Automatic Gearbox Mega Flush Flushing Service


If your auto gearbox is slow at changing gear, juddering or over revving then your auto box could benefit from an ATF flush and fluid change.

Discovery 3, 4’s and Range Rover Sport’s with the ZF-6HP automatic gearbox have a lovely smooth gear change. However these gearboxes were are supposed to be sealed for life so no service schedule includes changing the gearbox fluid.

As with any hardworking oil, the gearbox fluid in these gearboxes can get hot and generally worn out. Common signs are torque converter judder, slow and erratic gear changes and what feels like clutch slip as the engine revs but the speed does not increase.

JGS4x4 have invested in a state of the art Wynn’s Transerve machine which flushes the oil system of automatic gearboxes and changes the old, worn out ATF in a simple and effective way.

We use a flush additive to remove varnish and clean internal components. The old fluid is then removed and replaced simultaneously with ZX-6HP specification fluid. We can also add a conditioner to the new ATF fluid which helps to maintain the fluid, gearbox and seals in good condition.

It is very common for the gearboxes to start to show problems from 80,000 miles. In most cases an ATF flush will eliminate these problems with the new fluid. Many owners are choosing to have this ATF fluid service done at lower mileages as a preventative measure rather than wait until they start to get problems.

This service is carried out by appointment at our workshop near Kettering. The operation takes approx. 1 hour, you are welcome to have a drink and watch the process being carried out.

We can accommodate most automatic Land Rover models and other marques, please contact us for further info.

Please call us on 01536 647577 or email us for further information or to book an appointment.

    Hi James,
    You might remember that I called in May to have my RR L322 4.4 TDV8 mega flushed to find that it was not possible on the 8 speed gearbox. Is this still the case?
    I have noted that there is an outfit in York are advertising to do it, but charging an arm & a leg.
    Please comment

      Hi Mick

      No, it is not possible to mega flush the 8-speed gearboxes.

      We have heard that some are doing them but in reality, because these gearboxes have a thermostat that does not allow the ATF fluid to flow, you end up only changing the fluid in the cooler and pipes and not the actual gearbox.

      I am researching it, but as of yet there is no easy way of getting around the thermostat problem.
