The Most Trusted Mobile Gearbox Oil Change

Gearbox oil lubricates gears and bearings that carry the full torque of the engine, and it does so under pressures that ordinary engine oil would not survive. It also carries friction modifiers that let synchronisers work smoothly. Over time those additives deplete and the oil fills with fine metal particles. Michanic changes gearbox oil at your home or office, using the specific fluid your transmission requires rather than a general purpose gear oil.

Why Choose Our Mobile Gearbox Oil Change Services?

  1. Exact Fluid Specification:
    Manual and automatic transmissions are extremely particular about fluid. The wrong specification causes poor shifting and, in automatics, rapid internal wear.
  2. Filled to Level, Not by Volume:
    Many gearboxes are filled to a level plug at a specified temperature rather than by measured quantity. Getting this wrong causes overheating or starvation.
  3. Drain Plug Inspected:
    Magnetic drain plugs catch metal. What is on that plug tells you a great deal about the condition inside.
  4. At Your Home or Office:
    No need to book the car in, and no lift required for the work we carry out.

Why We are the Best Choice for Mobile Gearbox Oil Change

  • Right Fluid, Confirmed:
    The specification is checked against your exact model and transmission code rather than assumed from the model name.
  • Washers Renewed:
    Drain and fill plug washers are replaced, because a reused crush washer weeps and gearbox oil is difficult to clean off a driveway.
  • Condition Reported:
    If the old oil is heavily contaminated or smells burnt, you are told what that suggests rather than just receiving fresh oil.
  • Shift Quality Checked:
    The vehicle is driven or run through the gears afterwards to confirm the change has done what it should.

A gearbox is a sealed environment where the only thing separating hardened steel surfaces is a film of oil. As the additives deplete, that film thins under load, and the fine metal particles the gearbox has shed become an abrasive paste circulating through the bearings and synchronisers. In an automatic the consequences arrive sooner, because the same fluid operates the clutches and valve body hydraulically, so degraded fluid causes harsh or slipping shifts before it causes wear. Transmission repairs are among the most expensive on any car, and fluid is the cheapest protection against them.

Frequently Asked Questions

  • How often should gearbox oil be changed?
    Check your service book. Manual gearboxes commonly call for it somewhere between sixty and one hundred thousand kilometres, and many automatics benefit from a change well before the point at which problems appear, even when described as lifetime filled.
  • Is lifetime fill really lifetime?
    It means the life the manufacturer designed for, which is not the same as the life you want from the car. Fluid still degrades, and many transmissions described as sealed for life benefit measurably from a change at high mileage.
  • What are the signs that gearbox oil needs changing?
    Notchy or stiff gear changes, difficulty engaging a particular gear, whining that changes with road speed, and in automatics harsh shifts or hunting between gears. Dark, gritty or burnt smelling fluid confirms it.
  • Can I use any gear oil?
    No. Transmissions specify viscosity and an additive package, and automatics are particularly sensitive because the fluid also operates the clutches hydraulically. The wrong fluid causes poor shifting immediately and wear over time.
  • Will changing old gearbox oil cause problems?
    On a very high mileage automatic that has never been serviced, a change occasionally reveals wear that the old degraded fluid was masking. That is the wear showing rather than the service causing it, and a condition assessment comes first.
