Introduction to Light Vehicle Transmission Services
What Transmission Services Cover
Transmission change services encompass the replacement, upgrade, or conversion of a vehicle's transmission system. Our LB1-certified services ensure every transmission modification is compliant with Australian Design Rules and safe for road use. All work is certified with a mod plate at our Glass House Mountains workshop.
Importance of Regular Transmission Maintenance
A well-maintained transmission is essential for smooth gear changes, fuel efficiency, and the overall longevity of your vehicle's drivetrain. Regular maintenance helps prevent costly breakdowns and keeps your vehicle performing at its best.
Our Transmission Change Process
Initial Diagnostics
Every transmission change begins with a thorough diagnostic assessment of your vehicle. We evaluate the condition of the existing transmission, identify any related drivetrain issues, and confirm compatibility with the replacement unit.
Transmission Fluid Change
As part of every transmission installation, we carry out a complete fluid change using the manufacturer-recommended transmission fluid. Fresh fluid ensures proper lubrication, hydraulic pressure, and cooling from the moment the new transmission is put into service.
Installation and Testing
Once the new transmission is fitted, we conduct comprehensive testing to verify correct operation. This includes checking gear engagement, shift quality, noise levels, fluid levels, and electronic system integration. Road testing confirms reliable performance under real driving conditions.
Manual Transmission Servicing and Repair
Comprehensive Gearbox Overhaul
For vehicles with manual transmissions, we offer complete gearbox overhaul services including bearing replacement, synchromesh ring renewal, and gear inspection.
Clutch Replacement Services
Clutch wear is one of the most common issues with manual transmission vehicles. We supply and fit quality clutch kits, including friction discs, pressure plates, and release bearings.
Automatic Transmission Repair and Rebuild
Our automatic transmission services include diagnostics, repair, and full rebuilds for a wide range of conventional and modern automatic transmissions. If you also need a differential change alongside your transmission work, we can coordinate both under a single certification. If you are upgrading your transmission for towing, our towing capacity guide explains GVM, GCM, and how modifications affect your legal towing capacity.
