What should the inspector do if they notice a steady leak of fluid from the transmission during a warm-up?

• A. Abort the inspection as the vehicle is not safe to run on the dyno.
• B. Continue the inspection with caution.
• C. Record the leak and proceed with the dyno test.
• D. Repair the leak and then proceed.

Answer: (A)

Safety and readiness for the dyno test hinge on having a vehicle that is leak-free and mechanically sound. A steady transmission fluid leak during warm-up signals a real hazard: under load the drivetrain can spray fluid, the fluid can ignite if it contacts hot exhaust, surfaces can become slippery, and the dyno equipment itself can be damaged. Because of these risks, the inspector must stop the inspection immediately, remove the vehicle from the dyno, and address the leak before any further testing. Recording the leak or continuing with the test would not remove the danger, and repairing the leak is the correct next step but only after halting and fixing the issue first.
