One technician should observe the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.\n• Be careful to prevent the oil pressure gauge hose from interfering with the exhaust pipe.\n(a) Warm up the transmission fluid.\n(b) Remove the test plug on the transmission case left side and connect the oil pressure gauge (SST). SST 09992–00094 (Oil pressure gauge)\nHINT: Connecting the oil pressure gauge will be made easier by moving LH side heat insulator aside.\n\nSST 09992-00094\n09992-00150\nGauge Assy\nStraight Adaptor\nSST\nAT5164 AT5439\nZ13766\n\n(c) Fully apply the parking brake and chock the 4 wheels.\n(d) Start the engine and check idling RPM.\n(e) Keep your left foot pressed firmly on the brake pedal and shift into D position.\n(f) Measure the line pressure when the engine is idling.\n(g) Press the accelerator pedal all the way down. Quickly read the highest line pressure when engine speed reaches stall speed.\n(h) In the same manner, do the test in R
