ATF Pump Inspection

ATF Pump Inspection

1. Lubricate the ATF pump drive gear (A), the ATF pump driven gear (B), and the ATF pump driven gear shaft (C) with ATF, then install them in the main valve body (D). 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 the ATF pump driven gear (B).










3. Remove the ATF pump driven gear shaft. Measure the thrust clearance between the ATF pump drive gear (A) and the main valve body (B), and between the ATF pump driven gear (C) and the main valve body, using a straight edge (D) and a feeler gauge (E).










4. If the measurements are out of the standards, replace the main valve body assembly.
