Toyota 33513000.cuw Transmission Control Calibration
Learn how Toyota calibration 33513000 relates to transmission shift control and the P0770 service bulletin for 2002 vehicles.
33513000.cuw is a Toyota powertrain control calibration associated with automatic transmission shift control. It appears as a previous calibration in Toyota service bulletins addressing diagnostic trouble code P0770, a shift solenoid E malfunction. The controller uses transmission inputs and solenoid commands to manage gear changes, so its calibration affects how the transmission operates during driving.
What P0770 means for this calibration
Shift solenoids control hydraulic circuits that help the automatic transmission select gears. P0770 indicates that the control system has detected a problem associated with shift solenoid E. Toyota bulletin EG025-02 addresses a malfunction indicator light associated with this code. The bulletin covers certain 2002 Toyota 4Runner and Tacoma applications, but that model list does not establish that calibration 33513000 was used in every vehicle covered.
The code identifies the area of the detected fault, not necessarily a failed solenoid by itself. Diagnosis considers the transmission control circuit and the conditions under which the code was set.
Previous calibration in Toyota service records
Toyota lists calibration 33513000 as previous in both EG025-02 and T-TCI-1188. That means it identifies software present before the revision discussed in those bulletins. Any correction described by a bulletin belongs to the updated calibration, not to 33513000 itself.
The .cuw filename carries the same calibration identifier. No stock or modified variant label is specified for this entry, and the service records do not establish additional features for the file.
