AT2–48 A340E (2JZ—GTE) AUTOMATIC TRANSMISSION – TROUBLESHOOTING HYDRAULIC TEST MEASURE LINE PRESSURE NOTICE: • Do the test at normal operating fluid temp. 50–80°C (122–176°F) • The line pressure test should always be carried out in pairs. One technician should observe the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test. • Be careful to prevent the oil pressure gauge hose from interfering with the exhaust pipe. (a) Warm up the transmission fluid. (b) Remove the test plug on the transmission case left side and connect the oil pressure gauge (SST). SST 09992–00094 (Oil pressure gauge) HINT: Connecting the oil pressure gauge will be made easier by moving LH side heat insulator side. SST RPM RPM AT5309 208983 (c) Chock the 4 wheels. (d) Fully apply the parking brake. (e) Start the engine and check idling speed. (f) Keep your left foot pressed firmly on the brake pedal and shift into D position. (g) Measure the line pressure when the engine is idling. (h) Fully depress the accelerator. Quickly read the highest line pressure when engine speed reaches stall speed. NOTICE: Release the accelerator pedal and stop test if the wheels begin to rotate before the engine speed reaches specified stall speed. (i) In the same manner, do the test in R position.
