Transmission Oil Line
After ahopping for some groceries, you get back in your car and prepare to drive back home. As you back up, you notice a puddle of fluid lying on your parking spot. Concerned, you get out of the car to investigate and you find out that the puddle of fluid has a red color. This, unfortunately, is a symptom of having a leak in your transmission oil line.the component that's responsible for routing the ATF from the transmission to the radiator. Typically located along the passenger side of the vehicle under the hood, this component is constantly subjected to extreme changes in temperature and pressure levels. That's why it's inevitable for the oil lines to eventually face demise and require replacement. If you're dealing with this right now, address the problem immediately. Here's a brief repair and maintenance guide that can help you out.
Tools that you'll need:
- Jack and jack stands
- Line wrench set
- Penetrating oil
- Transmission fluid
- Drain pan
- Metric socket and wrench set
Step 1: To start, set the vehicle to park and turn the emergency brake on. After that, use the jack and jack stands to lift and support the vehicle.
Step 2: Locate the connection points (hose clamps and hard line flared nuts included) of the transmission oil line and spray them with penetrating fluid. Allow the oil to saturate for 15 minutes and use a rag to wipe any excess.
Step 3: After that, pull the oil lines from the radiator and allow the fluid to drip into the drain pan. Depending on your vehicle, you may need to use aeacrewdriver to remove some hose clamps and sockets.
Step 4: Once the fluid is drained, carefully use the line wrench to disconnect the oil line from the transmission and allow the fluid to drip on the drain pan.
Step 5: Find and remove all the transmission line supports on the main part of the frame and replace them if they're damaged.
Step 6: Mount the new transmission oil lines in place and start installation from the bottom of the radiator. Installing some mounting flanges can make this step easier.
Step 7: Next, get the front hoses and reattach them to the radiator nozzles. After that, attach the new line connector nuts by hand before tightening them using heline wrench.
Step 8: When installation is complete, refill the transmission fluid and make sure you put just the right amount.
Transmission Oil Line Repair Tips
- When flushing the transmission fluid, observe if it has a brown color and burnt odor. If it does, you need to check your plates for damage as well.
- During the installation process, you can put some oil on the line gaskets to make them seal better.
- Never reuse old o-rings because they can become hard or brittle. They can also shrink and not seal the new line properly.
- After doing your transmission oil line repairs, make sure you get rid of the waste oil properly. It would be best to take them to reclamation centers for proper disposal.
