Theory of Operation
The Solenoid Switch Valve, an internal, hydraulically operated valve, controls the direction of the transmission fluid
when the LR solenoid is energized. When the solenoid switch valve is in the downshifted position and the LR sole-
noid is energized, fluid is directed to the LR element for 1st gear. When thesolenoid switch valve is In the up-
shifted position (2nd, 3rd, and 4th gear) and the LR solenoid is energized,fluidisdirectedintotheLockupSwitch
Valve which controls the Torque Converter Clutch. When shifting into 1st gear, a special sequence is followed to
insure solenoid switch valve movement into the downshifted position. TheLR pressure switch is monitored to con-
firm switch valve movement. If the solenoid switch valve movement is not confirmed (i.e. no LR pressure when the
LR solenoid is energized), 2nd gear is substituted for 1st. No 1st gear (2ndgear is substituted). The transmission
Torque converter FEMCC operation is inhibited. MIL on after 5 min. of substituted operation.

Theory of Operation
The Solenoid Switch Valve, an internal, hydraulically operated valve, controls the direction of the transmission fluid
when the L/R solenoid is energized. When the solenoid switch valve is in thedownshifted position and the L/R
solenoid is energized, fluid is directed to the L/R element for 1st gear. When the solenoid switch valve is In the
up-shifted position (2nd, 3rd, and 4th gear) and the L/R solenoid is energized, fluid is directed into the Lockup
Switch Valve which controls the Torque Converter Clutch. When doing PEMCCor FEMCC, the L/R pressure switch
should indicate no pressure if the solenoid switch valve is in the L/R position. If the L/R pressure switch indicates
pressure for some time while in partial or full EMCC, the EMCC operation is aborted and momentarily inhibited to
avoid accidental application of the L/R clutch. EMCC is attempted again when there is no L/R pressure. The fourth
detection of L/R pressure while in PEMCC or FEMCC will result in setting theDTC. Torque converter EMCC oper-
ation inhibited. MIL on after 5 min. of substituted operation.

When Monitored:
Every 7msec after a controller reset with transmission in neutral.
Set Condition:
After a PCM reset in neutral and Input and Output sensor ratio equals 2.50 to1.0 ± 50.0 RPM.
Possible Causes
SPEED SENSOR GROUND CIRCUIT OPEN
POWERTRAIN CONTROL MODULE
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The input and output speed sensors use a common ground circuit. The loss of this common ground results in the
input signal being sensed for both. After a reset in neutral, and after observing a specific ratio, the Speed Check
Fault Counter will increment. Because the speed sensors and the thermistor share the same ground circuit, this
DTC may indicate a loss of the common speed sensor ground. In some cases thisfault will cause a Gear Ratio
Error DTC to be set.
