Transmission Line Pressure Test With Vehicle Stationary
Line pressure measurement (under no load - closed throttle)

(1) Before measuring the line pressure, apply both foot and parking brakes with all wheels chocked.
(2) Maintain the temperature of ATF at approx. 70 — 80°C (158 — 176°F) during measurement. (ATF will
reach the above temperature after idling the engine for approx. 30 minutes with select lever in “N” or “P”.)

Line pressure measurement (under heavy load)

(1) Before measuring the line pressure, apply both foot and parking brakes with all wheels chocked.
(2) Measure the line pressure when select lever is in “R”, “2” with engine under stall conditions.
(3) Measure the line pressure within 5 seconds after shifting the select lever to each position. (If line pressure
needs to be measured again, allow the engine to idle, and then stop it to cool down for at least one minute.)
(4) Maintain the temperature of ATF at approx. 70 — 80°C (158 — 176°F) during measurement (ATF will
reach the above temperature after idling the engine for approx. 30 minutes with the select lever in “N” or “P”.)
3) Temporarily attach the gauge to a suitable place in the driver's compartment, make or remove a blind plug
located in front of the toe board and pass the hose of the gauge to engine compartment.
4) Remove the test plug and install the gauge fitting instead.
5) Connect the gauge to the hose.
6) Check note values in accordance with throttle position.

Normal line pressure run between, 44 - 189 psi.
Drive Throttle fully closed 44 — 60 psi
Reverse Throttle fully opened 220 — 249 psi
(2) Throttle fully opened. 164 — 189 psi
