When automatic transmission oil cooler lines fail, the only fix is a quality replacement. Dorman produces a full line of direct-replacement transmission lines for most vehicles on the road today. Our trans lines match the factory fit for a dependable installation and are made from tough, durable materials to deliver reliable performance for years, backed up by a limited lifetime warranty.

Lorem ipsum dolor sit a met
Transverse-mounted all-wheel drive systems rely on compact power take off (PTO) assemblies to transfer power to the rear axle. Our line of newly-manufactured PTOs for select Ford, Lincoln and Mercury vehicles are direct replacements for factory units that have failed from leakage or internal wear. They bolt right into place without the down time of rebuilding the original.

Engaging four-wheel drive no longer requires shifting a lever. It all happens with the push of a switch. But the actuators that now do the actual shifting wear out with use, preventing 4WD from engaging. Dorman has a lineup of direct-replacement 4WD electric and vacuum-operated actuators, shift forks, transfer case motors and more to keep four-wheel drive systems operating as they were designed, as well as select OE FIX solutions that correct common problems in certain OE designs.

Repairing a drive shaft often means sending a vehicle to a driveline specialist with the experience and special equipment required to press in new U-joints and balance a rebuilt shaft. We offer ready-to-install drive shafts for 98% of vehicles on the road in North America. Each one is made from 100% new components including serviceable U-joints and arrives pre-balanced for a quick installation.
