Your transmission is one of your vehicle’s most important — and most complex — systems.
When shifting becomes rough, delayed, or unpredictable, it’s a clear sign something’s wrong.
Ignoring these symptoms can lead to major damage and expensive repairs.
At Best Choice Automotive in South Edmonton, we specialize in transmission diagnostics
and repair, not rebuilds. Our certified technicians accurately identify and repair transmission
problems early — whether it’s a slipping gear, fluid leak, or failed solenoid — so you can get
back on the road smoothly and safely.
Common Signs of Transmission Problems
Modern transmissions are electronically controlled, and even a small issue can affect
performance. Here are the most common signs you may need transmission repair or
diagnostics:
- Delayed or harsh shifting between gears
- Transmission slipping or “revving” without moving faster
- Grinding, clunking, or whining noises
- Fluid leaks under the vehicle (reddish or brown fluid)
- Check Engine or Transmission Warning Light
- Burning smell or overheating
- Vehicle stuck in one gear (limp mode)
Tip: A transmission fluid leak or slipping should never be ignored — continuing to drive with
low or contaminated fluid can cause complete transmission failure.
Our Transmission Diagnostic Process
At Best Choice Automotive, we use advanced diagnostic tools to quickly find the source of your
drivability or shifting issue. Our goal is to repair or replace faulty components, not rebuild
entire transmissions.
Our diagnostic process includes:
- Electronic system scan – reads and interprets transmission codes.
- Fluid inspection – checks condition, color, and contamination.
- Road test – replicates symptoms under load and speed conditions.
- Solenoid and pressure testing – verifies operation of internal control valves.
- Visual inspection – checks for leaks, corrosion, or damaged connectors.
Once we find the issue, we explain exactly what needs to be repaired or replaced — no surprises,
no unnecessary rebuilds.
Transmission Repairs and Services We Offer
We handle most automatic and manual transmission repairs for domestic and import vehicles.
While we don’t rebuild transmissions, we do provide full replacement options and related
services.
Our services include:
- Transmission fluid flush and filter replacement
- Transmission solenoid replacement
- Valve body service and re-sealing
Torque converter replacement - Cooler line repair or replacement
- Transmission mount replacement
- Complete transmission replacement (OEM or remanufactured units)
These services help restore smooth shifting, prevent overheating, and extend transmission life.
Transmission Fluid Service and Maintenance
Fresh, clean transmission fluid is essential to prevent wear and overheating. Over time, heat and
debris break down the fluid, reducing lubrication and hydraulic performance.
Benefits of a transmission fluid service:
- Smoother, more consistent shifting
- Extended transmission lifespan
- Improved fuel efficiency
- Reduced risk of internal wear or failure
Recommendation: Most vehicles benefit from a transmission fluid flush every
60,000–100,000 km, or sooner if used for towing or city driving in Edmonton’s stop-and-go
traffic.
Our technicians use manufacturer-approved fluid and follow OEM service intervals to protect
your transmission’s warranty and long-term performance.
Why Proper Transmission Diagnostics Matter
Because transmissions are so complex, guessing or replacing parts blindly can waste time and
money. A proper transmission diagnostic ensures only the failing component is addressed.
For example:
- A bad solenoid may cause harsh shifting — not the entire transmission.
- A cooler line leak could be the reason for slipping — not internal failure.
- A faulty sensor can trigger shifting errors without mechanical issues.
At Best Choice Automotive, our diagnostic-first approach ensures you get an accurate,
affordable solution without unnecessary rebuilds.
