At stall test
1 Start engine and place select lever in "D"
range
2 Apply foot brake and accelerate to wide-open
throttle
3 Quickly note the line pressure and immediately
release throttle
4 Shift select lever to "N".
5 Cool off A.T F.
6 Perform line pressure testing in the same man-
ner as in steps 2 through 6 with select lever
in
"2". "1" and "R", respectively.
Do not perform tests for more than five
seconds
at any shift range.
Do not proceed to next "range" test imrnedi-
ately after one "range"
test is done. Wait until
oil temperature decreases
