Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 1942
AIR CHECKING TRANSMISSION CLUTCH OPERATION
Air-pressure testing can be used to check transmis-
sion clutch operation. The test can be conducted with
the transmission either in the vehicle or on the work
bench, as a final check.
Air-pressure testing requires that the oil pan and valve
body be removed from the transmission. The clutch
apply passages are shown in the NAG1 Clutch Appli-
cation Ports graphic.
NOTE: The air supply which is used must be free
of moisture and dirt. Use a pressure of 30 psi to
test clutch operation.
Apply air pressure at each port. If the clutch is func-
tioning, a soft thump will be heard as the clutch is
applied. The clutch application can also be felt by
touching the appropriate element while applying air
pressure. As the air pressure is released, the clutch
should also release.
STANDARD PROCEDURE - ALUMINUM THREAD REPAIR
Damaged or worn threads in the aluminum transmission case and valve body can be repaired by the use of Heli-
Coils™, or equivalent. This repair consists of drilling out the worn-out damaged threads. Then tap the hole with a
special Heli-Coil™ tap, or equivalent, and installing a Heli-Coil™ insert, or equivalent, into the hole. This brings the
hole back to its original thread size.
Heli-Coil™, or equivalent, tools and inserts are readily available from most automotive parts suppliers.
REMOVAL
NOTE: If the transmission is being reconditioned (clutch/seal replacement) or replaced, it is necessary to
perform the TCM Adaptation Procedure using the scan tool (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/TRANSMISSION CONTROL MODULE - STANDARD PROCEDURE).
