What is the maximum transmission oil temperature takeoff?

• A. 0-115 °C
• B. 115 °C max
• C. 120-130 °C
• D. 100 °C max

Answer: (B)

The value to remember is 115 °C as the maximum allowed transmission oil temperature for takeoff. During takeoff, the transmission is under peak load and generates a lot of heat, so the oil must stay within a temperature range where it remains viscous enough to lubricate moving parts properly. If the oil gets hotter than 115 °C, lubrication can degrade, increasing wear or damaging gears and bearings. So you’re within limits if the oil temperature is at or below 115 °C; you should not perform takeoff if it’s above this limit and instead let the system cool or take other cooling actions before attempting takeoff.
