Toyota 30C58200.cuw Transmission Control Calibration
Learn how Toyota calibration 30C58200.cuw relates to 2007 Tundra transmission control and diagnostic code P2714.
30C58200.cuw is a Toyota transmission-control calibration associated with the 2007 Tundra. Toyota service records identify calibration 30C58200 as an updated calibration in bulletins addressing a malfunction indicator light and diagnostic trouble code P2714.
What the calibration controls
The transmission control system manages automatic gear changes by commanding hydraulic pressure and shift components. Code P2714 concerns the performance or operation of a transmission pressure-control solenoid. A problem in this area can affect how hydraulic pressure is regulated and how the transmission shifts.
The calibration provides the control logic and parameters used by the vehicle’s electronic controller. Its role is distinct from the solenoid and other mechanical transmission components that carry out the controller’s commands.
Service bulletin context
Toyota service bulletins TC017-07 and T-TCI-2943 list 30C58200 as an updated calibration for the 2007 Tundra in connection with the malfunction indicator light and P2714. These records connect the calibration to that diagnostic concern, although they do not establish that every occurrence of P2714 has the same cause.
T-SB-0231-10 later lists 30C58200 as a previous calibration. Its vehicle scope includes the 2007 Tundra and 2008 Sequoia, but that multi-vehicle scope does not establish exact fitment for this calibration on every listed model. Any changes described by that later bulletin belong to its subsequent revision, not automatically to 30C58200.
