Direct Clutch Pressure Test

  1. Attach accurate 0-300 psi (0-21.1 kg/cm2 ) pressure gauges to the forward and direct clutch pressure taps on right side of transmission. See Figure . Gauge hose must be long enough to read gauge while road testing vehicle.
  2. Drive vehicle. When pressure is applied to direct clutch, note difference between line pressure on forward clutch gauge and direct clutch gauge. If difference is less than 15 psi (1.1 kg/cm2 ), direct clutch circuit is good.
  3. If difference is greater than 15 psi (1.1 kg/cm2 ), there could be a leak in direct clutch pressure circuit.
