About Us

General Maintenance And Repair

Our transmission technicians not only inspect your vehicle to make sure the transmission is in tip top shape but while they are looking for transmission issues they will make you aware of any other issues that they may find.

Any additional services can be performed as requested. Use our shop as a one stop shop. Use us for not only highly complicated things like transmissions, but for general repairs as well.

About our technicians

Our technicians are not paid by job like in other shops. We make sure the technician has the time needed to repair your vehicle properly. The transmission them selves are complex. Our company insures the technicians are supported using current or best technology available. Some of our technicians have been doing this going on 40 years.

Automatic Transmission & Transfer Case

We re-manufacture our own

 3 Year Unlimited Mileage Transmission.

Automatic transmissions are very complicated with today's computer systems controlling them. We also rebuild the valve body in most cases. Our company uses some of the best technology available to identify the cause of future problems by using better quality parts and re-building procedures. Holding this standard gives our company the ability to offer a long term warranty.  

Software PCM Flashing Available

Our company uses the latest equipment available to be able to re program the vehicles PCM/ECM/TCM modules. Most re-flashing prices start at $275.00 and up depending on the vehicles manufactures license fees.


Often times software can cause problems with the vehicles transmission and engine. Many times the vehicle will have software updates that the manufacture later offers. These updates are to correct problems later found as the vehicle ages and the manufactures discover the correction using software updates.
