Automatic Transmission Oil Tube Assembly — Cooler Feed Line 🛠️

This precision steel line routes ATF between the gearbox and the cooler. It keeps fluid moving, removes heat, and protects clutches, bearings, and seals. A healthy line means stable pressure, clean shifts, and long transmission life. Perfect fit, factory bends, and correct flare ends deliver a leak-free install and OEM performance.

Why you need this part 🛢️

ATF must circulate through the cooler to stay in the safe temperature zone. This tube ensures steady flow, correct pressure, and reliable lubrication under towing, off-road, and daily use. It is a core piece of the transmission cooling system.

How it works 🔧

The pump sends hot ATF through this rigid line to the radiator/aux cooler. After shedding heat, fluid returns through the paired line. Double-flare ends, sealing washers, and brackets prevent leaks and vibration. Coated steel resists rust and road salt.

If the line is damaged ⚠️

• ATF leak, red spots under vehicle
• Harsh or slipping shifts, delayed engagement
• Overheat warning, burnt smell, dark fluid
• Possible limp mode and loss of drive
• Fire risk if spray hits hot exhaust

Tech tips 🛡️

Use line wrenches, replace seals, torque to spec, and route in factory clips. After install, warm up, cycle gears, and recheck ATF level. Inspect cooler ports and flush any debris for best results.
