🔧 Transmission Fluid - Drain and Fill

This service drains the old automatic transmission fluid and refills it to the correct level. On your Beetle, the fill level is temperature-sensitive, so the car must be level and the fluid must be set at the proper temperature for an accurate fill.

Difficulty Level: Intermediate | Estimated Time: 1.5-2.5 hours
