Our Story
For over six decades, Kenn’s Transmission has been Marshalltown’s trusted name in transmission repair and maintenance. Founded in 1958 by DJ’s grandfather, this family-owned business has been passed down through generations, with DJ now fully taking the reins. Having grown up in the shop and learned from both his grandfather and father, DJ continues the tradition of expert craftsmanship, customer-first service, and unmatched technical skill.
At Kenn’s Transmission, we specialize in all things transmission. While other shops may dabble in a bit of everything, we focus solely on transmissions, making us the go-to experts in the area. Our team is highly skilled in in-house transmission rebuilds, saving customers money with our expert rebuilding process. We offer transmission fluid changes and maintenance to keep vehicles running smoothly, as well as all driveline work, including transfer cases, differentials, and U-joint replacements. Our services also include flywheel repair and replacement, electrical diagnostics to identify issues quickly and accurately, clutch replacement and repair for a smoother, more efficient ride, CVT transmission replacement for modern vehicles, and wheel bearing and CV axle shaft replacement to keep cars safe on the road.
We service both foreign and domestic vehicles and work with all extended warranty coverages to make repairs as hassle-free as possible. Plus, with our key drop service, we offer added convenience for our busy customers.
Our priority is getting you back on the road safely. Our knowledgeable team ensures that your car receives the best care possible, with quick and thorough service. Customer satisfaction is at the heart of everything we do. Not all transmission problems require a complete rebuild or replacement. Our team carefully diagnoses each issue to determine the best solution, saving you time and money. Instead of costly replacements, we offer affordable, high-quality rebuilds, using top-tier technology to make your transmission better than new.
Located just two blocks east of Hy-Vee, Kenn’s Transmission is your local transmission expert dedicated to reliable, efficient, and honest service. DJ and his team are committed to ensuring that every customer experiences straightforward communication, quality workmanship, and a seamless repair process.

Iowa Man
had this to say:
The transmission in my Lincoln MKC burned out with only 65K miles and it was outside the time frame for warranty. DJ quickly diagnosed the problem and had me back on the road in less than a week. I thought the price was fair. Very satisfied with this shop!

had this to say:
Our local mechanic recommended Kenn’s transmission to us and I’m so thankful that he did. They accepted our car quickly and explained our options to us. They explained the timeline and completed our repairs within three days. Car runs great now and the price was right! Kenn’s even answered my questions about other issues and recommended a mechanic for me to reach out to. Appreciate the honesty and professionalism. I highly recommend Kenn’s Transmission!
