Is your transmission slipping? There is a chance that a transmission service will fix the problem. But there are no guarantees, this is beacause the oil in your car's transmission does play a role in how well the clotches hold. And over tiem the oil can begin to wear out. Though changing the oil won't help if the clutches are worn out. Once that happens the only option is to rebuild the transmission. There's almost no way to be sure whether changing the oil will save your transmission or just waste your money. But your local Autobody shop can help you to improve these odds, by performing thorough road tests, dropping the pan to examine the transmission's condition, and using a complete computer scan. These will help pinpoint the problem at hand and get you back on the road. In many cases all you'll need is a simple reapir. Because today's transmissions are tied into the rest of the vehicle's systems a simple inexpensive senor repair may correct what seemed to be the problem.
