Your transmission is the hardworking middleman between your engine and your wheels. When it's happy, you never think about it. When it's not, it has a way of getting your attention, and the sooner you listen, the more options (and money) you usually keep.
Here are the signs to watch for and what to do when you notice them.
1. Slipping gears
The engine revs up but the car doesn't speed up the way it should, or it feels like it pops out of gear. Slipping is one of the clearest signs something's wrong inside.
2. Delayed or hard shifting
A pause before the car moves when you shift into Drive or Reverse, or a clunk or jolt between gears, is worth checking out.
3. A red or brown fluid leak
Most automatic transmission fluid is red when it's fresh. A reddish puddle under the middle or front of your car usually means a leak. Low fluid is one of the fastest ways to damage a transmission.
4. A burning smell
Overheated fluid has a sharp, burnt smell. It can mean the fluid is low, old or breaking down.
5. Whining, humming or clunking noises
New noises that change with speed or happen when shifting deserve a look.
6. Shaking or shuddering
A shudder at certain speeds, kind of like rolling over rumble strips, can point to torque converter or shifting issues.
7. The check engine light or a transmission warning light
Modern transmissions are computer-controlled and store trouble codes when something's off. A scan is the quickest first step.
Not every problem means a new transmission
This is the big one. Hearing "transmission" makes a lot of drivers brace for the worst. But many issues come down to low or worn-out fluid, a leaking seal, a sensor, a solenoid, or a software or wiring problem. That's why we start with a real diagnosis instead of guessing.

Transmission FAQ
Can I keep driving with a slipping transmission? We don't recommend it. Slipping usually gets worse, and continued driving can turn a smaller repair into a much bigger one.
How often should transmission fluid be changed? It varies a lot by vehicle and how you drive. Some manufacturers list specific intervals; others call the fluid "lifetime." Towing and stop-and-go driving are harder on it. Check your owner's manual, or ask us to look at the fluid's condition.
Is a transmission fluid flush bad for an older car? It depends on the car and the fluid's condition. We'll look first and recommend the right service for your vehicle.
