Complete Transmission Care

From routine maintenance to full rebuilds, we handle every make and model with the same attention to detail and honest pricing.

Transmission Repair

Slipping gears, harsh shifts, or warning lights — we diagnose and fix transmission problems accurately the first time, saving you from costly guesswork.

Transmission Rebuild

When repair isn't enough, we tear down, inspect, and rebuild your transmission to factory specifications — using quality parts and proven procedures.

Diagnostics & Inspection

We use advanced scan tools and hands-on testing to pinpoint exactly what's wrong — then explain it in plain language with a clear repair plan.

Fluid & Filter Service

Clean fluid is the lifeblood of your transmission. We perform complete fluid exchanges and filter replacements to prevent wear and extend service life.

CVT & Automatic Transmissions

Whether it's a traditional automatic, CVT, or specialty transmission — our technicians have the training and experience to handle it correctly.

Commercial Fleet Service

Keep your business moving. We service delivery vans, trucks, and fleet vehicles with minimal downtime and competitive commercial rates.

Built on Reputation,
Not Advertising

Sea-Tac Transmission Service has been a staple in the Kent automotive community since the early 2000s. What started as a one-bay shop run by a single technician has grown into a fully equipped transmission specialty center — but the philosophy hasn't changed.

We treat every vehicle like it's our own. That means we won't recommend a rebuild when a repair will do, and we'll tell you if your transmission issue is something a good local mechanic can handle for less. Our customers come back because they know we'll be straight with them — every time.

The Difference Is in the Details

01

Honest Assessments

We diagnose first, sell second. You'll always know exactly what's needed — and what can wait — before any work begins.

02

Quality Parts, Every Time

We use OEM or equivalent-quality parts on every job. No cut corners, no cheap substitutes that fail six months later.

03

Warranty You Can Count On

Every rebuild and repair comes with our 24-month / 24,000-mile warranty — because we stand behind the work we do.

04

Fast Turnaround

We know your car being in the shop means disruption. We work efficiently to get you back on the road as soon as possible.

05

Transparent Pricing

Written estimates before any work starts. No surprise charges, no hidden fees — just clear, fair pricing you can trust.

06

Local & Dependable

We're right here in Kent on Pacific Highway South. No chains, no call centers — just a real shop you can walk into any time.

What Our Customers Say

We let our work speak for itself — but our regulars are happy to share their experience.

Brought my truck in for a rough shifting problem that two other shops couldn't figure out. Sea-Tac Transmission had it sorted the same day. Fair price, no drama — exactly what you want from a mechanic.

M
Mike R. Kent, WA

I've been bringing all my family's vehicles here for years. They've never once tried to upsell me on something I didn't need. That kind of honesty is rare — and I appreciate it deeply.

S
Sharon T. Tacoma, WA

My CVT was slipping badly and I was bracing for a huge bill. They rebuilt it at a reasonable price and it's been perfect ever since. I recommend them to everyone I know.
