HYDRAULIC TEST 1. PREPARATION (a) Warm up the transmission fluid. (b) Remove the transmission case test plug and mount the hydraulic pressure gauge. SST 09992-00093 Oil pressure gauge CAUTION: Perform the test at normal operating fluid temperature (50 — 80°C or 122 — 176°F). 2. MEASURE LINE PRESSURE (a) Fully apply the parking brake and chock four wheels. (b) Start the engine and check idling rpm. (c) Shift into "D" range, step down strongly on the brake pedal with your left foot and, while manipulating the accelerator pedal with the right foot, measure the line pressures at the engine speeds specified in table. (d) In the same manner, perform the test in "R" range. Engine speed Line pressure kg/cm² (psi, kPa) rpm "D" range "R" range Idling 3.7 - 4.1 5.1 - 5.7 (53 - 58) (73 - 81) (363 - 402) (500 - 559) Stall 10.6 - 13.0 14.3 - 19.0 (151 - 185) (203 - 270) (1,040 - 1,275) (1,402 - 1,863) (e) If the measured pressures are not up to specified values, recheck the throttle cable adjustment and perform a retest. EVALUATION (a) If the measured values at all ranges are higher than specified: • Throttle cable out-of-adjustment • Throttle valve defective • Regulator valve defective (b) If the measured values at all ranges are lower than specified: • Throttle cable out-of-adjustment • Throttle valve defective • Regulator valve defective • Oil pump defective • OD clutch defective (c) If pressure is low in "D" range only: • "D" range circuit fluid leakage • Front clutch defective (d) If pressure is low in "R" range only: • "R" range circuit fluid leakage • Rear clutch defective • Brake No.3 defective
