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.

49 years ago today, my parents took a leap of faith and opened the doors to Circle D Transmission. I had just turned 2, and my brother Chris was only a few months old. With babies in tow, they poured everything they had into building this business from the ground up.
It hasn’t always been easy—but they persevered through every challenge with grit, integrity, and heart. And because of that, this business has been a true blessing in my life. I grew up here. I met my husband here. Proof that Circle D gave me more than just a career. It gave me a life.
While my dad is no longer with us—he fought a courageous battle with ALS—and my mom is now enjoying a well-earned retirement, their legacy lives on in every vehicle we repair and every customer we serve.
We are so grateful for the trust our clients continue to place in us. Your support means everything. Here’s to 49 years of transmission excellence—and many more to come. With deep appreciation and gratitude ~Sherry ❤️ From our family to yours, thank you.
