*1: Operates when overdrive control or A/T mode switch is being set in ªOFFº or ªSPORTº position.
*2: Oil pressure is applied to both 2nd ªapplyº side and 3rd ªreleaseº side of band servo piston. However, brake band does not contract because oil pressure area on the ªreleaseº side is greater than that on the ªapplyº side.
*3: Oil pressure is applied to 4th ªapplyº side in condition *2 above, and brake band contracts.
*4: A/T will not shift to 4th when overdrive control or A/T mode switch is set in ªOFFº or ªSPORTº position.
q : Operates.
: Operates when throttle opening is less than 3/16, activating engine brake.
v : Operates during ªprogressiveº acceleration.
: Operates but does not affect power transmission.
: Operates when throttle opening is less than 3/16, but does not affect engine brake.

Line Pressure Test
LINE PRESSURE TEST PORTS
ILocation of line pressure test ports.
I Always replace line pressure plugs as they are self-
sealing bolts.
LINE PRESSURE TEST PROCEDURE
1. Check A/T and engine fluid levels. If necessary, add fluid.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature.ATF operating temperature: 50 - 80ÉC (122 - 176ÉF)
3. Install pressure gauge to corresponding line pressure port.

4. Set parking brake and block wheels.
IContinue to depress brake pedal fully while line pressure
test is being performed at stall speed.
5. Start engine and measure line pressure at idle and stall speed.
I When measuring line pressure at stall speed, follow the
stall test procedure.
Line pressure: Refer to SDS, AT-201.
JUDGEMENT OF LINE PRESSURE TEST
Judgement Suspected parts
At idle Line pressure is low in all
positions.
I
Oil pump wear
I Control piston damage
I Pressure regulator valve or plug sticking
I Spring for pressure regulator valve damaged
I A/T fluid pressure leakage between oil strainer and pressure regulator valve
I Clogged strainer
Line pressure is low in par-
ticular position. I
Fluid pressure leakage between manual valve and particular clutch
I For example, line pressure is:
Ð Low in ªRº and ª1º positions,
Ð Normal in ªDº and ª2º positions.
Then, fluid leakage exists at or around low and reverse brake circuit.
Refer to ªCLUTCH AND BAND CHARTº, AT-11.
Line pressure is high. IMal-adjustment of throttle position sensor
I A/T fluid temperature sensor damaged
I Line pressure solenoid valve sticking
I Short circuit of line pressure solenoid valve circuit
I Pressure modifier valve sticking
I Pressure regulator valve or plug sticking
I Open in dropping resistor circuit
At stall speed Line pressure is low.
IMal-adjustment of throttle position sensor
I Line pressure solenoid valve sticking
I Short circuit of line pressure solenoid valve circuit
I Pressure regulator valve or plug sticking
I Pressure modifier valve sticking
I Pilot valve sticking
