Ferrari PTU Fluids and Hoses: Identify the Correct Service
Identify the system before selecting fluid
The PTU and rear transmission are separate service contexts. Do not choose a fluid solely because it is marketed for Ferrari or appears beside another drivetrain product. Confirm the required specification and procedure for the exact assembly.
Read the supplied contents
The linked PTU oil-set listing describes a packaged offering. Package quantities are not a universal fill instruction. The installing workshop must use the applicable workshop information for fluid specification, quantity and service procedure.
Check the hose reference
For a hose inquiry, record the markings and inspect the installed arrangement. Reference 278335 should be checked against the relevant application and current listing. A hose leak should be diagnosed before assuming that replacing a set resolves all PTU faults.
Plan service and keep records
Provide photographs and existing diagnostic findings when contacting GTE Engineering. Retain the service details and fluid specifications used. This article introduces the product categories; it does not replace vehicle-specific maintenance instructions.
