JGS4x4 recently had a local customer bring his Discovery 4 for a gearbox flush. This Discovery 4 was fitted out with a snorkel, off-road tyres, sump and transmission guards! It was a lovely looking vehicle that the owner obviously looked after and took it off-roading regularly.
A gearbox flush has many benefits and features:
✓ Cleans and flushes the internal gearbox components.
✓ Flushes out debris and contaminants
✓ Removes over 99% of old, worn out fluid
✓ Replaces exactly the same volume of new fluid
✓ The correct ZF-6HP fluid is used
✓ Eliminates common gearbox problems
✓ Preventative measure for healthy gearboxes
