Diagnostic Services and Multi-Point Inspection


Fixing your transmission right starts with correct diagnosis of the problem! We perform our exclusive Apollo Transmission Multi-Point Inspection service on every vehicle before we do any transmission repair.

Technology and expertise helps us to pinpoint the root of your transmission problems. We repair only what needs fixing and nothing more. Most of the time, transmissions only require minor repair. Our thorough diagnostics services are part of why Apollo Transmission has been a trusted name in transmission repair for over 25 years.

Our exclusive Multi-Point Inspection & Diagnostics Services includes all of these checks:

  • Check the level and condition of your transmission fluid
  • Check the level and condition of transfer case and differential fluid, where applicable.
  • Perform a road test to experience first-hand any problems you have noticed and to evaluate your car's performance including:​
    • Initial engagements
    • Each drive range
    • Upshift timing
    • Upshift quality
    • Downshift timing
    • Downshift quality
    • Passing gear
    • TCC engagement
    • Neutral
    • Reverse
    • Noises

Your vehicle is then placed on a lift to inspect the controls under the vehicle and identify possible causes of the problem external to the transmission including:

  • Shift linkage or cable
  • Vacuum connections
  • TV/detent cable/linkage
  • Engine performance
  • Harness connections
  • Ground connections

At Apollo Transmission, our expert technicians diagnose many transmission problems through this extensive external check as part of our process in recommending necessary repairs. But However, our diagnostic services don't stop there. Even if an initial check fails to diagnose the issue, we refrain from recommending transmission work until we know exactly what is causing your problem.

Computer and Internal Diagnostics 
Our advanced computer and internal diagnostics are the next level of technology. They help Apollo technicians to ensure that they only repair what needs fixing. Many transmission problems start in the computer system of today's highly technical, computer-controlled vehicles. If your transmission receives the wrong signals from this computer system, Apollo's computer diagnostic service can identify whether an electronic component is affecting your transmission's shifting or overall performance. All critical computer systems in the vehicle are checked for trouble codes, since a variety of systems could cause drivability issues. The service includes:

  • Using a computer system scanner to retrieve trouble codes and determine probable causes.
  • Reviewing the computer system data against our proprietary Apollo technical database - the most extensive transmission computer diagnostic source available anywhere.
  • Connecting the Apollo Kwiktest™ PlusBox to see whether the problem is inside or outside of the transmission in the computer system.

Your certified Apollo center technician will also:

  • Check the electronic components.
  • Check the solenoids and sensors.
  • Check wiring that affects the transmission, solenoids and sensors.

Your Apollo Transmission certified technician can then determine if an electronic component or part needs to be replaced, and recommend necessary service. This comprehensive diagnostic approach that sets apart. We only recommend repairs that you actually need and your car, truck or SUV is back on the road as soon as possible.
