(11) Place CLEAR suction line into a one quart
container of Mopar
t
ATF Plus 3, type 7176 automatic
transmission fluid.
(12) Turn pump ON until all transmission fluid is
removed from the one quart container and lines. This
purges any residual cleaning solvent from the trans-
mission cooler and lines. Turn pump OFF.
(13) Disconnect alligator clips from battery. Recon-
nect flusher lines to cover plate, and remove flushing
adapters from cooler lines.
ALUMINUM THREAD REPAIR
Damaged or worn threads in the aluminum tran-
saxle 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 suppli-
ers.
REMOVAL AND INSTALLATION
TRANSMISSION
CAUTION:
The transmission and torque converter
