A/T FLUID COOLER INSPECTION PROCEDURE
1.
Inspect the coffee filter for debris.
a.
If small metal debris less than 1 mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the A/T fluid cooler/radiator can be re-used and
the procedure is ended.
b.
If one or more pieces of debris are found that are over 1 mm
(0.040 in) size and/or peeled clutch facing material is found in
the coffee filter, the A/T fluid cooler is not serviceable. The A/T
fluid cooler/radiator must be replaced and the inspection proce-
dure is ended. Refer to
A/T FLUID COOLER FINAL INSPECTION
After performing all procedures, ensure that all remaining oil is cleaned from all components.

A/T CONTROL SYSTEM
Shift Mechanism
NCS000BD
The A/T uses compact triple planetary gear systems to improve power-transmission efficiency, simplify con-
struction and reduce weight.
It also employs an optimum shift control and super wide gear ratios. They improve starting performance and
acceleration during medium and high-speed operation.
