As recently as a decade ago, a transmission specialist may have only needed to work on 10 different models of transmissions. These models were the mainstream and were easily stocked. Whenever parts were needed, they were accessible and relatively inexpensive. Today, a transmission specialist must keep up with as many as 350 models. This increased variety, along with the growing complexity of transmission technology, means that transmission specialists must have advanced training and continuing education.
Many drivers ignore their transmissions until their is a major problem.
Denial could result in more extensive damage to the vehicle as the problem becomes more severe. If your vehicle's transmission starts sending distress signals, take it in for a diagnosis. Just as you would not expect a doctor to give you a diagnosis over the phone, it is impossible to phone-shop transmission companies for estimates on transmission repair. The transmission repair facility must see the vehicle to begin the diagnostic process. All transmission repair centers should road-test a car first.
