Fuel prices are climbing again and if you’re towing, you’re feeling it more than most.

One of the biggest things we see in modern 4WDs is unnecessary transmission slip. That slip turns into heat, higher revs and increased fuel consumption.

A lock-up controller helps your torque converter lock earlier and stay locked longer. That means:
• Lower RPM when cruising
• Less heat in the transmission
• Improved fuel efficiency when towing
• Better overall drivability

It’s not about chasing unrealistic fuel savings, it’s about making your vehicle work smarter, not harder.

If you tow a caravan, boat or trailer and want to get more out of your setup, this is definitely something worth looking into.

Send us a message or give the workshop a call to chat about your setup.

Before scan tools.
Before laptops.
Before “sealed for life.”

There was experience.

This is where it started.

Hands on the guard. Bonnet up. Listening to the sounds, not plugging into it. Diagnosing by feel. Fixing things properly. No shortcuts.

Ron Hill built this workshop on knowledge, not guesswork.
Back when transmissions were rebuilt not replaced.
Back when quality actually meant something.

Same principles today.
Different technology.
Same standards.

Built on experience.
Backed by reputation.
Still doing it properly.

Why You Need a Scan Gauge

Warning lights come on after the problem starts.

A scan gauge shows you real, live data while you’re driving especially transmission temperature.

When towing or driving in Aussie conditions, temps can climb fast… and your dash won’t tell you until its too hot.

With a scan gauge you can:
✔ See temps rising
✔ Back off before damage
✔ Catch issues early
✔ Drive with peace of mind

Prevention is key.

**Why We Always Remove the Sump**

The transmission pan tells a story.

Inside the sump we can see:
• Excess clutch material
• Fine metal particles
• Signs of overheating
• Early failure warnings

Most pans have a magnet designed to catch metal particles. We inspect this carefully. A fine amount of metallic particles is normal wear. Heavy build-up or large fragments? That’s a red flag.
Without removing the pan, you miss this critical health check.

Why the Filter Matters
The transmission filter protects the valve body and clutches by catching debris.
Over time it can:
• Restrict flow
• Reduce oil pressure
• Contribute to shudder or slipping
• Accelerate internal wear
If you don’t replace the filter, you’re leaving a restriction inside the system.

Heat Is the Enemy
In Australian conditions especially towing transmission fluid breaks down faster than most people realise.
Burnt, degraded oil loses:
• Lubrication ability
• Friction stability
• Cooling efficiency
And that’s when problems start.

A proper transmission service isn’t just about changing oil.
It’s about inspection, prevention, and longevity.
If your vehicle hasn’t had a full service in the last 40,000kms, it’s worth getting it checked.

🚨 Transmission Shudder? Don’t Ignore It. 🚨

Customer concern:
Vibration under acceleration at lower speeds.
After a full road test, we confirmed a severe torque converter shudder, noticeable around town and especially as the vehicle goes into lock-up on the motorway.

🔍 What we found:
• Transmission oil level was overfull
• Oil condition was very poor
• No transmission fault codes stored

This is a perfect example of why you can’t rely on fault codes alone. The vehicle had no warning lights, yet the drivability issue was severe.

Transmission heat and degraded oil can cause major performance issues, including torque converter shudder, clutch slip and long-term internal damage.
Transmission health comes down to:
✔ Regular transmission servicing
✔ Temperature control
✔ Early diagnosis

If you’re feeling vibrations, shuddering, or unusual behaviour under acceleration, get it checked sooner rather than later. Catching it early can be the difference between a repair or full recondition.
