Step-by-Step Procedure

Complete fluid change process from preparation to verification.

Vehicle setup: Park on level surface, engage parking brake, chock rear wheels.
Access transmission: Lift vehicle safely using jack and secure with jack stands.
Locate plugs: Identify drain plug (bottom) and fill plug (side) of transmission.
Drain fluid: Place drain pan under transmission, remove drain plug, allow complete drainage.
Inspect plugs: Check drain plug magnet for metal particles, clean if necessary.
Reinstall drain plug: Torque to specification (typically 30-40 ft-lbs).
Fill transmission: Insert funnel into fill hole, add fluid until it reaches fill hole bottom.
Verify level: Reinstall fill plug, torque to specification, lower vehicle.
Test operation: Start engine, operate clutch, shift through all gears.
Final check: Verify no leaks, proper shifting operation.

CAUTION! Use only specified transmission fluid. Overfilling or underfilling can cause transmission damage.

Post-Service Verification

Essential checks after fluid change completion.

Fluid level verification: Check for proper fill level at fill plug opening
Leak inspection: Monitor for any fluid seepage around plugs and seals
Shift quality: Test all gears for smooth engagement and operation
Noise assessment: Listen for unusual sounds during operation
Clutch operation: Verify proper clutch pedal feel and engagement
Road test: Perform test drive to confirm normal shifting under load

Tip: Recheck fluid level after initial drive as fluid may settle
