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.
