Please proceed with lesson.

If the main transmission oil temperature is in the precautionary range (105 - 120˚C) the corrective action is:

REDUCE POWER.

If transmission temperature is noted between 105 - 120˚C the corrective action is to:

Reduce power.Check airspeed.Land as soon as possible.Land immediately.

If the main transmission oil pressure is in the upper precautionary range (65 - 130 PSI) or above the corrective action is:

MONITOR OTHER TRANSMISSION GAUGES.

While in flight if transmission pressure is noted above 65 PSI the corrective action is:

Monitor other transmission gauges.Reduce power.Land as soon as possible.Land as soon as practicable.
