Ferrari F1 Gearbox Oil Change & Filter Screen Service
Professional Technical Procedure & Reference Guide
This guide provides a professional, technically accurate procedure for servicing Ferrari F1 automated manual gearboxes.
It covers gearbox oil draining, filter screen removal, cleaning, inspection, and refilling.
⚠️ Improper handling of the plastic filter screen can result in breakage and gearbox contamination.
Tools Required
- 22mm socket – Gearbox side fill plug
- 14mm hex (Allen) – Gearbox drain plug (verify on vehicle)
- 13mm socket – Exhaust hanger bracket nuts
- 8mm socket – Filter screen retaining bolt
- Hand-operated fluid pump – Required for refill
Step 1: Gearbox Drain Plug Location
The gearbox drain plug is located at the center mass of the gearbox housing.
Position a drain pan directly beneath and allow the fluid to fully drain.
Step 2: Gearbox Oil Filter Screen Location
Standing behind the vehicle, the filter screen is located on the right-hand (U.S. passenger) side of the gearbox,
adjacent to the exhaust hanger bracket.
Step 3: Exhaust Hanger Removal
Remove the two 13mm nuts securing the exhaust hanger to the gearbox and rotate the hanger out of the way.
Full exhaust removal is not required.
Step 4: Filter Screen Removal & Cleaning
⚠️ WARNING: The filter screen is plastic. Do NOT pry straight outward.
Use a flathead screwdriver or small pry bar to rotate the screen gently in a circular motion to free it before removal.
Clean the filter screen using brake cleaner or carburetor cleaner.
Inspect for debris, cracks, or deformation.
Step 5: O-Ring Inspection
Lightly coat the O-ring with gearbox oil prior to reinstallation.
If the O-ring is flattened, brittle, or damaged, replace it.
Step 6: Gearbox Fill Plug Location
The fill plug is located directly behind the filter screen area.
Later models include a rubber damper with an access cutout for the fill plug.
Step 7: Gearbox Refill Procedure
Due to clearance limitations, a hand-operated fluid pump is required.
Fill the gearbox until fluid reaches the bottom edge of the fill hole.
Approximate capacity is 3 quarts; however, always fill to the level of the fill plug opening rather than by volume.
Professional Tip: This hand pump is also useful for F1 hydraulic reservoir service and fluid extraction.
