JUDGEMENT OF LINE PRESSURE TESTNJAT0027S03
Judgement Suspected parts
At idleLine pressure is low in all positions.+Oil pump wear
+Control piston damage
+Pressure regulator valve or plug sticking
+Spring for pressure regulator valve damaged
+Fluid pressure leakage between oil strainer and pressure regulator valve
+Clogged strainer
Line pressure is low in particular
position.+Fluid pressure leakage between manual valve and particular clutch
+For example, line pressure is:
þ Low in ªRº and ª1º positions, but
þ Normal in ªDº and ª2º positions.
Therefore, fluid leakage exists at or around low and reverse brake circuit.
Refer to ªCLUTCH AND BAND CHARTº, AT-23.
Line pressure is high.+Maladjustment of throttle position sensor
+A/T fluid temperature sensor damaged
+Line pressure solenoid valve sticking
+Short circuit of line pressure solenoid valve circuit
+Pressure modifier valve sticking
+Pressure regulator valve or plug sticking
+Open in dropping resistor circuit
At stall
speedLine pressure is low.+Maladjustment of throttle position sensor
+Line pressure solenoid valve sticking
+Short circuit of line pressure solenoid valve circuit
+Pressure regulator valve or plug sticking
+Pressure modifier valve sticking
+Pilot valve sticking

Road TestNJAT0028DESCRIPTIONNJAT0028S01+The purpose of the test is to determine overall performance of
A/T and analyze causes of problems.
+The road test consists of the following three parts:
1. Check before engine is started
2. Check at idle
3. Cruise test
SAT496G
+Before road test, familiarize yourself with all test procedures
and items to check.
+Conduct tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
Refer to the following items.
