How to check and refill transmission fluid on a 1969 AMC AMX?

It's crucial to maintain the transmission fluid in your 1969 AMC AMX to ensure the longevity and smooth operation of the vehicle. Low or degraded transmission fluid can lead to shifting problems, slipping, or even complete transmission failure. If you notice difficulty shifting gears or strange noises from the transmission, it may be time to check and refill the fluid. Here is how to solve this issue.

Step 1: Prepare the Vehicle

Before you begin, ensure your AMC AMX is parked on a level surface and that the engine is off. Engaging the parking brake adds an extra layer of safety. Ideally, the fluid should be checked when the transmission is warm, so you may want to run the car for a few minutes and then turn it off.

Step 2: Locate the Transmission Dipstick

Open the hood of your car. The transmission dipstick is usually located toward the back of the engine, near the firewall. In the 1969 AMC AMX, it is a long, thin metal rod with a loop or T-handle at the top, often colored to differentiate it from the oil dipstick.

Step 3: Check the Fluid Level

Pull the dipstick out and wipe it clean with a rag or paper towel. Insert it back fully into the tube, then pull it out again to check the fluid level. The dipstick will have markings indicating the "Full" and "Add" levels.

Step 4: Inspect the Fluid Condition

Inspect the fluid on the dipstick: it should be a reddish color. If it appears dark brown or has a burnt smell, it’s time to change the fluid completely, not just refill it.

Step 5: Add Transmission Fluid

If the fluid level is low, you'll need to add more. Locate the transmission fluid fill tube; it’s the same tube from which you pulled out the dipstick. Using a funnel, carefully pour the recommended type of transmission fluid into the tube. Be cautious not to overfill; add a little at a time and keep checking the level to avoid spillage.

Step 6: Recheck Fluid Level

After adding fluid, reinsert the dipstick, pull it out again, and check the level until it reaches the “Full” mark.

Step 7: Close and Clean Up

Once the fluid level is correct, securely replace the dipstick. Ensure there are no drips or spills around the engine bay. Close the hood and dispose of any used towels or rags appropriately.

Regularly maintaining your transmission fluid can prevent costly repairs down the line and keep your 1969 AMC AMX running smoothly.
