Transmission Repair & Service

Transmission Repair Technician San AntonioTxAAMCO of San Antonio insists upon making the right transmission repairs every time, and that means making the right diagnosis every time. In order to do this, we put every car through our exclusive multi-point transmission scan service before starting any transmission repairs.

Our exclusive transmission scan service includes a check of the level and condition of your transmission fluid, as well as a check of the level and condition of transfer case and differential fluid where applicable. The process also includes a road test, which allows our technicians to experience any problems that you have noticed and evaluate the vehicle's performance in regards to:

  • Initial engagements
  • Each drive range
  • Upshift timing
  • Upshift quality
  • Downshift timing
  • Downshift quality
  • Passing gear
  • TCC engagement
  • Neutral
  • Reverse
  • Noises
  • Vibrations
  • 4x4 performance
  • Park-hold

An AAMCO of San Antonio technician will then place your vehicle on a lift and inspect the controls under the vehicle to check for any problems outside of the transmission. The inspection will cover:

  • Shift linkage or cable
  • TV/detent cable/linkage
  • Vacuum, harness, and ground connections
  • Engine performance and idling
  • Mounts
  • Final drive, axles, and shafts
  • U-joints/CV joints
  • Fluid retention
  • Pan gasket
  • Wire condition
  • Trouble codes scanned from the computer

This inspection will allow your AAMCO technician to diagnose just about any problem with your transmission, but it is not the only option. If the inspection does not lead to a conclusive diagnosis, we will work to find out exactly what the problem is before ever recommending a transmission rebuild.

Computer and Internal Diagnostics
The nest level of our diagnostics process is our advanced computer and internal diagnostic test. Quite often, transmission problems in today's high-tech cars are related to the onboard computer. For example, the computer may be sending the wrong information to the transmission about how it should be running.

The AAMCO Computer Diagnostic Service will determine whether your transmission problems stem from an issue with an electronic component by using a computer system scanner to retrieve any trouble codes in order to find any probable causes. All major computer systems will be checked, as a wide variety of them can cause problems with drivability.

The data pulled from the computer systems will then be run through our proprietary AAMCO technical database. This database is the most comprehensive resource available when it comes to transmission computer diagnostics.

Your AAMCO technician will then connect the AAMCO Kwiktest™ PlusBox to see whether the problem is inside or outside of the transmission in the computer system. He will also check the electronic components, solenoids, sensors, and al related wiring.

Having completed these diagnostic tests, your AAMCO certified technician can determine whether any electronic component needs replacing and recommend the appropriate service. Our thorough diagnostic process is what sets AAMCO apart from the competition-we are committed to performing only the repairs you need so that you can get back on the road as quickly as possible.

AAMCO has been the trusted authority on transmission diagnostics, service, and maintenance for nearly 50 years. We always perform our Transmission Scan diagnosis before starting repairs, and we often find that only a minor repair is required. We never try to sell you services you don't need.
