ATF PUMP INSPECTION

1. Install the ATF pump drive gear (A), driven gear (B), and ATF pump driven gear shaft (C) in the main

valve body (D). Lubricate all parts with ATF, and install the ATF pump driven gear with its grooved and
chamfered side facing up.

2. Measure the side clearance of the ATF pump drive gear (A) and driven gear (B).

ATF Pump Gears Side (Radial) Clearance

Standard (New):

ATF Pump Drive Gear:

0.210-0.265 mm (0.0083-0.00104 in.)

3. Remove the ATF pump driven gear shaft. Measure the thrust clearance between the ATF pump driven

gear (A) and the valve body (B) with a straight edge (C) and a feeler gauge (D).

ATF Pump Drive/Driven Gear Thrust (Axial)

Clearance:

Standard (New): 0.03-0.06 mm (0.001-0.002 in.)

Service Limit: 0.07 mm (0.003 in.)

SECONDARY VALVE BODY DISASSEMBLY, INSPECTION, AND REASSEMBLY

1. Clean all parts thoroughly in solvent, and dry them with compressed air. Blowout all passages.

2. Do not use a magnet to remove the check balls, it may magnetize the check balls.

3. Inspect the secondary valve body for scoring and damage.

4. Check all valves for free movement. If any fail to slide freely, refer to valve body repair (see VALVE

BODY ).

5. Coat all parts with ATF during assembly.
