There’s a kind of knowledge you don’t learn from a manual.

You pick it up from time on the bench. From taking something apart, finding the weak point, putting it back together, and doing it again until it’s right.

Ernie is one who has been around since our inception and has seen enough things broken to know that the smallest details are usually the ones that matter most.

Some of it comes from experience. Some of it comes from testing. Some of it comes from slowing down long enough to show the next guy why the little things matter.

You may not see every step, adjustment, or hard-earned lesson in a finished transmission or converter, but you can feel it in the way it performs.

Since 1989, SunCoast has been built by people who care about getting it right.

We do truck accessories too! Last week, we installed this Ranch Hand grille guard for good friend Dave G. He had a truck vs deer collision and was looking for something to protect that new bumper! A big thank you to Dave, and as a reminder, we're here for all your accessory needs, from lift kits to trailer hitches!
