Transmission Repair & Service

Transmission Repair Tigard

A healthy transmission is essential to the performance of your vehicle. At AAMCO, we provide comprehensive external and internal diagnostics to get to the root of your transmission problem. Once we know your car issue, our skilled technicians will work to rebuild or repair your transmission, bringing it back to peak performance.

External Diagnostics

The first step of any transmission repair is a complete diagnosis of your transmission problem. An expert technician will thoroughly review your transmission, checking the level of your transmission, transfer case, and differential fluid, and performing a road test. This test is one of the most important parts of the transmission diagnostics process. Your technician will listen for noises, feel for abnormal vibrations, check the timing and quality of downshifts and upshifts, check drive ranges, and the initial engagements of each gear.

After the road test, your vehicle will be placed on a lift to inspect it for problems external to the transmission. Components that will be examined include:

  • Shift linkage or cable
  • Vacuum connections
  • TV/detent cable/linkage
  • Harness connections
  • Ground connections
  • Mounts
  • Axles and shafts
  • U-joints/CV joints
  • Pan gaskets
  • Wire conditions

Many vehicle owners who believe they have a transmission problem find that their problem lies elsewhere in the vehicle. AAMCO center provide a full range of car repairs. We will never press you into a transmission repair that you don't need.

Computer Diagnostics 

At AAMCO Car Centers, we take advantage of some of the most advanced computer diagnostic equipment in the industry to pinpoint transmission problems. Your expert technician can utilize our diagnostic software to determine if an electronic component is negatively affecting your transmission's performance. This complete test includes:

  • Retrieving trouble codes from your vehicle with the use of a computer system scanner.
  • Comparing the retrieved data against the nationwide AAMCO technical database.
  • Utilizing the AAMCO Kwiktest™ PlusBox to determine if a problem is located inside of a transmission.

After performing this rigorous road testing and computer diagnostics, your technician will have a better understanding of your vehicle issue. Superior technology and highly trained technicians are what sets AAMCO diagnostics apart.

Quality Rebuilds and Repairs

If an AAMCO technician determines that your vehicle does need a repair, you will receive a complete and honest estimate of the work needed. All of our car centers stress integrity in this regard. In over half of the transmission repairs we perform, only minor repairs are needed. If your transmission does require a full rebuild, you can expect only the best materials to be used.

To guarantee our work, we offer some of the strongest warranties in the industry. Our customers can also take advantage of available lifetime warranties for further security. The mutual trust we hold with our customers is why they come back to us for all of their vehicle service needs.
