Additionally, extreme climates play a role. Severe use places significantly more stress on the transmission fluid, breaking down its additive package faster.
Why Only 40 Percent of Old Transmission Fluid Gets Drained Out
Automatic Transmissions The type of transmission you have also dictates the maintenance schedule. Visible changes are also telling; fresh ATF is typically a bright red or pink color, while old fluid turns brown or dark red.
However, these numbers are not arbitrary; they are the result of extensive testing. In very hot environments, the fluid degrades due to thermal stress, while cold climates that require frequent short trips prevent the fluid from reaching optimal operating temperature, leading to moisture contamination and sludge buildup.
Why Only 40% of Old Fluid Gets Replaced During a Drain
Automotive engineers design specific fluid change intervals tailored to each model’s transmission design and expected use cases. A more thorough maintenance practice is a transmission flush, which uses a machine to exchange the old fluid for new dynamically.
