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.

Testimonials

On 3/2/2025 Steve Randolph had this to say:
Got us in right away and did quality work at a fair price. Courteous, friendly, and willing to listen to you and explain what was done.

On 2/27/2025 Mark had this to say:
In the past Kenn's Transmission repaired a transmission for my Buick. They removed it rebuilt it, installed it but, they were not happy with the repair. At their own choosing, removed it again, rebuilt & installed it but, they were still not happy with it. So they removed it a 3rd time. Again, at their choosing, installed a different (same model) transmission they had on the shelf which solved the problem. This was 56K miles ago & all is well. All this was billed as if they fixed the issue at the first replacement! Another time they replaced the front hubs as the bearings had failed. Another fix was to replace the instrument panel on the dash. Recently they fixed the surging I was experiencing on my Honda Pilot, with a transmission fluid change and a flash update. All of the above repairs were completed quite quickly (exception: the Buick transmission was in & out 3 times) and their charges are reasonable. They let you know the issues prior to repair & approximate cost, assuring that you want to go ahead with the repairs. Kenn's are polite and professional. Testimonial written by Mark on this site.
