P1736-GEAR RATIO ERROR IN 2ND PRIME
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Continuously with the ignition on, engine running, with the transmissionin gear.

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 transmission system uses two speed sensors, one to measure input RPM and one to measure output RPM.
These inputs are essential for proper transmission operation. Therefore, the integrity of this data is verified through
the following checks:
1) When in gear, if the gear ratio does not compare to a known gear ratio, the corresponding in-gear trouble code
is set (DTCs P0731-36).
2) An excessive change in input or output speeds indicating signal intermittent which may result in the DTCs P0715
and/or P0720 to set.
3) If the common speed sensor ground circuit is lost, both sensor inputs will read the signal from the input speed
sensor at idle in neutral. Since the input speed sensor reads 60 teeth from the input clutch hub and the output
speed sensor reads 30 teeth from the park gear, the result is an apparent speed ratio of 1:2 and may cause the
DTC P1794 to set when at a stop.

P1790-FAULT IMMEDIATELY AFTER SHIFT
For a complete wiring diagramRefer to Section 8W
When Monitored:
After a speed ratio error is stored.
Set Condition:
This DTC is set if the associated speed ratio DTC is stored within 1.3 seconds after a shift.
Possible Causes
FAULT AFTER SHIFT
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
This DTC will only be stored along with a gear ratio DTC. If this DTC is set, itindicates a probable hydraulic (line
pressure) or mechanical problem exists. Diagnosing the transmission should be based on the associated speed
ratio DTC and mechanical causes should be considered first.

With the scan tool, check the DTC EVENT DATA to determine in which gear the slippage occurred and the clutches
that were applied.

Repair
Refer to the Transmission category and perform the appropriate symptom identified from the DTC
EVENT DATA, intended gear, and applied clutches.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21- TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)

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.
