Expert Advice from Action Transmission

Winter driving in Ontario can be tough on vehicles — and your transmission feels the impact more than most drivers realize. Freezing temperatures, slush, salt, and constant cold starts all create extra strain on the system that keeps your vehicle moving. That’s why Action Transmission, a trusted local shop with decades of experience, stresses the importance of winter-specific transmission care.

If you want to protect your transmission and avoid costly repairs, here’s what the pros recommend.

1. Warm Up Your Vehicle Properly

Ontario winters can drop deep below freezing, causing transmission fluid to thicken. Thick fluid doesn’t circulate well, which can lead to delayed shifting or hard engagement.

Tip: Let your engine idle for a couple of minutes before driving. It doesn’t need a long warm-up — just enough to get the fluids moving.

2. Check Your Transmission Fluid Regularly

Cold weather can make existing transmission problems more noticeable. Low or degraded fluid is one of the leading causes of winter transmission failure.

Action Transmission recommends checking:

• Fluid level

• Fluid colour

• Signs of leaks under the vehicle

• Burning or sweet odours

If anything looks off, have it inspected before temperatures drop further.

3. Service Your Transmission Before Winter

A proper fluid change or flush (depending on your vehicle’s requirements) helps ensure smooth operation in the cold. Fresh fluid handles temperature swings far better than old, contaminated fluid.

4. Avoid Aggressive Driving on Cold Starts

Hard acceleration before the transmission warms up can stress internal components. Slippery roads also force your transmission to work harder as traction control and ABS systems activate.

Take it easy for the first few kilometres — your transmission will thank you.

5. Watch for Warning Signs

Winter can amplify symptoms that might seem minor in warmer months. Contact Action Transmission if you notice:

• Delayed or harsh shifts

• Slipping gears

• Vibration or shuddering

• Warning lights

• Unusual noises when shifting

Catching issues early can prevent a full transmission rebuild later.

6. Consider a Transmission Cooler Check

For drivers who tow, commute long distances, or drive in heavy stop-and-go traffic, a transmission cooler plays a big role in maintaining safe temperature levels. Winter may be cold, but fluctuating temperatures and heavy load conditions can still cause overheating.

Action Transmission can inspect or upgrade your cooler to keep your transmission running safely year-round.
