Severe use places significantly more stress on the transmission fluid, breaking down its additive package faster. Some manufacturers now specify "lifetime" fluid, which implies the fluid does not need changing as long as the transmission is functioning.
Manual Transmission Oil Change Frequency Needed: Key Factors and Recommendations
Conversely, manual transmissions are generally simpler and rely on gear oil that is primarily a lubricant. A more thorough maintenance practice is a transmission flush, which uses a machine to exchange the old fluid for new dynamically.
The traditional "drain and replace" method only removes about 40% of the old fluid because the torque converter and cooler lines hold a significant volume of fluid. Visible changes are also telling; fresh ATF is typically a bright red or pink color, while old fluid turns brown or dark red.
