Chevrolet Lumina Transmission Oil Line

How to Diagnose Chevrolet Lumina Transmission Oil Line Issues

The only time you'll need to replace a transmission oil line is when it's leaking fluid. Driving with a leaky oil line can get you on the fast track to a lighter wallet. Less fluid means less lubrication, which can be the springboard for all sorts of internal damage. The oil also works as a coolant and helps keep the engine compartment from turning into an oven. As friction and heat increase, your transmission parts will suffer from accelerated wear and tear. Save yourself from a steep bill on your Chevrolet Lumina by observing your car and watching out for these symptoms:

Oil puddles

If you notice drops or tiny puddles of pink or red fluid after your car has been parked for a while, then you've got cause for concern. To make sure, try laying a sheet of newspaper under your car after you park it for the night. Even better, use aluminum foil so you can see approximately how much oil you're losing and how bad the leak is.

The scent of something burning

Sometimes, a leaky oil line won't leave a puddle. This is because the oil never reaches the ground. Instead, it may have landed on the engine block or some other hot surface where it burns up. If you notice the smell of something burning while driving in your Chevy Lumina, this could be why.

Frequent overheating

Since the transmission oil doubles as a coolant, overheating is one sign of a bad oil line. If steam rising from under your hood is beginning to be a common occurrence, inspect along the length of the oil line and its connections for any signs of oil leaking out.

Rapid loss of transmission oil

This is one of the reasons why you should routinely check on your car's fluid levels. On one hand, you can tell if the transmission fluid needs replacing, and on the other hand, it's another way to catch a leak before it causes damage to your Chevrolet Lumina. Watch out for odd and frequent drops in the amount of transmission fluid.

  • Keeping Your Chevrolet Lumina Transmission Oil Line Alive & Kicking 27 February 2013

    This unassuming part is responsible for carrying the transmission fluid in your Chevrolet Lumina, maintaining a cycle that keeps your car running smoothly as you change gears. Eventually, it will need to be replaced as it gives in to wear and tear. Here are some tips on how to delay the inevitable:


    Avoid overheating your car.


    Excessive heat can do terrible things to your car's internals, and it's no different for the transmission oil lines. Aside from exterior damage, the inside of the oil line could suffer as well when the fluid reachs temperatures higher than what the material was designed to tolerate.


    Use the correct fluid transmission fluid.


    Your Chevrolet Lumina transmission system, while mass produced, is built to specific standards. This includes which transmission fluid flows through its veins. There are many different types and grades of transmission fluid, so be sure to check your owner's manual for which one your car is meant to use.


    Keep transmission fluid at the right levels.


    Make a habit of checking your car's fluid levels. This helps you make sure that the right amount of transmission fluid is there to provide lubrication and cooling. It's also a great way to spot leaks, which will result in odd and sudden decreases in fluid level.


    Check for burnt or contaminated transmission fluid.


    When checking your transmission fluid level, you can also inspect the quality of the fluid. A burnt scent is a subtle sign of overheating, while a scent similar to other automotive fluids (ex. coolant, motor oil) could mean that there's a leak or other cause for contamination. Wipe the fluid onto a white piece of paper or cloth to check the color. Black or dark red means that you need to drain and replace the transmission fluid. Fluid that varies in color could be another sign of contamination or degradation, which would mean a replacement as well.


    Make sure everything is a perfect fit.


    Rubbing and collisions with other parts under the hood isn't good for an oil line's longevity. Always use oil lines that follow OEM specifications and are designed to fit under the hood of your Chevrolet Lumina.
