Test Result Indications

WARNING: This page is about a different variant/trim than selected.
  1. If proper line pressure is found in any one test, the pump and pressure regulator are working properly.
  2. Low pressure in all positions indicates a defective pump, a clogged filter, or a stuck pressure regulator valve.
  3. Clutch circuit leaks are indicated if pressures do not fall within the specified pressure range.
  4. If the overdrive clutch pressure is greater than 5 psi in  6 of Test Three, a worn reaction shaft seal ring or a defective solenoid assembly is indicated.
  5. If the underdrive clutch pressure is greater than 5 psi in  4 of Test Two-A, a defective solenoid/pressure switch assembly or controller is the cause.
ALL PRESSURE SPECIFICATIONS ARE PSI (on hoist, with wheels free to turn)
