External Diagnostic Service

The Heads Up Automotive External Diagnostic Service is the best transmission checkup available anywhere. Our technicians can get to the bottom of any transmission problem. With today’s more complex, computer-controlled transmissions, it takes a real expert to be able to diagnose a transmission problem correctly.

Getting that diagnosis right can save you a great deal of money.

The Heads Up Automotive External Diagnostic Service is a systematic and comprehensive external evaluation of the overall performance and condition of your transmission.

  • A trained technician will check the level and condition of your transmission fluid:
    • A low fluid level may indicate a leak
    • Contaminated fluid has water or particles in the fluid.
    • Burnt fluid indicates damage from overheating.
    • Varnished fluid has been overheated repeatedly.
    • Normal fluid is reddish-brown and translucent, depending on transmission type, with no particular odor.
    • The technician will also check the level and condition of transfer case and differential fluid, where applicable.
  • The technician takes your car on a road test, to experience first-hand any problems you have noticed, and to evaluate your car’s performance.
  • Your vehicle will be placed on a lift to inspect the controls under the vehicle for any possible cause of the problem external to the transmission.
  • Finally, the technician will scan the computer for trouble codes*.

From these tests, the expert transmission technicians at Heads Up Automotive can determine what type of problem you might have, and make a recommendation for whatever service is necessary.

* Initial electronic scan is free of charge. Additional computer diagnostic charges are likely to apply.
