Transmission additives for automatic cars are on store shelves everywhere. Are they even worth your money, or are you better off without them?
Every automatic car transmission needs a regular resupply of transmission fluid. This oily fluid is vital for your car’s safe and consistent operation, as it lubricates and pressurizes the various moving parts in the gearbox. This, in turn, allows the parts to spin, crank, pump, and so on without grinding against one another and wearing themselves down. You should always have your transmission fluid levels checked when you bring your car in for maintenance, as keeping them topped up is the first and foremost step in preventing your transmission from dying on you.

In addition to regular automatic transmission fluid, various transmission additives are available that, at least allegedly, provide additional benefits and longevity to your car when added alongside the fluid.
