CLUTCH VOLUMES - 45RFE/545RFE

The LR clutch volume is updated when doing a manual downshift into 1st gear with vehicle speed above 40 km/h (25 mph) and throttle angle below 5°. The transmission temperature must be above 43 °C (110 °F).

The clutch volume should be between 45 and 134.

NOTE: you must manually move the shift lever into the low position.

The 2C clutch volume is updated when doing a 3-2 shift with throttle angle between 10° and 54°. The transmission temperature must be above 43 °C (110 °F). The clutch volume should be between 25 and 85

The 2CA clutch volume is updated when doing a 4th-4 prime shift with throttle angle between 10° and 54°. The transmission temperature must be above 43 °C (110 °F). The clutch volume should be between 25 and 85

EATX DTC EVENT DATA

EATX DTC EVENT DATA can be used as a diagnostic aid when experiencing Electronic Transmissions with intermittent problems. When a Diagnostic Trouble Code (DTC) is set, the vehicles Transmission inputs are stored in the controller memory and are retrievable with the DRBIII. This information can be helpful when a DTC can not be duplicated.

The EATX DTC EVENT DATA is located in the DRBIII, under the Transmission system menu, in the sub-screen Miscellaneous. It is a good practice to document the EATX DTC EVENT DATA before beginning any diagnostic or service procedure.

A thorough understanding of how the transmission works is beneficial in order to interpret the data correctly. These skills are necessary in order to avoid an incorrect diagnosis.

EATX DTC EVENT DATA can only be erased by:
1. Disconnecting the battery.
2. Performing a DRBIII QUICK LEARN procedure.
3. Reprogramming the EATX controller.

Erasing Transmission DTCs does not clear the EATX DTC EVENT DATA.
