CHAPTER 2
TROUBLESHOOTING PROCEDURES
OVERVIEW
Troubleshooting is a logical, systematic search for the cause(s) of malfunction(s). Direct
Support troubleshooting of the transmission can only be performed with the transmission
installed in the vehicle.
NOTE
When troubleshooting is performed with the transmission in a vehicle, the
information in this manual will be used in conjunction with the information
contained in the applicable - 20 level vehicle manual.
The purpose of troubleshooting is to establish the nature and extent of repair required to return
the transmission to serviceable condition. Thorough troubleshooting before the transmission is
removed from the vehicle may reveal malfunctions external to the transmission. Correction of
such external malfunctions may prevent the unnecessary effort of removing the transmission.
Troubleshooting by a Direct Support shop is necessary to verify the diagnosis made before the
transmission was removed. Such troubleshooting may be the only means of uncovering all
defects in a transmission received in an unserviceable condition from another activity.
Troubleshooting may be necessary to determine the cause when a repaired transmission fails to
perform properly.
