Toyota 30C60000.cuw Transmission Control Calibration
Learn how Toyota 30C60000.cuw relates to 2007 Tundra transmission control and service bulletins addressing P2714.
30C60000.cuw is a Toyota transmission control calibration associated with the 2007 Tundra. Toyota service records list calibration ID 30C60000 as a previous calibration in bulletins addressing an illuminated malfunction indicator light and diagnostic trouble code P2714.
The transmission control software helps the powertrain controller manage automatic transmission operation. It uses operating conditions to command shift timing and transmission hydraulic pressure. Those commands affect how the transmission engages gears and responds as the vehicle is driven.
What P2714 means for this calibration
P2714 concerns the performance of a transmission pressure control solenoid. That solenoid helps regulate hydraulic pressure used in transmission operation. When the controller detects a condition that meets its diagnostic criteria, it can store the code and illuminate the malfunction indicator light.
Toyota bulletins TC017-07 and T-TCI-2943 both identify 30C60000 as a previous calibration for the documented P2714 warning-light condition on the 2007 Tundra. The bulletins discuss a later revision in that context. The association does not establish that the previous calibration itself contains the revision’s changes.
The presence of this calibration and code is useful service information, but P2714 alone does not identify the cause of a particular vehicle’s fault. Diagnosis still needs to consider the transmission control system and the vehicle’s condition.
