What is the takeoff/max transmission oil pressure?

• A. 60 psi
• B. 65 psi
• C. 75 psi
• D. 70 psi

Answer: (A)

Oil pressure for the transmission is a measure of how well the gears are being lubricated and cooled, especially when loads are highest during takeoff. The takeoff or maximum spec is the highest pressure the system should be allowed to reach without risking damage. That limit is set by the transmission design and its relief path to prevent over-pressurizing seals, hoses, and bearings. So the value of 60 psi is the upper bound the system is designed to tolerate during peak takeoff conditions. Pressures higher than this would exceed the component limits and could lead to leaks or failure, which is why 60 psi is the correct choice.
