A transmission oil line is there to connect your car's transmission to its radiator. Without it, your engine compartment would be a hot cooking pot of disaster. It is a fairly simple looking part. But choosing the right transmission oil line is not as easy. Here are still a few things you have to know when buying a new one for your car.
- Make sure that your transmission oil line is approved for use with transmission/hydraulic fluids. Hoses or lines that are of substandard quality will not be able to work effectively. In some extreme cases, your transmission fluid can even break down or melt your oil lines if they are not durable enough.
- Purchase transmission oil lines from trusted brands. Although there is no real preference when it comes to branded oil lines, it is still best to get one from a supplier that you know and trust. Generic types might be cheaper, but branded transmission oil lines ensure that it matches the form, fit, and function of your original part.
- Install rubber transmission oil lines instead of metal ones. Although some metal type lines, especially zinc-coated steel, are more corrosion resistant, they are actually harder to install. In order to efficiently use metal transmission lines, mechanics put small flairs at the end of the lines and sandpapers the surface to give it a good seal. But with a rubber-type transmission oil lines, you don't have to do all of those. You simply need to clamp them in place to ensure a good fit.
- Check the warranty of your transmission oil line. The standard term of warranty is 12-month or 12,000-mile. Don't settle for anything less than that. Also look at the other conditions of your warranty to make sure you get the most value out of what you paid for.
- Don't purchase aftermarket transmission oil lines. It is always recommended that you replace your damaged transmission lines with a new, complete assembly. This part is very sensitive and requires a perfect fit to ensure it functions well. So by purchasing lines that follows the OE design you know that there is no room for gaps and leaks.
- Don't shortcut replacing your damaged transmission oil lines by reinstalling old parts or installing hose clamps to cover the leaks. This can greatly reduce the part's life and could compromise the transmission.
- Don't install new transmission oil lines without replacing fittings as well. It is not enough to get a good working transmission line. You should also ensure that connection to the engine and transmission is of the best quality. This will help you get the most efficient results when it comes to your transmission system.
