Diagnosis before parts
Many shifting problems start outside the transmission: low fluid from a leak, a failing sensor, a weak battery or a wiring fault. A road test, a computer scan and a fluid check tell us whether the problem is a repair we can make directly or a sign that the transmission itself has failed.
Fluid service on schedule
Transmission fluid cools and lubricates the transmission and wears out with heat. Towing, short winter trips and stop-and-go traffic count as severe service for most vehicles. We look up your manual's interval and use the fluid type it calls for.
When replacement makes sense
If the diagnosis shows internal failure, we explain the replacement options for your vehicle and what each one costs, so you can decide before any work begins.
