If you've already installed an auxiliary transmission cooler and are looking to upgrade your lines to a stronger and safer setup, this kit is for you.

Note: Will work on any cooler with 5/8x18 inverted flare fittings.

Please check compatibility tab prior to ordering.

• (2) 5/8x18 Inverted flare to -6AN cooler fittings (Zinc coated steel)
• (2) Transmission Fittings to -6AN, includes supply and return fittings (4L80e & 1/4 NPSM - anodized steel, all others - billet aluminum)
• (2) 10ft -6AN nylon braided lines

FOR 4L80E KITS

• (4) 90 degree -6AN swivel ends (required on both ends due to lower grill valance)

• (2) straight -6AN swivel ends (transmission end)

Note: This kit is designed mostly for aftermarket engine and transmission setups. The lines will come cut 10' in length with only one fitting end installed. This is so you can cut and route the lines to your specified lengths and requirements.
