Proper care includes regular oil and filter changes, checkups of engine performance, and periodic cooling system maintenance. If you notice that the engine is using oil, has problems with oil pressure, the coolant temperature has risen, or engine performance is not up to par, have the problems looked into as soon as possible. The AAMCO 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 AAMCO centers can determine what type of problem you might have, and make a recommendation for whatever service is necessary.
