A reputation 50 years in the making.
We’re looking for the next person to join the Circle D team.
Yes, we’re hiring a Transmission Builder / Technician... but we’re really looking for something much bigger.
We’re looking for someone with integrity. Someone who takes pride in their work, thinks critically, solves problems, and genuinely cares about the people they serve.
Building transmissions can be taught. Character can’t.
For over 50 years, we’ve earned our reputation one customer, one repair, and one transmission at a time. Now we’re looking for the right person to help us carry it forward.
If you have a strong mechanical aptitude, enjoy solving problems, and want more than just another job, we’d love to hear from you.

Classic curves, modern guts.
This 1968 Cutlass convertible is getting new life with our custom-built 4L60 transmission.
If you’re restoring a classic and want updated performance under the hood, Circle D has your back.
📸
While the exterior and interior will be very reminiscent of the original car, the underpinnings have been updated to modern technology, in an effort to increase not only drivability and performance but also safety. A few of the upgrades include:
* Sport GT chassis with 9” Ford differential
* LS3 (built to emulate an Oldsmobile engine)
* -built 4L60e transmission
* Engine and Transmission powder coated “Goldsmobile” color
* 14”, 6 piston brakes
* Electric power brake booster (Tesla)
* Coach Controls wiring system
* Air climate control
* retro gauges
* custom radiator

Please keep the Circle D family in your thoughts and prayers. Patricia was a driving force behind Circle D’s success. Even though she has been retired for the past few years, her impact, dedication, and presence have never left this place — and her absence will be deeply felt.

There will never be another like her.

Celebrate the life of Patricia Sehorn, leave a kind word or memory and get funeral service information care of Pat H. Foley & Company.
