Transmission Fluid

All machinery needs coolant, but depending on the make, model and transmission type, the type of fluid can vary. It comes down to the setup: manual transmissions may rely on gear oil, because of physical proximity and design. But automatics typically require transmission fluid.

 

Transmission fluid needs to be changed anywhere from 50,000 miles to 100,000 miles depending on manufacturer specifications, but it’s also dependent on how you drive. The stop-and-go nature of city driving, carrying heavy loads and towing trailers creates hard driving conditions–and high driving temperatures–that strains the transmission. Without proper fluid levels and maintenance, you could experience:

  • Fluid contamination (manual)
  • Breakdown of the fluid (automatic)

 

Both scenarios can lead to a transmission breakdown. And that’s expensive to replace.
