(3) Connect the SSTs (49 L019 014, 49 B019
901B, and 49 0378 400C) to the low clutch
pressure inspection port (D and M range line
pressures) or reverse clutch pressure
inspection port (R position line pressure).
(4) Start the engine and warm it up until the ATF
reaches 60—70 °C {140—158 °F}.
(5) Shift the selector lever to D range.
(6) Read the line pressure at idle for the
remaining ranges in the same manner.
• M range (1GR, 2GR)
• R range
ATF temperature
60—70 °C {140—158 °F}
Turn off all electrical loads
(7) Turn the engine off.
2. Engine stall speed.
Caution
• Perform the line pressure test at engine idling prior to performing the test at engine stall. If line
pressure is low at idle, do not perform the test at engine stall or further transaxle damage will
occur.
(1) Replace the SST (49 B019 901B) with the gauge of the SST (49 0378 400C).
(2) Start the engine.
Caution
• Do not maintain WOT in any gear range for more than 5 seconds or transaxle damage will occur.
(3) Firmly depress the brake pedal with the left foot, and then gradually depress the accelerator pedal to the
floor (WOT) with the right.
(4) When the engine speed no longer increases, quickly read the line pressure and release the accelerator
pedal.
(5) Shift the selector lever to N position and let the engine idle for 1 minute or more to cool the ATF.
(6) Read the line pressure at the engine stall speed for the remaining ranges in the same manner.
• M range (1GR, 2GR)
• R range
ATF temperature
60—70 °C {140—158 °F}
Turn off all electrical loads
(7) Shift the selector lever to P position.
(8) Turn off the engine.
(9) Remove the SSTs and install a new square head plug and O-ring in the line pressure inspection port.
