CMOOD Transmission Cooler Lines 6AN Braided PTFE 70" — Stainless 2‑Pack for Chevy/GM/Ford, Leak‑Resistant

CMOOD 6AN braided 70" transmission cooler lines are a stainless-steel PTFE hose kit designed to replace factory rubber lines and improve cooling durability and leak resistance for many Chevy, GM and Ford transmissions.

If you want a robust replacement for worn or undersized transmission hoses, this kit supplies two 70-inch stainless-steel braided lines plus a selection of adapters to fit popular automatic transmissions such as Turbo 4L60E, TH350, TH400, 700R4, 4L65E, 4L80E and several Ford models. Built around a PTFE inner core with an exterior stainless braid, the lines are made for higher heat, higher pressure and longer service life than stock rubber hoses.

How will these lines affect transmission oil temperatures?

The tighter core and metal braid help maintain consistent fluid flow and resist expansion under pressure, which aids cooler performance. While the hoses themselves don't actively cool, they reduce flow restrictions and help the external cooler operate more efficiently.

• High-strength PTFE core minimizes swelling and softening under heat
• Stainless braid provides rigidity to prevent hose collapse
• Less internal friction versus degraded rubber helps fluid circulation
• Longer runs (70") suit remote cooler installations without kinking

Will this kit fit my transmission and how simple is installation?

The package includes multiple adapter fittings to match a broad array of transmission ports and aftermarket coolers, making the kit broadly compatible with many GM and Ford transmissions and common turbo setups. Installation is typically a bolt-on replacement, but routing, clamp points and adapter selection should be checked before fitting.

• Includes 6AN to 1/4NPT, 1/4NPS and 3/8NPT adapters for cross-compatibility
• Two 70" hoses provide ample length for front or remote cooler runs
• Black rubber-covered connection ends reduce the risk of leaks at fittings
• Trim and clamp where needed; use proper torque on adapters

How durable and safe are these braided transmission lines?

The combination of a Teflon-like PTFE inner tube and a precision stainless-steel outer braid offers resistance to high temperatures, chemical attack and abrasion compared with plain rubber hoses. Sealed connection sleeves and quality fittings minimize leak points when installed correctly.

• PTFE core tolerates heat and fluid exposure better than rubber
• Stainless braid shields against physical damage and supports bending
• Rubber-covered ends improve sealing and protect threads during assembly
• Designed for high-pressure transmission circuits and demanding driving

What’s included and which adapters help match my car?

The kit ships with two 70-inch lines and a set of six- and quarter-inch adapters to handle a variety of thread standards and fitting angles, so you can adapt to different cooler and transmission ports without hunting for extra parts. The hardware selection reduces installation guesswork for many common applications.

• 2 × 70" braided 6AN hoses with 3/8" inner diameter
• 4 × 6AN to 1/4" NPT adapters and 2 × 6AN to 1/4" NPS adapters
• 4 × 90° 6AN female-to-male swivel adapters for tight clearances
• 2 × 6AN to 3/8" NPT adapters for additional fitment options

Who is this for? This CMOOD transmission line kit is suited for DIY mechanics, performance enthusiasts and shop technicians replacing aged rubber lines, routing fluid to an external cooler, or upgrading plumbing for turbocharged or heavy-duty applications. It’s a practical upgrade for owners of Chevy, GM and Ford vehicles with the listed transmissions who need longer, more heat-resistant lines and a broad set of adapters for reliable connections.
