6 Reasons You Should Replace Your Transmission Line

6 Reasons You Should Replace Your Transmission Line

2nd Mar 2022

Your vehicle’s transmission lines are among the most important yet overlooked parts under the hood. Also called transmission cooling lines, they connect the transmission and radiator and help keep the system cool. Transmission lines are made of rubber and metal, like aluminum. As your vehicle is running, the lines transfer hot transmission fluid to the radiator — where it can cool — and back to the transmission again.

It helps to know when you should replace your transmission lines to keep your vehicle running smoothly. If damaged or worn, they’ll create bigger, more expensive problems in your vehicle’s system. That’s why the team at LinesToGo is here to share six reasons you need to replace your transmission line.

Your Gears Are Slipping or Won’t Shift

One of the most common issues that drivers run into is gear trouble. If your gears are slipping (unable to stay in gear while driving) or you’re having difficulty shifting gears, take a look at your transmission lines. While low transmission fluid levels are often the cause of these issues, damaged transmission lines could be the culprit as they influence the transmission fluid. Your vehicle needs transmission fluid to lubricate its gears, but that can’t happen if the transmission lines aren’t properly transporting the fluid.

Your System Is Overheating

Remember that transmission lines help keep the transmission system cool by transporting fluid between it and the radiator. If your system is overheating or you notice a burning odor, your transmission lines may not be functioning properly. Damaged or worn cooling lines are typically the cause, and you’ll need to buy new transmission lines to correct the problem before it gets worse.

Your Vehicle Is Leaking Transmission Fluid

Leaks are a telltale sign of a problem within your vehicle. If you notice red-colored transmission fluid leaking, you can guarantee that your system needs repairing. Another way to tell is if your fluid levels are abnormally low, so be sure to check on them frequently. It’s common for damaged transmission lines to cause a leak, so it’s wise to look there first when diagnosing what’s wrong.

Shifting Gears Causes Loud Noises

Shifting gears should be a relatively quiet process. When your ears are met with a loud scratching or grinding noise when shifting gears, that indicates your transmission isn’t lubricated enough. Transmissions are at their loudest after starting up and shifting into park, so yours shouldn’t suddenly get louder or make additional noises at other times. If you replace your transmission lines, the noises should stop.

Your Check Engine Light Is On

It’s possible to miss or ignore some signs that you need new transmission lines. But fortunately, you should be able to rely on your check engine light to let you know if any arise. The light can come on for many reasons related to your transmission and cooling lines, including:

  • Transmission is overheating
  • Transmission lines are clogged or not functioning properly
  • Low transmission fluid

There Is Visible Damage to Your Lines

It’s practical to inspect your transmission lines on occasion. If you notice damage or wear and tear, it’s recommended that you replace them. Visible flaws, like cracks or holes, can quickly lead to leaks. Check on the connecting parts, too, such as the edges of the radiator, because they can break or corrode.

So, how do you know when to replace your transmission lines? Visible damage, slipping gears, and grinding noises are just a few reasons that’ll tell you it’s time.
