  We are a family owned and operated shop continuing a family tradition started by Lee Thomas here in Kelso in 1960.

  We specialize in the maintenance and repair of automatic transmissions, providing honest, quality service at fair prices.

  Our story -

  Lee & Linda Thomas opened Lee's Automatic Transmission Service in West Kelso in 1960.  In 1969 they moved the transmission shop business here to 404 N Pacific Ave. and continued to serve the community until Lee's passing in 2002.  The shop continued in business being run by their son-in-law until late 2011.

  Al Thomas, (one of Lee's sons and Herb's brother), opened Al's Automatic Transmission in St. Helens, OR.  in 1980 and ran it with his wife until 1984 when they opened a new shop, Tigard Transmissions in Tigard, OR.

  Herb took over Al's Automatic Transmission in August of 1984 and we ran it until April of 2012, serving the community for 28 years.

   Herb's son, Gannin Thomas, has continued the family tradition into the 3rd generation establishing his own shop, Generation Transmission, in Warren, OR.

  When we (Herb & Sheri) moved the business to the Lee's Transmission building in Kelso, WA opening on Lee's birthday in April of 2012, the name was changed to Thomas Automatic Transmissions to encompass the family name of all that had come before and strengthen the ties to all of our family's customers both in Columbia and Cowlitz counties.

  Our goal is to continue the family traditions doing our best to earn your business and t help you to keep your vehicles on the road for many years to come.
