6.CHECK TO SEE IF DTC P1736 IS CURRENT
With the scan tool, perform the 2nd Prime Gear Clutch Test. Follow the instructions on the scan tool.
Increase the throttle angle, TPS Degree, to 30° for no more than a few seconds.
CAUTION: Do not overheat the transmission.
NOTE: If the 4C clutch is faulty, the overrunning clutch will hold and the slip test will pass. The 2nd Prime
Gear Clutch Test will not detect a faulty 4C clutch. However, it will detectafaultyUDclutch.

When Monitored:
During an attempted shift into 1st gear.
Set Condition:
This DTC is set if three unsuccessful attempts are made to shift the SolenoidSwitchValve(SSV)intothe
downshiftedpositioninonegivenignitionstart.ThisDTCcantakeuptofive minutes to mature before illumi-
nating the MIL.
Possible Causes

SOLENOID SWITCH VALVE STICKING
L/R PRESSURE SWITCH SENSE CIRCUIT SHORT TO OTHER CIRCUITS
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 Solenoid Switch Valve (SSV) controls the direction of the transmission fluid when the L/R Solenoid is energized.
The SSV will be in the downshifted position in 1st gear, thus directing the fluid to the L/R clutch circuit. In 2nd
through 5th gears, it will be in the upshifted position and directing the fluid into the torque converter clutch (TCC).
When shifting into 1st gear, a special hydraulic sequence is performed to ensure SSV movement into the down-
shifted position. The L/R Pressure Switch is monitored to confirm SSV movement. If movement is not confirmed (the
L/R pressure switch does not close), EMCC is inhibited until SSV operationis confirmed.

Set Condition:

problem identification before illuminating the MIL.

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 Solenoid Switch Valve (SSV) controls the direction of the transmission fluid when the L/R Solenoid is energized.
The SSV will be in the downshifted position in 1st gear, thus directing the fluid to the L/R clutch circuit. In 2nd
through 5th gears, it will be in the upshifted position and directing the fluid into the torque converter clutch (TCC).
When in 2nd, 2nd Prime, 3rd, 4th, or 5th gear, the Torque Converter Clutch (TCC) can be engaged when certain
conditions are met. The TCC piston is electronically modulated by increasing the duty cycle of the L/R solenoid until
the torque converter slip difference (difference between engine and transmission input speed) is within 60 RPM.
Then the L/R solenoid isfully energized (FEMCC - 100% duty cycle). Torque converter slip is monitored in FEMCC
to ensure adequate clutch capacity.

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.

Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21- TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)

When Monitored:
The gear ratio is monitored continuously while the Transmission is in gear.
Set Condition:
After a controller reset in neutral and a ratio of input to output, of 1 to 2. ThisDTCcantakeuptofiveminutes
of problem identification before illuminating the MIL.
Possible Causes
(T13) SPEED SENSOR GROUND CIRCUIT OPEN
(T13) SPEED SENSOR GROUND CIRCUIT SHORT TO GROUND
(T13) SPEED SENSOR GROUND CIRCUIT SHORT TO VOLTAGE
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 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.
Diagnostic Test

WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in
personal injury or death.

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.
