Bring Your Car In For a Transmission Diagnostic

A tranmission rebuild may be exactly what your car needs, depending on your situation. The transmission of your car is among the most complex and essential components of your vehicle, and when the transmission breaks down, so does your vehicle. But you may be wondering whether your car needs to be repaired, replaced or rebuild, and you’re probably stressed out over the process, too. At Advance transmission, we not only strive to provide quality service for your vehicle, but absolute clarity of communication, and in that spirit, we will now explain the difference between a repair and rebuild and when your transmission may need a complete rebuild.

The first step is knowing exactly what is wrong with your vehicle, and the problem may not have anything to do with the transmission! That’s why you should have an expert auto mechanic take a look at your car and run a thorough diagnostic before making drastatic repairs.

Once you have determined that the problem with your vehicle is the transmission, you’ll need to decide the best course of action: to repair, rebuild or replace. At Advance Transmission, we can do all three, but we want to educate you on the best course of action for your vehicle.

How a Transmission Rebuild differs from a Transmission Repair or Replacement

A transmission rebuild is a kind of half-step between a repair and a complete replacement. In a repair, only the minimum necessary parts are replaced to make the car work again.  Often a simple “repair,” as we’ve defined it, is not possible because too much damage has been done to the transmission and needs to be removed and rebuilt to function properly again. If you research transmission repair, you may find a lot more information about rebuilds and replacements instead.

A transmission replacement is more or less like it sounds: the transmission is replaced by having it remanufactured at the factory level, almost as though it was being build for a new car. This can be the best and only option is the damage to the transmission is severe, but there is another course of action: a transmission rebuild. This involves removing and disassabling the transmission, cleaning it thoroughly, and then replacing all the necessary parts before carefully reassembling it. This process can make your transmission nearly good as new and save you the cost of a complete replacement!
