Toyota 30C82100.cuw Transmission Control Calibration
Learn how Toyota calibration 30C82100 relates to transmission pressure control and the P2714 service bulletin for the 2008 Tundra.
30C82100.cuw is a Toyota powertrain control calibration associated with automatic transmission pressure control. Toyota lists calibration ID 30C82100 as an updated calibration in a service bulletin for the 2008 Tundra addressing an illuminated malfunction indicator light and diagnostic trouble code P2714.
What the calibration controls
The powertrain control module manages transmission operation alongside engine functions. Its transmission logic commands hydraulic pressure through electronically controlled solenoids, helping the transmission apply clutches and make gear changes. P2714 concerns the performance or stuck-off condition of pressure control solenoid D, so a fault can trigger the warning light and may affect shifting.
Toyota bulletin T-SB-0078-08 identifies 30C82100 as an updated calibration for the documented P2714 condition in the 2008 Tundra. That service context connects this revision to the control strategy involved in the fault. It does not mean that every P2714 code is caused by software or that this calibration repairs a faulty solenoid or other mechanical problem.
How Toyota lists this identifier
In T-SB-0170-09, Toyota lists 30C82100 as a previous calibration within a bulletin covering the 2008 and 2009 Sequoia. The bulletin’s vehicle list describes its overall scope, not necessarily exact fitment for every calibration listed. Any improvement discussed in that bulletin belongs to its updated revision rather than to 30C82100.
The .cuw filename identifies the catalog firmware entry, while 30C82100 is the calibration ID used in the service records. No stock or modified variant label is identified for this entry.
