About Us

Defiance Transmission is owned and operated by Ken Shawver.  He has been doing transmission repair work since 1968 and has been running the shop since 1978  (you could say he knows a thing or two about doing transmission work!).

 Defiance Ohio Transmission Parts



Ken has had a career in drag racing for over 45 years in NHRA and IHRA Stock and Super Stock (but since retired to focus on his transmission business) .  In 2005, he was the number one qualifier at the NHRA U.S. Nationals in Indianapolis in his 1978 Pontiac Firebird Trans Am Super Stocker in a field of 186 cars.  He has had many wins throughout his racing career, but his most memorable win was in 1988 when he won the NHRA U.S. Nationals in his Olds Cutlass Stocker.  Ken had previously been a tech inspector for the IHRA crew and had also been involved in Racers for Christ.

He looks forward to hearing from you to provide the best transmission service in the Northwest Ohio, Northeast Indiana, and South Central Michigan area.  Call (419) 782-1711 or fill out the CONTACT FORM & he would be happy to answer any questions that you may have.
