Description
Keeps Transmission Fluids Cool. Your transmission oil cooler is designed to cool down transmission fluid as it cycles through your transmission to keep it well lubricated. However, a broken or cracked oil cooler line could leak and leave your engine liable to catastrophic damage. This Automatic Transmission Oil Cooler Line offers a direct fit replacement for a damaged line in your Silverado 1500 and keeps your engine and transmission running their best.
Rubber and Steel Hose. This transmission cooler line consists of a steel tubing with a rubber cover designed to insulate heat and handle high temperatures without cracking or deforming.
Direct Factory Replacement. This transmission cooler line offers a direct fit replacement, utilizing the same male connection ends at both ends of the line for a quick replacement. Installation is relatively easy, though professional assistance is recommended for proper assembly.
Limited Lifetime Warranty. A limited lifetime warranty backs this product against manufacturing defects for the life of its purchase.
Application. This Automatic Transmission Oil Cooler Line is compatible with all 1999-2006 Chevrolet Silverado 1500 models.

Almost perfect fit it's a little offset compared to the original line so it doesn't sit in the retaining clip. Other than that good buy, I'm sure I saved some $$ by not going to the shop. Took a little while due to first time removal and install.

Definitely an upgrade over stock. Install was easy. This is how it should have been from the factory in my opinion.
