What Does A Transmission Tune Do?
A transmission tune changes the decisions your automatic gearbox makes. Every modern automatic is run by software that decides when to shift, how firmly to shift, how much pressure to apply to the clutches and when to lock the torque converter. A tune, also called transmission remapping, rewrites those decisions to suit your vehicle, your […]

Why LandCruiser 300 Series Transmissions Run Hot Under Load
A 300 Series transmission cooler upgrade is a common question from Toyota LandCruiser 300 owners who tow caravans, travel long distances, drive on sand, or run heavily loaded touring setups.

These vehicles can run hotter […]
Towing with an Automatic Transmission: What You Need to Know
Towing with an automatic transmission is normal for plenty of Australian drivers. Caravans, boats, work trailers, horse floats and campers are all regularly towed behind modern automatic vehicles. A well set up automatic can tow reliably for years, but towing places far more heat and load through the transmission than normal driving. The extra weight […]
Signs Your Automatic Transmission is Failing
Most automatic transmission failures don’t happen overnight. In most cases, the gearbox starts showing warning signs long before complete failure occurs. The problem is that early symptoms are often dismissed as “just how the car drives now” until the day the vehicle suddenly won’t shift properly or drops into limp mode on the side of […]

Sealed transmissions still require servicing – No transmission is ever sealed for life!
Nearly all transmission failures we see are due to no oil changes and badly oxidised/contaminated fluid. We believe these failures can mostly be avoided. Multiple heat cycles and clutches applying and releasing constantly degrade the fluid and eventually block filters and turn the fluid black.
