CMOOD 6AN Stainless Braided Transmission Cooler Lines 70" Kit — PTFE-Lined, Universal Fit for Chevy GM Ford

CMOOD 6AN braided stainless transmission cooler lines are a 70-inch universal kit designed to replace stock cooler hoses, increase durability, and improve transmission oil cooling for Chevy, GM, and Ford applications.

If you want a reliable aftermarket replacement for worn or stock transmission cooler hoses, this CMOOD kit supplies two 70" PTFE-lined, stainless-braided lines and a set of fittings to match many popular automatic transmissions. The assembly is built to resist heat, pressure, and corrosion while offering flexible routing options and leak-resistant terminations. It’s intended for enthusiasts, DIY mechanics, and professional shops looking to upgrade cooling plumbing for transmissions like the 4L60E, TH350, TH400, 700R4, 4L65E, 4L80E and similar models.

How do these lines improve transmission cooling performance?

The PTFE (Teflon) inner tube and stainless braid combine to maintain fluid flow and resist deterioration at elevated temperatures. Better heat resistance and reduced permeability help the transmission oil run cooler under load, which supports consistent shift quality and component longevity without guaranteeing specific temperature drops.

• PTFE core minimizes fluid absorption and swelling
• Stainless braid improves heat dissipation and abrasion protection
• 70" length allows flexible routing to aftermarket coolers and remote radiators
• Wide fitting selection reduces need for adapters or additional parts

What vehicles and transmissions are compatible with this kit?

The kit is engineered as a universal 6AN solution for a broad range of American automatic transmissions and turbo setups. It works with many Chevy, GM, and Ford transmissions when paired with the correct adapter fittings supplied in the package.

• Fits Turbo 4L60E, TH350, TH400, 700R4, 4L65E, 4L80E and similar GM units
• Compatible with 200-4R, TR6060 and select Ford boxes like 4R100, 4R70W
• Includes multiple adapters (6AN to NPT/NPS sizes) for varied applications
• Universal design works with aftermarket coolers and remote filter mounts

How straightforward is installation and sealing?

Installation is designed to be user-friendly: the kit includes two long hoses plus a range of 6AN adapters that cover common thread standards. The hose ends are finished with a rubber-covered section to improve sealing and reduce the chance of weeping, but proper torque and thread sealant should be used per vehicle requirements.

• Package includes 2 x 70" 3/8" ID lines and multiple adapters
• Rubber-covered terminations for improved sealing and handling
• 90° fittings included for tight routing near the engine or frame
• Works with thread types: 1/4 NPT, 1/4 NPS, 3/8 NPT via adapters

Will these lines hold up under heavy use and high pressure?

The braided stainless construction paired with a PTFE core is chosen for high-strength and high-temperature environments common in performance and towing applications. The design withstands higher operating pressures than many rubber hoses and resists abrasion, oil exposure, and corrosion, but always follow torque specs and inspect lines periodically.

• Stainless braid improves burst resistance and abrasion protection
• PTFE inner tube resists heat, chemicals, and low-temperature stiffening
• Designed for repeated flexing and vibration in engine bays
• Periodic inspection recommended for fittings and routing clearance

Who is this for: Owners upgrading worn factory transmission hoses, builders fitting remote coolers or aftermarket radiators, and performance drivers who need a durable, flexible 6AN plumbing solution for Chevy, GM, and Ford automatic transmissions. It’s suitable for skilled DIYers and professional installers who will select the correct adapters and follow vehicle-specific installation practices.
