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

TROUBLE-SHOOTING AND DIAGNOSES
Stall
The stall test is an effective method of testing
clutch and band holding ability, torque converter
one-way clutch operation, and engine performance
A
stall test should only be performed as a last
resort because of the high fluid temperature it
generates and the excessive load it places on the
engine and transmission.
CAUTION:
a. Transmission and engine fluid levels should
b
c.
d
always be checked and fluid added as needed.
Run engine to
attain proper warm-up.
During test, never
hold throttle wide-open for
more than
5 seconds
Do not test more than two gear ranges without
driving vehicle to
cool off engine and trans-
mission
STALL TEST PROCEDURE
1 Set parking brake and block wheels
SAT597
2 Install a tachometer where it can be seen by
driver during
test
3 Start engine and place select lever in "D"
range
4 Apply foot brake and accelerate to wide-open
throttle
5 Quickly note the engine stall speed and imme-
diately release throttle
