Heading into a WA summer means towing season is in full swing – boats down the coast, caravans up north, campers loaded for long weekends. But while you’re thinking about fishing, camping, and road trips, your automatic transmission is doing the heavy lifting.
Heat is the number one killer of transmissions, and when you combine warm weather with towing, that heat climbs fast. Old or contaminated transmission fluid simply can’t keep up – leading to rough shifts, overheating, and in the worst cases, transmission failure.
That’s where a professional auto transmission flush comes in. Let’s look at why it matters, what it involves, and why it’s one of the smartest pre-summer services you can book.
Why Heat and Towing Don’t Mix
Automatic transmissions rely on fluid to lubricate, cool, and transfer power. But when you’re towing in summer conditions:
- Transmission fluid heats up faster under load
- Hot ambient temperatures reduce cooling efficiency
- Old, degraded fluid loses its protective properties
The result? Slipping, burnt fluid, and potential long-term damage. And unlike engine oil changes, which most drivers are diligent with, transmission servicing is often forgotten until it’s too late.
Pro tip: It’s recommended to change transmission fluid between 50,000-100,000km depending on vehicle usage. For more severe conditions look to do it every 30,000-60,000km
What Exactly Is an Auto Transmission Flush?
Not all services are created equal. Here’s the difference:
- Drain & Fill: Removes the fluid in the pan, replaces the filter, and tops up. This usually replaces only 40–50% of the total fluid, because the rest is trapped in the torque converter and cooling lines.
- Full Transmission Flush: Uses specialised workshop equipment to cycle new fluid in while pushing old fluid out. This process replaces nearly 100% of the fluid, along with contaminants and sludge that build up over time.
Think of it as the difference between rinsing a cup and running it through a full dishwasher cycle.
Benefits of a Transmission Flush Before Summer
Booking a flush before towing season offers peace of mind and real-world benefits:
- Cooler running temps – fresh fluid transfers heat more effectively
- Smoother gear shifts – no more jolts or delays under load
- Longer transmission life – reduces wear and protects clutches
- Confidence on the road – no nasty surprises halfway to Kalbarri or Esperance

Signs It’s Time for a Transmission Service
Wondering if you’ve left it too long? Look out for:
- Slipping or jerky shifts under load
- Fluid that smells burnt or looks dark on the dipstick
- Rising transmission temps (if your vehicle has a temp gauge)
If you notice any of these, don’t wait – a flush can help prevent expensive repairs down the track.
Pre-Trip Checklist for Summer Towing
A transmission flush is only one part of smart pre-trip prep. Before you head out this summer, make sure you’ve also ticked off:
- Cooling system and radiator check
- Tyre pressures set for towing loads
- Trailer brakes and electrics tested
- Recovery Gear packed just in case
- Compressors on board to adjust tyre pressures at camp
- Solarscreens fitted to keep the cabin cool when you pull up
Wrap-Up
If you’re planning to tow a boat, caravan, or camper this summer, an automatic transmission flush is one of the cheapest forms of insurance you can buy. It keeps temps down, shifts smooth, and your transmission protected – so you can focus on the fun, not the breakdown.
