Warning signs

Is it really the transmission?

Catch these early and a fluid service can save a bigger job later. If any of these sound familiar, call before it gets worse.

Slipping gears

Engine revs but the car hesitates or loses power — the classic early warning.

Hard or delayed shifts

Clunks, jerks, or a long pause going into Drive or Reverse.

Red fluid under the car

Transmission fluid is red to brown. A leak is cheap to fix now, catastrophic later.

Burning smell

Overheated fluid smells burnt — it's losing its ability to protect the internals.

Whining or grinding

New noises in gear, especially when accelerating, mean wear inside.

Check-engine light

Modern transmissions throw codes before they fail hard. We scan with factory tools.

Repair or replace?

We price both options side by side

Sometimes repair is the most cost-effective option. Other times — especially on high-mileage or heavily worn units — replacement (new, remanufactured, or quality used) makes more sense long-term. We'll price both so you can decide with real numbers.

Talk it through

Get it diagnosed first

Before you commit to a big transmission job, get an honest read on what's actually wrong.
