Specifications

Q: Why should I replace the OEM transmission lines?
A: The stock quick-disconnect fittings are prone to loosening, leaking, and cracking under high heat and pressure. This kit eliminates those issues with a more secure threaded connection.

Q: Will this kit reduce transmission temperatures?
A: Yes. The larger-diameter braided hoses improve fluid flow, allowing better heat dissipation through the cooler, which helps lower transmission temperatures.

Q: Do I need to modify my truck to install this kit?
A: No major modifications are required. The kit is designed to fit the factory transmission and cooler locations.

Q: Is this kit compatible with the factory transmission cooler?
A: Yes, it is fully compatible with the OEM cooler.

Q: Can I install this kit myself?
A: Yes, but installation can be tricky. OEM lines are often difficult to remove as a single piece. It may be necessary to cut the factory line into sections for easier removal.

Q: What are the hoses made of?
A: The lines use high-pressure CPE braided hoses that are heat and abrasion resistant, ensuring durability in harsh conditions.

Q: Are the fittings reusable?
A: Yes. The billet aluminum adapters are reusable and serviceable.

Q: Will this kit work with heavy towing or off-road applications?
A: Absolutely. This kit is designed for high-demand situations like towing, hauling, and off-road driving.

Q: What happens if one of the hoses gets damaged?
A: Unlike OEM lines, you don’t need to replace the entire assembly. You can replace only the damaged section.

Q: Do I need special tools for installation?
A: Basic hand tools are sufficient. Cutting tools may be required to remove factory lines if they are stuck or routed tightly.
