Don’t be afraid of oil changes! MEYLE advises on changing the oil in automatic gearboxes.

Don’t be afraid of oil changes!  MEYLE advises on changing the oil in automatic gearboxes.

‘Automatic transmissions? They don’t need an oil change!’ Though debunked long ago, this rumour has proven quite persistent. Transmission oil undergoes a natural ageing process, with the oil wearing out and additives diminishing over time. So it’s all the more important to change the oil: this prevents damage to the transmission and maintains transmission function and driving comfort. Yet people still shy away. They shouldn’t! Based in Hamburg, spare parts manufacturer MEYLE offers over 60 oil change kits, which come with all the components required for an oil change: filters, seals, screws, drain/intake plugs, magnets and the amount of transmission oil the application calls for. This reduces stress and saves money – for workshops and drivers alike. Now, MEYLE’s advice makes changing the oil even easier.

  1. Before you change the oil, read the manufacturer’s instructions about how to do it and the transmission oil specifications, and be sure to follow them.

That’s because disallowed gearbox oil can cause implausible changing operations and major gearbox damage.

  1. Scan and back up fault memory before changing the gearbox oil.

Scan the fault memory using the diagnostic interface and, ideally, print out saved faults. This will help you identify any existing damage and avoid unnecessary servicing.

  1. Lift the vehicle as horizontally as possible on the lift.

That way you can measure the oil level accurately.

  1. Check the external mechatronic plug-in connector for leaks.

If necessary, replace the plug casing and seal, tighten it with the prescribed torque, or check that the plug catch is positioned correctly         .
Practical: the seals and plug casings you need are included in the MEYLE kit.

  1. You should always replace the sump screw.

That’s because once-off stress bolts are often used.

Intelligent: new oil sump screws are included in the MEYLE kit.

  1. Empty the torque converter

Always drain any remaining oil from the torque converter if you can. To do so, turn the torque converter to the right position. With some gearboxes you have to remove the additional oil pump to get to the torque converter’s outlet screw.

  1. Fill the torque converter

Run the engine at raised revs of between around 1500 and 2000 rpm, under no load, in neutral, for 20 seconds to fill the torque converter. The same applies to a gearbox that does not have an outlet screw on its torque converter.

  1. The right transmission oil temperature

You can only measure the correct oil level once the transmission oil has reached the prescribed temperature. Again, comply with what the manufacturer says.

  1. Reset adaption values

With some vehicles, the manufacturer stipulates transmission adaption after changing the oil, which is done on a suitable test bed or while driving, using the menus on the diagnostic device
Which oil for which gearbox? And at what intervals? As a practical overview, MEYLE offers a compact poster to download at www.meyle.com/oilchangekits. It’s worth looking.
