About Us

Located in Concord, NC.  My specialty is the early Hydramatic transmission, Jetaway transmission, ST300 transmission, Roto 10 transmission, and Power Glide (both cast iron and aluminum) transmission (and the early Rolls Royce Hydramatic), ST300, and Turboglide. Founded on the idea of helping owners continue to enjoy their GM (or other brand) Classic Car or Truck that has a Hydramatic.  Provide OEM based professional and specialized transmission overhaul that keeps your vehicle driving. 

I personally disassemble, inspect, repair, final assemble, and final adjust.  Work is never farmed out.  Parts are sourced from reputable suppliers. All internal gear train and case parts are thermal cleaned.  Your transmission gets a 100% tear down.  Valve assemblies are hand cleaned, inspected and pre-lubed.  All servos are 100% disassembled and inspected.  A triple inspection is provided (one at initial tear down, one after thermal cleaning, one during reassembly).  All issues are noted with digital photos sent to the owner.  OEM torque values are followed, endplay is set to spec, rotation test performed, 100% air test on all clutches and band servos, Band adjustment is performed using OEM tools and procedures.  External gaskets are double sealed.  

I have years of experience repairing Hydramatic transmissions.  Factory trained, years of dealership experience focused on automatic transmission service, diagnosis and repair.  

Do not hesitate to contact me with a question about your transmission or request an estimate - I am glad to be of service.

Located in Concord, NC 28027 (near Charlotte Motor Speedway).  You can ship or drop off your trans yourself.
