Adding transmission fluid while the engine is running poses several risks⁚
- Fluid splash⁚ The moving parts within the transmission create pressure that can cause fluid to splash back out when you add more, potentially burning you.
- Air bubbles⁚ Adding fluid while the engine is running can introduce air bubbles into the system, which can interfere with the transmissions performance and cause damage;
- Overfilling⁚ Its difficult to accurately determine the correct fluid level while the engine is running. Overfilling the transmission can cause excessive pressure and damage seals and other components.
