Is your 4.0L V6 Hilux or Prado suffering from transmission whine, gear selection issues, or severe bearing wear? Restore its dependable power delivery with a premium, heavy-duty reconditioned manual transmission built specifically for the Toyota Hilux GGN25/ Toyota Prado GRJ120. At Gympie 4WD Spares, we completely strip, clean, and rebuild every unit to meet and exceed strict factory Toyota specifications.
With more than 30 years of history providing high-quality 4×4 engineering to Australian drivers, we back our expert workmanship with our 12-month / 20,000km warranty so you can tow, tour, and tackle off-road tracks with absolute confidence.
Upgraded Heavy Duty Specifications & Inclusions
- Modified 5th Gear: Engineered to prevent the common stripping and wear issues during high-speed highway cruising.
- Modified 3rd/4th Shift Hub: Restores crisp shifting dynamics and stops gear popping or selector slip.
- Modified Layshaft Thrust Washer: Upgraded to take higher load capacities, reducing internal friction and premature wear.

- Industry-Leading Component Rebuild Kits: Assembled using and recommending heavy-duty component kits.
- 100% Premium Japanese Bearings & Seals: Rebuilt exclusively with high-durability Japanese bearings and genuine seals to eliminate leaks, control tolerances, and ensure smooth shifting.
- Upgraded Core Longevity: Internal failure points—such as the notorious stripping of the 3rd/4th shift hub—are carefully addressed
- Multi-Point Bench Testing: Every gearbox passes a rigorous internal inspection by our specialist pros before leaving the workshop.
