Test Result Indications

1. If proper line pressure, minimum to maximum, is found in any one test, the pump and pressure regulator are working properly.
2. Low pressure in D, 1, and 2 but correct pressure in R indicates rear clutch circuit leakage.
3. Low pressure in D and R but correct pressure in 1 indicates front clutch circuit leakage.
4. Low pressure in R and 1 but correct pressure in 2 indicates rear servo circuit leakage.
5. Low line pressure in all positions indicates a defective pump, a clogged filter, or a stuck pressure regulator valve.
