ATF Pump Inspection

ATF Pump Inspection

1. Install the ATF pump drive gear (A), the driven gear (B), and the 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 the 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).
