(f) In the same manner, perform the test in R range. kg/cm² (psi, kPa) Engine | D range | R range | Idling | Stall | Idling | Stall 7M-GE | 3.5 — 4.3 (50 — 61, 343 — 422) | 8.8 — 11.5 (125 — 164, 863 — 1,128) | 4.9 — 6.1 (70 — 87, 481 — 598) | 12.2 — 15.9 (174 — 226, 1,196 — 1,559) 7M-GTE | 4.1 — 4.9 (58 — 70, 402 — 481) | 12.3 — 15.0 (175 — 213, 1,206 — 1,471) | 5.0 — 6.2 (71 — 88, 490 — 608) | 15.1 — 18.8 (215 — 267, 1,481 — 1,844) 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 • Primary regulator valve defective • Oil pump defective • O/D direct clutch defective (c) If pressure is low in the D range only: • D range circuit fluid leakage • Forward clutch defective (d) If pressure is low in the R range only: • R range circuit fluid leakage • Direct clutch defective • First and reverse brake defective HYDRAULIC TEST [THIS IS FIGURE: Illustration showing hydraulic test setup with a mechanic working under a vehicle, accompanied by circular detail images showing gauge readings marked with D and R, a pressure gauge, and what appears to be RPM gauges] A71961
