Transmission Repair & Service

Transmission Repair Technician New BraunfelsJust as a doctor does not treat a disease without properly diagnosing it, AAMCO mechanics will not try to fix a transmission problem before properly diagnosing it. In order to get accurate and reliable diagnoses, AAMCO technicians perform an exclusive multi-point transmission scan service on every vehicle that comes in.

The exclusive Transmission Scan service includes a check of the level and condition of your transmission fluid, a check the level and condition of transfer case and differential fluid when applicable, and a road test that allows technicians to experience any problems firsthand and test the performance of your vehicle. Aspects of performance that the road test will cover include:

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

Once your vehicle has received its initial inspection and road test, your AAMCO technician will put it on a lift and examine the controls under the vehicle. To determine whether the problem is external to the transmission, your technician will inspect:

  • Shift linkage or cable
  • Vacuum, harness, and ground connections
  • TV/detent cable/linkage
  • Engine performance and idle
  • Mounts
  • Final drive
  • Axles and shafts
  • U-joints/CV joints
  • Fluid retention
  • Pan gasket
  • Wire condition
  • Any trouble codes from the computer system

These tests may provide your AAMCO technician with enough information to make a diagnosis and recommend repairs. If, however, the source of the problem has not been found after these tests, further tests can be performed. AAMCO technicians will never recommend repairs before knowing exactly what needs to be fixed.

Computer and Internal Diagnostics

AAMCO experts only fix what needs to be fixed. Our advanced computer and internal diagnostics system is yet another tool that helps us ensure we do just that.

In many of today's vehicles, computers play a vital role in the operation of the transmission. This means that many transmission problems are due to simple computer errors. AAMCO's Computer Diagnostic Service will reveal whether the problem with your vehicle's drivability is caused by a malfunctioning electronic component.

The first step in the Computer Diagnostics Service involves using a scanner to retrieve any trouble codes from any of the critical computer systems in the vehicle. Next, the data is reviewed against AAMCO's proprietary technical database, which is the most complete resource on transmission computer diagnostics there is. Finally, your technician will connect the AAMCO Kwiktest ProBox to determine whether or not the problem is in the transmission computer system.

Your AAMCO technician will also inspect electronic components, solenoids, sensors, and all related wiring. This will be helpful in determining whether an electronic component needs to be replaced or repaired. With these thorough diagnostic techniques and skillful repairs, we can get your vehicle back on the road quickly!

AAMCO has been the most trusted name in transmission diagnostics, maintenance, and repairs for nearly 50 years. This comes from our commitment to providing excellent customer service, accurate diagnoses, and reliable repairs. We always perform our Transmission Scan service before beginning repair work, and we often find that only minor repairs are needed. A competitor with less through diagnostic procedures may end up recommending and performing more extensive repairs than are necessary.

Whenever your AAMCO technician does recommend a larger repair, he will make sure that the job is done right. Only top-quality replacement parts will be used we won't install cheap components pulled from a junkyard. We even stand behind our work with the strongest nationwide warranty in the business, from our basic no-questions-asked nationwide warranty to our iron-clad lifetime warranty.

You can always trust AAMCO to pinpoint your transmission's needs and provide honest and reliable repairs.
