The Right Diagnosis Can Save You Time and Money

If you hear noises when the transmission is shifting, your transmission seems to shift erratically, or if you experience any of the other problems listed above, don't just go to a general auto repair shop - you should have your vehicle checked out by a transmission repair specialist immediately. If caught early, some problems can be resolved with an adjustment or a minor auto repair that does not require removal of the transmission from your vehicle, saving you the cost of a transmission overhaul.


Proper diagnostic testing of your vehicle is necessary to determine whether a transmission problem exists and where that problem might occur - inside or outside the transmission. Our certified technicians are trained in the latest diagnostic equipment and software to properly distinguish between major and minor problems so they can understand any transmission problem and replace only what needs to be replaced.


With today's more complex, computer-controlled transmissions, it takes a specialist to diagnose and troubleshoot a transmission problem correctly. Accurately troubleshooting and getting the diagnosis right to determine if it is even necessary to rebuild the transmission can save you a lot of money on your auto repair. We spend the time needed to understand any transmission problem and to let you know where you stand so you can decide what course of action is best for you. You owe it to yourself to go to Winchester Transmissions & Auto Service.
