Normal transmission temp. is between 160-220 degrees.

• A. 100-140
• B. 120-180
• C. 150-210
• D. 160-220

Answer: (D)

Transmission temperature has a normal operating window that reflects when the fluid is performing best. For automatic transmissions, a typical safe range is about 160 to 220 degrees Fahrenheit. Staying in this window means the fluid isn’t too thick yet isn’t overheated, so lubrication and cooling of gears, clutches, and seals stay effective under normal driving and heavy-duty tasks like pumping or climbing. If the temperature falls below 160, the fluid can be too thick, reducing flow and increasing wear; if it climbs above 220, the fluid can degrade or lose its lubricating power, risking damage. The option that exactly matches 160–220 degrees corresponds to this widely accepted normal range, making it the best choice.
