Automatic Transmission Overhaul

An automatic transmission overhaul requires your existing transmission to be removed from your vehicle, disassembled, and then it is rebuilt by replacing the old and warn parts with new ones. Once reassembled, with new parts, new seals, and new gaskets, your transmission is reinstalled it into your vehicle, filled with transmission fluid, and road tested to check for proper operation. You keep your original transmission, and it works like new. The overhaul can take anywhere from 6 days to a couple weeks depending on the availability of the needed parts.

Automatic Transmission Replacement

Replacing your existing transmission with an identical rebuilt transmission can save you a lot of time. We can remove and replace your existing transmission, and make the necessary adjustments in about half the time. This means you get your car back sooner, and with no more transmission problems!

Servicing your transmission includes replacing transmission fluid, transmission filter, and any needed adjustments. With your transmission pan removed, we will inspect your transmission for signs of wear, that may create potential problems for you and advise you of them. We also check for proper shifting, backup light switch adjustment, shifter adjustments, and passing gear adjustment as part of our automatic transmission service.

Automatic Transmission Repair

65 Thunderbird

Many things can go wrong with a modern transmission, such as modulators, sensors, vacuum lines, cables, bushings, and computer modules. We can diagnose which components are causing you problems, and replace them, to get you back on the road quickly.

When your transmission is not shifting right or slipping, the best thing to do is schedule a transmission diagnostic test, and find out what the problem is. Don’t take the shortcut approach of just changing the transmission fluid, or pouring additives into your transmission.

Automatic Transmission Flush

A Transmission Flush can be performed without removing your transmission, from your vehicle. The biggest advantage to a Transmission Flush over a transmission fluid change, is that we are removing the all old fluid from the cooler, your radiator, your torque converter and your transmission. It is a more complete process that extends the life of your transmission because you are running cleaner transmission fluid. Ask us about a Transmission Flush for your vehicle today.

Automatic Transmission Leak Repair

Are you noticing pink transmission fluid in your driveway? Transmission fluid leaks don’t fix themselves. In fact, they tend to get worse when you ignore them. A small leak can suddenly become a big one that you can’t ignore. If you are noticing transmission fluid drips in your driveway, make an appointment to bring your vehicle in for an inspection. We have a number of ways to determine were the leak is coming from. Many times we can fix the leak without removing your transmission from your vehicle.

Automatic Transmission Computer Diagnostics

Technician Using Computer

Electronically controlled automatic transmissions use a specialized computer, and a series of sensors to let the computer know what your vehicle is doing. These sensors can wear out, and sometimes even the computers fail. We can test your electronic transmission’s computer system (CPU) and sensors, to determine which ones are causing your transmission problems.

Torque Converter Replacement

In an automatic transmission the torque converter functions as the “clutch” between the engine and the transmission. When the torque converter fails, your vehicle will not move. When it is failing you may experience “shuddering” which is the torque converter engaging then slipping, rapidly and repeatedly. Replacing your torque converter does require removing your transmission from your vehicle, so this a good time to go ahead and do a transmission service or flush.

Transfer Case Servicing

4-wheel drive vehicles utilize a transfer case to apply torque to your front wheels. This allows power to the rear wheels and the front wheels at the same time. Just like differentials, transfer cases experience wear, and require regular servicing to help them last longer. If you’re not able to engage your 4-wheel drive, schedule a time to have it checked by our 4-wheel drive specialists.

Clutch Replacement

If you have a manual transmission, you already know that the clutch allows you to be able put your vehicle in gear while the engine is running. Those smooth shifts are because your clutch is slipping against the pressure plate. That slippage is what wears your clutch out. The less you slip your clutch, the longer it will last. When you you need a new clutch, just give us a call, we can get you back on the road fast. You’ll be pleasantly surprised with our service and our prices.
