About Larry Morton's Transmission Service

We opened our doors here in Oregon City over 30 years ago, able to build and repair 14 different transmissions. Today, our team of rebuilders, who specialize in specific transmissions and have over 100 years of combined experience, give us the ability to handle over 300 transmission types, from a 1950 Buick to a 2010 Audi S6 to a TD8E Crawler and most things in between.

We know your time is valuable, and being without a vehicle while you wait on a part can be stressful. Through an extensive in-house parts inventory, we ensure you have the quickest possible turnaround on your repair or custom remanufactured drivetrain component.

We also strive to keep costs down, and that can be difficult if you have to send your parts out to other places for specialty work. Our team has an impressive and varied skill set that we call upon to do many "extras" in-house. To support that work, we have a full machine shop and metal fabrication department onsite to handle simple driveshaft repairs to complete conversions.

Situated 13 miles from downtown Portland, one of the benefits of being outside the city limits is our access to open roads. This allows us to more efficiently test drive your vehicle at different road speeds to better diagnose the issues.

Proudly located in our own buildings in downtown Oregon City on the corner of 6th St. and McLoughlin Blvd.
