How to check and refill transmission fluid on a 1970 Plymouth Hemi 'Cuda?

Ensuring the transmission fluid in your 1970 Plymouth Hemi 'Cuda is at the correct level is crucial for maintaining smooth and efficient operation of the vehicle. Low or old transmission fluid can result in various issues such as sluggish shifting, slipping gears, or even transmission failure. Here’s how to solve this issue:

Step 1: Prepare Your Vehicle

Before you begin, make sure the car is parked on a level surface and the transmission is warmed up. You can do this by taking it for a short drive. This helps to get an accurate reading of the fluid level.

Step 2: Locate the Transmission Dipstick

Open the hood of your car by pulling the hood release lever, which is usually found under the dashboard. Prop the hood securely with the hood prop rod. Locate the transmission dipstick, which is typically found towards the back of the engine bay near the firewall. It should have a brightly colored handle, often red or orange, making it fairly easy to identify.

Step 3: Check the Fluid Level

With the engine idling and the car in “Park” or “Neutral,” remove the dipstick. Wipe it clean with a lint-free cloth and reinsert it fully, then remove it again to check the fluid level. The dipstick will have indicators marked "Full" and "Low" or "Add." The fluid should be at or near the "Full" mark when the engine is warm.

Step 4: Observe Fluid Condition

In addition to checking the level, take a moment to observe the condition of the fluid. Healthy transmission fluid should be a clear red or pink color and have a slightly sweet smell. If the fluid is dark, dirty, or has a burnt smell, it may be time to replace it.

Step 5: Add Transmission Fluid

If the fluid level is low, you’ll need to add more. Locate the transmission fluid filler tube, which is usually the same tube the dipstick fits into. Using a funnel, carefully add the recommended type of transmission fluid for your 1970 Plymouth Hemi 'Cuda in small increments, rechecking the level with the dipstick after each addition until it reaches the "Full" mark. Be cautious not to overfill, as too much fluid can also cause issues. Typically, the recommended fluid type is Dexron II.

Step 6: Recheck and Clean Up

After adding the necessary amount of fluid, recheck the level one last time to ensure it is correct. Once you’re satisfied, securely replace the dipstick. Close the hood and ensure everything is cleaned up and tools are put away.

Following these steps will help keep your '70 Plymouth Hemi 'Cuda running smoothly by maintaining the appropriate transmission fluid level and condition. Regular checks and maintenance are key to a well-functioning vehicle.
