An automotive additive for automatic gearboxes and CVTs that rebuilds metal surfaces and reduces friction. Drivers get quieter, smoother gear changes and greater confidence on long trips. Is XADO Automatic Gearbox Restorer the right preventative step before more serious gearbox work is needed?

⚡ At a Glance
  • Restoration Performance: Rebuilds and restores metal surfaces, reduces friction and lowers vibration
  • Best for: Owners of cars with automatic gearboxes, CVTs or Tiptronic systems seeking maintenance solutions
  • Not ideal for: Drivers needing a mechanical repair to fix severe gearbox damage

An oil additive revitalizant for automatic gearboxes and CVTs that targets worn metal parts. Formulation helps maintain operation under low fluid conditions while improving shift smoothness.


Quieter, smoother gear changes, with restorative metal treatment

Concentrated revitalizant compounds act on worn control gears and contact surfaces to rebuild and eliminate surface defects, reducing metal-to-metal friction. The result is lower vibration and reduced noise during gear engagement.

Rapid reduction of shudder and a noticeably quieter gearbox improves comfort and makes daily driving less fatiguing.

Longer transmission life, with wear protection

Protective action reduces the effects of extreme friction and heat on control gears, helping to limit further material loss and degradation. Regular treatment can slow progressive wear of critical transmission components.

Extended service life for gear components means fewer premature failures and less frequent major repairs.

Continued operation at low fluid levels, with emergency lubrication support

Formulation supports lubrication behaviour under stressed conditions and can allow a transmission to continue functioning when fluid levels are low, according to the product description. This reduces immediate risk of seizure in emergency situations.

Ability to keep a gearbox running with low fluid provides drivers with extra margin to reach a workshop safely.
