ever they are removed. The straps slightly deform
when torqued in place. Reuse of the straps may
result in reduced clamp load on the universal joint
cap.

2. Install case and bolt together using all bolts.
3. Rotate countershaft to seat bearings.
4. Screw Stud 8161 into the case and set up dial indi-
cator (1) on the countershaft (2).
5. Zero dial indicator and record end play. If there is
no end play, install .010 in. thinner shim until an
end play is obtained.
6. Once an end play reading is obtained, add end
play number to the shims in the transmission.

REMOVAL
NOTE: If input shaft is damaged behind the seal,
the transmission must be disassembled and
inspected.
1. Remove transmission from the vehicle.
2. Measure output shaft end play and record number.
3. Remove clutch slave cylinder from transmission
adapter plate.
4. Remove front adapter plate bolts (1).
5. Pry front cover adapter loose.
6. Hold input shaft while removing adapter (2).
7. Remove sealant from transmission adapter.
8. Clean and inspect all sealing surfaces for wear or
damage.
9. Lift counter shaft slightly and remove input shaft (2)
from transmission (1).

P0731-GEAR RATIO ERROR IN 1ST
For a complete wiring diagramRefer to Section 8W.
When Monitored:
The Transmission gear ratio is monitored continuously while the transmission is in gear.
Set Condition:
If the ratio of the Input RPM to the Output RPM does not match the current gearratio when compared to the
known gear ratio.
Possible Causes
RELATED TRANSMISSION DTCS PRESENT
INTERMITTENT GEAR RATIO ERRORS
INTERNAL TRANSMISSION
Always perform the 42RLE Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - 42RLE - 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
data checks. When in gear, if the gear ratio does not compare to a known gear ratio, the corresponding gear ratio
error trouble code is set. The transmission will go into Limp-in mode afterfour gear ratio error events occur in a
given driving cycle.
Diagnostic Test
1.DETERMINING IF RELATED TRANSMISSION DTCS ARE PRESENT
With the scan tool, read Transmission DTCs.
If any of these DTCs are present, perform their respective tests first.
Are there any Loss of Prime, Line Pressure Sensor and/or Speed Sensor DTCs present?
Ye s>>
Refer to appropriate diagnostic procedure in the Transmission category.If any of these DTC’s are
present, they will cause a gear ratio error. Perform the test for Loss of Primefirstifitispresent.
No>>
Go To 2
2.CHECK TO SEE IF P0731 IS CURRENT
With the scan tool, perform the 1st gear clutch test. Follow the instructions on the scan tool.
Increase the throttle angle or TPS Degree to 30° for no more than a few seconds.
CAUTION: Do not overheat the transmission.
Did the Clutch Test pass, Input Speed remain at zero?
Ye s>>
Go To 3
No>>
Repair internal Transmission as necessary. Check all of the components relatedtotheUDandLR
clutches. Inspect the Oil Pump and repair or replace as necessary. Refer tothe Service Information for
the proper repair procedures.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Page 2772 of 5267

3.CHECK FOR INTERMITTENT OPERATION
The conditions to set this DTC are not current at this time.
Check the gearshift linkage adjustment.
Gear ratio DTCs can be set by problems in the Input and Output Speed Sensor circuits. If the vehicle passes the
Clutch Test and still sets Gear Ratio DTC, check the Speed Sensors for proper operation.
Remove the Ignition Switch Feed fuse from the TIPM.
CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being
startedingear.
WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in
personal injury or death.
Install the Transmission Simulator,Miller tool #8333 and the ElectronicTransmission Adapter kit.
Check the wiring and connectors for the Speed Sensors for a good connection, then perform a wiggle test using the
Transmission Simulator.
This DTC can also be set under extreme temperature conditions. This is usually caused by an internal problem.
Verify if the problem is only experienced under extreme hot or cold conditions.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply.
Were there any problems found?
Ye s>>
Repair as necessary.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
