Mechanic and influencer Juan José Ebenezer warns that skipping automatic gearbox maintenance can lead to costly repairs, starting at €1,500 and potentially climbing much higher. “I don't care what the manufacturer says; the automatic transmission also needs maintenance,” he says, urging drivers to trust real-world experience over the manual. Regular checks could prevent some of these problems.
Ebenezer is blunt about so-called “lifetime” automatic transmission fluid: he calls it a myth. Some carmakers say their gearboxes never need fluid changes, but he has seen what happens when people believe them. Cars often reach his workshop only after the damage is done, when repairs cost far more than routine servicing.
He focuses on two things: the transmission fluid and its filter. Both are basic to an automatic gearbox working properly. Over time, heat and friction break down the fluid, while tiny bits of metal and dirt build up. The filter is the only thing stopping those particles from moving through the system and causing more wear. Ebenezer says waiting for warning signs, such as jerks or vibrations alongside shifting trouble, is asking for trouble.
He is not the only one challenging carmaker claims. As reported earlier, other well-known mechanics have also questioned the idea of “maintenance-free” parts, especially as cars get more complex and repairs become pricier.
Several independent sources put the typical recommended interval for changing automatic transmission fluid at between 60,000 and 100,000 kilometers, especially for vehicles used in city traffic or under heavy loads. Even so-called “maintenance-free” transmissions from leading manufacturers such as ZF are often advised to have fluid changes at around 150,000 kilometers, or sooner in severe conditions.
Changing the fluid and filter costs little compared with dismantling and rebuilding a broken transmission. Even minor repairs can leave a car in the shop for days or weeks, depending on parts availability and the complexity of the job. The financial and practical impact can be immediate.
Ebenezer’s message is straightforward: timely maintenance is preferable to repair. Checking and changing transmission fluid and filters on time cuts the risk of a major breakdown. He says he has seen it again and again: most major gearbox failures could have been avoided if owners had not trusted the manufacturer’s “lifetime” promise.
Automatic gearboxes are now common on Spanish roads. Skipping maintenance might seem easy, but one mistake can turn into a repair bill of several thousand euros. Ebenezer urges drivers to trust real-world experience over marketing and to treat their gearbox with care. As cars become more complicated and repairs more expensive, he says, this is advice drivers cannot afford to ignore.
