ACDelco Transmission Oil Cooler Hose Assembly

ACDelco Transmission Oil Cooler Hose Assemblies: OE Precision for Your GM Vehicle

When your automatic transmission depends on a steady flow of cooled fluid to stay protected, the hose assembly routing that fluid to and from the cooler is a critical link in the chain. A cracked, softened, or leaking transmission oil cooler hose can allow fluid to escape or degrade under heat and pressure — leading to overheating, slipping, and ultimately, costly transmission damage. That's why choosing the right replacement matters, and few names carry more authority here than ACDelco.

GM Original Equipment — Not Just "Compatible"

ACDelco GM Original Equipment Automatic Transmission Oil Cooler Hose Assemblies are GM-recommended replacement components for automatic transmission/transaxle and drivetrain systems. This distinction is significant: rather than being reverse-engineered aftermarket alternatives, GM Genuine Parts and ACDelco Original Equipment are the true OE parts installed during production or validated by General Motors, designed and engineered to meet rigorous standards set by General Motors.

This original equipment assembly provides the same performance, durability, and service life you expect from General Motors. For GM vehicle owners — whether driving a Chevrolet Silverado, GMC Savana, Saturn Vue, or Buick LaCrosse — this translates to a part that slots in exactly as the factory intended, with no adaptation required.

Construction and Fit You Can Count On

ACDelco transmission oil cooler hose assemblies are built using a combination of rubber and steel construction, designed to handle the thermal cycling and fluid pressures present in an automatic transmission cooling circuit. Each unit is manufactured to GM OE specification for fit, form, and function , covering both inlet and outlet positions to ensure a complete, leak-free repair. The precision dimensions — including carefully controlled inside diameters and connection geometry — mean there's no guesswork in fitment.

ACDelco's Tiered Quality Lines

ACDelco structures its parts catalog to give technicians and DIYers the right option for every situation. ACDelco Gold parts are high-quality alternatives to OE parts, manufactured to meet expectations for fit, form, and function, making them a smart choice for GM vehicles and many makes and models. For hose assemblies falling under the GM Original Equipment banner, ACDelco's GM OE auto parts are the original parts for GM vehicles and meet or exceed GM OE specifications.

ACDelco is the premier supplier of GM Original Equipment automotive replacement parts, offering nearly 90,000 auto parts across 37 product lines available globally. That breadth of catalog depth means ACDelco can supply transmission cooling components across a wide range of GM model years and platforms.

Why It Matters for Your Transmission

Transmission fluid that runs too hot breaks down rapidly, losing its ability to lubricate and protect clutch packs, bands, and bearings. A healthy cooler hose assembly keeps fluid circulating efficiently through the external cooler — typically integrated into or alongside the radiator — before returning it to the transmission sump at a safe operating temperature. Replacing a worn hose assembly with an ACDelco unit restores that thermal management path to factory standards, protecting a component that can cost thousands of dollars to rebuild or replace.
