Performance Test
• NECESSARY TEST GAUGES
1) Tachometer (It is desirable to be able to read to 50 rpm.)
2) Vacuum gauge (It is used for measuring intake manifold
vacuum.)
3) OIL PRESSURE GAUGE (398573600).
4) OIL PRESSURE ADAPTER (498897100).
5) Stop watch.
1. STALL TEST
The stall test is of extreme importance in diagnosing the con-
dition of the automatic transmission and the engine. It should
be conducted to measure the engine stall speeds in all shift
ranges except the P and N ranges.
159
Purposes of the stall test
1) To check the operation of the automatic transmission
clutch and brake band.
2)
To check the operation of the torque converter.
3) To check engine performance.
Test Methods
• Preparations before test
CD
Check that throttle valve opens fully.
®
Check that engine oil level is correct.
@
Check that coolant level is correct.
@
Check that A TF level is correct.
@
Check that differential gear oil level is correct.
®
Increase ATF temperature to 60 - 80°C (140 - 176°F) by
idling the engine for approximately 30 minutes (with
select lever set to "N" or "P").
