What is the purpose of transmission fluid?

Transmission fluid is a slippery liquid that acts as a lubricant for all of the moving parts inside your transmission. In an automatic transmission, this fluid also serves as a coolant and a viscous fluid that transmits power from the engine to the transmission. A variety of fluids are used for different transmissions.

Just so, is Mercon V compatible with ATF 4?

Valvoline's ads claim this fluid is “recommended” for Chrysler products. But, again, a fluid compatible with Dexron III or Mercon is not going to be compatible with Chrysler ATF+4 or ATF+5, nor will it be proper for either Dexron VI or Ford LV vehicles.

Is oil and transmission fluid the same?

Transmission fluid is used by your steering system to keep its parts moving smoothly. A couple of differences are the following: An engine oil is designed to deal with the products of combustion, whereas an automatic transmission fluid (ATF) does not see contaminants from fuel burning.

Do you check the transmission fluid with the car on or off?

To check your automatic transmission fluid, follow these steps: Pull out the dipstick. With the gearshift in Neutral or Park and the parking brake on, let your engine run. Be sure the engine is warm when you pull out the dipstick.
