“M2” Position

The front brake fastens the front sun gear.

The forward brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.

The direct clutch is coupled, and the rear carrier and rear sun gear are connected.

The low coast brake fastens the mid sun gear.

During deceleration, the low coast brake regulates forward rotation of the mid sun gear and the engine
brake functions.

TROUBLE DIAGNOSIS
Revision: 2004 November 2004 FX35/FX45
CAUTION:
Run the engine at idle for at least one minute.
Judgement Stall Test
O: Stall speed within standard value position
H: Stall speed higher than standard value
L: Stall speed lower than standard value
Stall test standard value position
LINE PRESSURE TEST
Line Pressure Test Port
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the A/T fluid reaches in range of 50 to 80°C (122
to 176°F), then inspect the amount of A/T fluid and replenish if necessary.
NOTE:
The A/T fluid temperature rises in range of 50 to 80°C (122 to 176°F) during 10 minutes of driving.
3. Remove front propeller shaft from vehicle (with AWD models). Refer to PR-4, "
Removal and Installation" . Stall speed:
VQ35DE engine: 2,650 - 2,950 rpm
VK45DE engine: 2,300 - 2,600 rpm
