TM 8-2320-280-20-1
REFERENCE INFORMATION
TRANSMISSION SYSTEM
(4L80-E)
If the drivetrain system checks out OK, the
problem is either the transmission itself, the
shifter or the modulator. The DRIVETRAIN
tests are located in Paragraph 2-33of this
manual.
Make sure that the detents in the shifter
correspond to the shift positions shown on
the plate. Have an assistant move the shifter
and look to see that the linkage is moving at
the transmission.
Linkage repair and adjustment procedures
are shown in Paragraph 5-13.
Look for a fan cut-off switch problem if the
vehicle was not shifting, or was not shifting
as well as it should be.
NOTE
Run the BRAKES and DRIVETRAIN tests in
this manual. If you don’t find any faults, notify
DS maintenance.
