Jim is quite the man of many talents.   He is very involved within his church and in the past few years an active member as a mason.   And if you want a history lesson and a story, he will be happy to give you one.

He and Tom teamed up years ago to make the shop a full service facility and beyond just transmissions.  This the guy for all your electronic issues, A/C servicing, Brakes, Engine work and more.  We don't feel that there is a a guy more talented as Jim.  ype your paragraph here.

Tom Warnke - Owner


112A  N 169 HWY. Smithville  mo  64089​


​Tom was  raised by his grandparents, in Shenandoah, Iowa, to be hard working and honest to the core.


He began in high school working at a local shop.  He then made his way to San Diego and became the top transmission technician in the county, working for 18 years with a local GM dealer.  There Tom became a GM Master Transmission Technician and has never looked back.  In 2013, the dream was to return to the Midwest and open a shop of his own.   And as they say, the rest is history.  

​Then the thought was, why not buy and sell a mechanically sound and budget friendly vehicle.   If you are in need of a quality used car, truck, or SUV,  check out our currentand up comingvehicles.  Also, we are happy to help locate a vehicle at your request.
