How to Put Transmission Fluid in an Oldsmobile Alero

by Matt Scheer

The Oldsmobile Alero was manufactured in Lansing, Michigan between 1999 and 2004. It was the company's last compact car produced. One complaint repeated about the car is that it's difficult to fill with transmission fluid. However, filling the car's transmission fluid is a relatively simple task once you find the fill cap. Finding that part is the most difficult part of the process.

Step 1

Drive the car for about 10 minutes to warm up the engine and fluids.

Step 2

Open the hood and prop it up with the safety bar. Locate the transmission fluid dipstick. The dipstick is located near the rear of the engine and is labeled "ATF Engine Oil." Twist off the cap and wipe the dipstick with a clean paper towel. Check to see what color the fluid is. The fluid should be a clear red color. If it's brown the transmission fluid should be replaced. With normal use, the transmission fluid needs to be changed every 30,000 miles.

Step 3

Place the dipstick back in the engine and bring it out again. Look at how high the liquid comes up on the stick. It should be between the MIN and MAX line. If it's below the middle, its time to put more fluid in the tank. If its below the MIN line it means the tank has a leak and needs to be repaired before putting more fluid inside.

Step 4

Check the owner's manual for amount and type of transmission fluid used in the vehicle. These vary for the different years of the car. Locate the transmission fluid fill port, which is next to the dipstick. Remove the black cap.

Step 5

Place a funnel in the fill port hole and pour in an appropriate amount of transmission fluid. Check the levels according to directions in Step 3. Put in more if needed and re-check. Replace cap securely.
