Discovery 4 TDV6 Gearbox Fluid Flush

We mostly see the earlier Discovery 3 TDV6 6 Speed models in for a gearbox mega flush so it was nice to see something a bit different when this smart Discovery 4 came to us for a preventative gearbox fluid flush. The old fluid was dark and discoloured, not the worst we have seen but certainly past it’s best.

It is a lovely looking Discovery 4, the black grille and side vents look really smart and the General Grabber AT tyres make it look mean and purposeful. The owner Michal from Autoplus Northampton let us know that he has noticed a big improvement with nice smooth gear changes like never before.

Got a Discovery 3, 4 or Range Rover Sport or Range Rover L322 with the 6 Speed Zf gearbox? It is well worth having the gearbox fluid changed at between 80-100K miles to prevent any problems. You service the engine and change the engine oil, the gearbox needs looking after too. Get in touch now or give us a call on 01536 647577 to book yours in.

      Hi Graham. The gearbox filter is incorporated into the gearbox sump. Land Rover suggest that the filter needs replacing every 150k miles. The gearbox flushing service incorporates a cleaning chemical that will flush out contaminants with the old fluid, so if the gearbox is flushed regularly and at the recommended 80-100K miles, the filter will last longer.

      We can change the filter if required, we would use the new metal type sump with separate, serviceable filter. It is an extra cost to the service and would mean the vehicle would have to be left with us for at least half a day as it is a much longer, more involved job.

      So yes, we can change the filter if the customer wants it doing as an extra cost job.
