Transmission Performance Upgrades for Towing, Touring & 4wd's
If your 4WD tows, goes off road or you simply want to maximise your automatic transmission’s longevity and reliability, tailored upgrades improve how it handles load, heat and demanding driving conditions. Our packages are built to maintain shift quality, manage temperature and extend durability, giving you a transmission that performs consistently when you need it to.
Valve Body Upgrade
Upgrading the valve body increases torque capability, improves load handling and enhances shift feel for a stronger, more reliable transmission. This refined hydraulic recalibration produces quicker, more consistent shifts and greater durability. Whether you tow, drive off road or want longer service life, it provides a more confident and dependable driving experience.
Transmission Cooling System Upgrade
Upgrading your transmission cooling system is a proactive way to prevent overheating, reduce wear and extend the lifespan of your automatic. Stable temperatures mean more consistent performance, especially when towing or driving in demanding conditions. It is a smart investment for any owner wanting improved reliability, durability and peace of mind under heavy load.
Torque Converter Lock-up Control Upgrade
A lock-up controller reduces transmission heat by reducing converter slip, the main source of temperature in an automatic transmission. By engaging the clutch earlier and holding it longer, it provides stronger engine braking, better control and lower operating temperatures. This upgrade gives you a cooler, more responsive transmission and a driving experience with improved control under load.
Transmission Remapping
Transmission remapping refines the control system to improve shift timing, gear selection and torque delivery. It reduces unnecessary gear hunting and sharpens response under varying loads. This upgrade is especially effective for vehicles running larger tyres, engine tunes or carrying heavy loads, providing smoother behaviour, better torque access and more consistent performance in demanding conditions.
Temperature Monitoring Devices
Transmission temperature monitoring gives you real time fluid data and early alerts when heat rises beyond safe limits. By allowing you to react instantly, it helps you prevent wear and heat related damage. Ideal for towing or steep inclines, it supports informed decisions and lets you adjust your driving behaviour under demanding conditions.
Transmission Sump Upgrade
A deep sump upgrade increases your transmission’s fluid capacity, giving the hydraulic system more volume for heat dissipation and contaminant absorption. This helps keep temperatures lower under load and can extend service intervals. By improving cooling efficiency and fluid stability, a deep sump supports better reliability and longer transmission life in demanding conditions.
