Summer heat can cause transmission components to wear and begin to fail. Maintenance can prevent it and we suggest you bring your vehicle in regularly for service and fluid changes. You probably know to change your oil every 3000 miles, and under heavy-duty use, some manufacturers suggest changing transmission fluid every 15,000 miles. Service intervals for an automatic transmission vary from every 30,000 miles … to never. The typical service interval is 60,000 to 100,000 miles. Changing it more often does no harm. www.cartalk.com/content/service-your-car-14
If you notice any of these issues with your vehicle, have it checked before it fails:
That spot under your car that you noticed awhile back? If you are leaking any fluids you should have it checked out. Transmission fluid is bright red and sweet or tart smelling usually and unlike motor oil it is not consumed during the operation of the vehicle. If your fluid is low, it is likely due to a leak.
The majority of newer vehicles have sensors that will let you know if the temperature of the transmission fluid is hotter than normal. It is one of the most comon dashboard warnings and if you see this light up on your vehicle, check your transmission fluid and engine coolant levels immediately. Check with your owners manual (or with us) to know what your dashboard indicator lights refer to.
Dipstick Location, what to check for
Also, know where the transmission dipstick is in your vehicle in order to check it as well. It is one of the easiest and quickest ways to get a feel for the health of your transmission – and you should check it while the engine is warm and still running. Rub the fluid between your fingers and it should be slightly pinkish and almost clear.
If it looks brownish and smells like burnt toast, it is no longer able to do its job and could mean your transmission is burning as well. This could mean a complete transmission rebuild for your. And yes, we do can do complete transmission rebuilds here.
If you are hearing buzzing, humming or the vehicle shimmies when changing into a different gear, the clutch or transmission may be failing. A delay or lack of response during acceleration can also indicate a transmission beginning to fail.
