Buying Guide

Match fittings to your transmission

Confirm AN size or vehicle-specific fittings (e.g., 6AN, 8AN, Ford line shapes) to avoid adapters or leaks

Choose material for durability

Stainless steel braided and reinforced rubber options resist abrasion and heat better than plain hoses

Check length and included fittings

Measure required run and prefer kits with pre-cut lengths or complete fitting sets to simplify installation

Prioritize OEM-style assemblies for direct fit

Direct-fit replacement assemblies reduce installation time and maintain factory routing on specific models

Consider fluid compatibility and ID/OD sizes

Ensure inner diameter and materials are compatible with automatic transmission fluid (ATF) and your cooling system
