1. Assess the Damage:
* Location of the crimp: Determine exactly where the crimp is located. Is it just a small section of the line, or is the fitting itself damaged? This will dictate your repair strategy.
* Line Type: Is it a hard line (rigid metal tubing) or a flexible hose? Hard lines usually require professional repair or replacement, while flexible hoses might be easier to handle with some DIY skills.
* Cooler type: Is it an external transmission cooler or is it integrated within the radiator? This impacts accessibility and the complexity of the repair.
2. Options for Repair/Replacement:
* Option A: Professional Repair (Recommended for hard lines): If the damaged line is a rigid metal tube, the safest and most reliable approach is taking it to a transmission shop or radiator specialist. They have the tools (like flaring tools) and expertise to properly repair or replace the line. This avoids leaks and potential transmission damage.
* Option B: Replacement with Flexible Hose (if applicable): If the damaged section is relatively short and the lines are flexible, you might be able to replace the damaged section with a piece of compatible transmission cooler hose. This requires:
* Measuring: Carefully measure the length of the section to be replaced.
* New Hose: Purchase a suitable replacement hose of the correct diameter and length from an auto parts store. Specify the application (Dodge Ram 1500 transmission cooler line) to ensure compatibility. You'll want to check for fittings that match your existing lines, likely a specific type of AN fitting.
* Clamps: Obtain appropriate hose clamps strong enough to hold the hose securely but not over-tighten and damage the hose.
* Cutting: Carefully cut the damaged section of the hose.
* Installation: Insert the new hose section and secure it tightly with the clamps.
* Option C: Entire Line Replacement (Most robust): For extensive damage or if the fittings are involved, it's best to replace the entire transmission cooler line. This often requires removing parts to access the lines completely. This is not a beginner-friendly project and might require expertise to ensure proper routing and connection.
3. Tools You Might Need (depending on your chosen option):
* Wrench set: For disconnecting lines and fittings.
* Line wrench: Prevents rounding off fittings.
* Hose cutters: If cutting flexible hose.
* Hose clamps: For securing new hoses.
* Transmission fluid: You'll likely need to add some fresh transmission fluid after the repair.
* Shop towels: To clean up any spills.
* Safety glasses: Always protect your eyes.
4. Important Considerations:
* Transmission Fluid Type: Use the correct transmission fluid specified for your Dodge Ram 1500. Using the wrong fluid can severely damage your transmission.
* Bleeding the System: After the repair or replacement, you may need to bleed the transmission system to remove any air bubbles that might have entered the lines. This is often done with a transmission fluid exchange machine or through careful bleeding procedures outlined in your vehicle's repair manual.
* Professional Assistance: If you're not comfortable with this type of repair, especially working with hard lines, it's highly recommended to seek professional assistance to avoid potentially expensive damage to your transmission.
In short: Unless you're experienced with automotive repair, especially transmission systems, it's best to take your Dodge Ram 1500 to a qualified mechanic. Improperly connecting transmission cooler lines can lead to serious transmission problems.
