic transmission control. Toyota service records identify 30C59200 as an updated calibration for a 2007 Tundra bulletin addressing an illuminated malfunction indicator light and diagnostic trouble code P2714.
P2714 concerns the performance or operation of a transmission pressure control solenoid. The control system uses solenoids to regulate hydraulic pressure for gear changes. A fault detected in that system can turn on the check-engine light and store a code for diagnosis.
What the Tundra bulletin addresses
Toyota service bulletins TC017-07 and T-TCI-2943 list 30C59200 as the updated calibration for the P2714 warning condition. This places the calibration in the context of the transmission-control response to that diagnostic issue. The records do not establish the precise software changes or show that every P2714 fault has the same cause.
In practical terms, the warning tells a technician to investigate a transmission pressure-control condition. The calibration is part of the control and diagnostic context, while the stored code remains a starting point for determining the cause.
