Our Services Modern automatic transmissions have become very complex with lock up torque converters, computer-controlled shift patterns and hydraulic valve bodies designed for maximum economy with low exhaust emissions. Four speed overdrive transmissions are now common on today s modern, fuel-efficient motor cars. Servicing an automatic is important preventative maintenance. Low oil level indicates a leak or malfunction and is often your transmissions way or crying for help . Transmission fluid should smell and look clean and red, not burnt and brown.
Dirty oil indicates a problem.
Oil should be checked in neutral with engine hot and idling. HEAT burns the oil, cooks the seals and causes early wear of bands, bushes and clutches. Transmission temperatures can be kept down by changing down on long hills and not using the engine to hold on an uphill stop sign or traffic light. Small changes in your car s operating feel should be diagnosed imediatley. Late or early shifts, slipping or noises could become expensive if left.
