Automatic Transmissions

Automatic Transmissions

While we are complete drivetrain specialists, automatic transmissions are the core of our business because most cars and now many trucks use automatic transmissions. We service, rebuild and replace car, and most truck and RV transmissions.

We are automatic transmission troubleshooting experts. What you may think is an automatic transmission problem is not a transmission problem at all. A faulty computer chip, an intermittent "prndl" switch (park-reverse-neutral-drive-low), a leaking vacuum line, and many other seemingly unrelated problems might be diagnosed as a transmission problem by others.

We offer a no-charge diagnosis while-you-wait, saving you time and money. So often, people come to us thinking they have a transmission problem when they don't. Why risk a wrong diagnosis when getting it right from the experts is free?

Rebuilt Transmission

Pre Rebuilt (Remanufactured) Transmissions

Why consider a used transmission when you can get an economical completely remanufactured transmission with OEM or better parts with a nationwide warranty too? Because we have a huge inventory of rebuilt transmissions and automatic transmission parts, we can ship out of inventory, repair or rebuild transmissions fast.

With a pre-rebuilt transmission, we don't have to take your transmission apart to find out what is wrong. We simply replace yours with a transmission out of inventory. No surprises after we get inside. No guesses as to the cost. Simply "Peace of Mind" knowing everything got fixed. And... with a 3 year 100,000 mile Nationwide Warranty too!

Manual Transmissions

Manual Transmissions

When you have a problem with your car’s transmission, our technicians are manual transmission experts. We know how to fix them when they stop working.

Most manual transmission shifting problems aren't with the transmission itself, but more often with a clutch, flywheel or clutch master cylinder.

If your car’s manual transmission is having problems, from grinding gears to not moving at all we can diagnose it and let you know exactly what it’ll take to get you back on the road and shifting gears again.

Clutch Replacement

Clutch, Pressure Plate, Flywheel Resurfacing and Balancing

Most manual transmission shifting problems aren't with the transmission itself, but more often with a clutch, flywheel or clutch master cylinder.

When we replace a clutch, we resurface and balance the flywheel at the same time.

Bad pressure plates and time cause flywheels to warp. Resurfacing insures the longest life for your new clutch.

Of course, we only use the highest quality parts and our transmission experts examine and diagnose any other possible issues for you while we have it apart.
