P2700-INADEQUATE ELEMENT VOLUME LR
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Whenever the engine is running. The LR clutch volume index (CVI) is updatedduring a 3-1 or 2-1 manual
downshift with throttle angle below 5 degrees. Transmission temperaturemust be at least 43° C (110° F).
Set Condition:
When the LR clutch volume index (CVI) falls below 16.
Possible Causes
HYDRAULIC LEAK IN THE VALVE BODY
BROKEN L/R CLUTCH PISTON RETURN SPRING OR SPRING RETAINERS
BROKEN L/R ACCUMULATOR SPRING(S)
TRANSMISSION SOLENOID/TRS ASSEMBLY
POWERTRAIN CONTROL MODULE
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The volumes of the transmission fluid needed to apply the friction elements are continuously monitored and learned
for adaptive controls. As the clutch friction material wears, the volume of fluid needed to apply the clutch increases.
Certain transmission mechanical problems can cause near-zero learned volumes resulting in setting a DTC. The
DTC will usually set with other DTC’s, which indicates an internal transmission problem.
