How Do I Know if My Transmission Needs Repair?

Transmission problems rarely fix themselves, and catching them early can be the difference between a repair and a full replacement. Some of the most common warning signs include the following:

  1. Slipping out of gear or delayed engagement when shifting
  2. Grinding, shaking, or a hard jolt when the transmission shifts
  3. Fluid leaking under the vehicle, or fluid that looks burnt or smells burnt
  4. A transmission or check engine warning light on the dashboard
  5. Whining, clunking, or humming noises that change with vehicle speed
  6. Trouble shifting into gear, or the vehicle staying stuck in one gear

If you notice any of these symptoms, don't wait. Small transmission issues can turn into expensive repairs the longer they go unaddressed.

Repair, Rebuild, or Replace: Understanding Your Options

Repair Your Transmission

Many transmission problems come down to a single worn part, a failing solenoid, or old fluid, not the wholeunit. Our technicians diagnose the actual cause first, since a full replacement isn't always necessary.

Rebuild Your Transmission:

When a transmission has significant internal wear, our shop can rebuild it in-house.

Replace with a Certified Transmission unit

For vehicles that need a full transmission replacement, we install Certified Transmission's factory-quality rebuilt transmissions. Every unit is built from the ground up with premium components and put through a rigorous multi-point inspection to meet or exceed original factory specifications, then backed by a 3-year/100,000-mile nationwide warranty.

We'll walk you through which option makes sense for your vehicle, your mileage, and your budget, no upsell, just an honest recommendation.

What's Included in a Transmission Inspection

A proper transmission inspection covers more than just checking the fluid. Our ASE-certified technicians check the full system, including the following:

  • Transmission fluid level, color, and condition
  • Filter and pan gasket
  • Seals and gaskets for leaks
  • Torque converter operation
  • Solenoids and electronic shift controls
  • Mounts and linkage
  • Road test to confirm shift quality and diagnose any slipping, hesitation, or noise

All these components need to work together for smooth, reliable shifting. If a repair, rebuild, or full replacement is needed, we'll explain exactly what's going on and what it will take to fix it.
