Automatic Gearbox Mega Flush

Does your Land Rovers gearbox need an ATF flush?

Is your auto gearbox slow at changing gear?
Juddering, hunting between gears or over-revving?
Then your auto box could benefit from an ATF mega flush and fluid change.

Why your Land Rover may need a Gearbox Mega Fluid Flush

The biggest enemy of an automatic transmission is the heat generated by the constant friction of clutch plates. Transmission fluid that is changed regularly; helps disperse heat better, lubricates clutch plates, and contains fresh detergents to keep the transmission clean and operating properly.

If the fluid is not changed, over time important additives oxidize and break down, reducing the ability of the fluid to lubricate and protect. This may cause acid, rust and sludge in the fluid, which is the leading cause of transmission failure.

A conventional transmission service leaves about 60% of the old fluid still in the system in the torque converter and oil cooler, this can cause malfunction of the transmission or complete failure.

Discovery 3's, Discovery 4's and Range Rover Sports with the ZF-6HP automatic gearbox should have a lovely smooth gear change. Land Rover state that their gearboxes are supposed to be sealed for life so no service schedule includes changing the gearbox fluid.

What exactly does lifetime mean? Do you want to extend the lifetime of your transmission?

We all know that even with the best specifications oils degrade, the gearbox fluid in these gearboxes can get hot and generally worn out!

When will my Land Rover need a gearbox flush?

Most automatic gearboxes show signs of wear around 80,000 miles, however many owners are choosing the 'preventative measure' at lower mileage before the problems start to show.

Automatic gearboxes can be expensive to repair if they have not been maintained!

Symptoms your gearbox needs a fluid change:

    1. Rough gear change during acceleration
    2. Slow or delayed gearshifts
    3. Noisy gear changes or loud transmission running noise
    4. An increase in transmission vibrations felt inside the vehicle.

    • 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

Here at JGS4X4 one of our experienced technicians will perform a full gearbox flush using the most advanced Fortron ATF technology. He will run a flushing detergent through the gearbox and exchange 100% of the total oil capacity! We use a flush additive to remove varnish and clean internal components.

"Saved me getting a new gearbox fitted as my local garage advised. Nice to meet people who are open and honest and pleased to show you how the work is being done. I would thoroughly recommend JGS4X4"

Mrs Jisholm

"Mega super! Great service from James when he carried out my mega gearbox flush on my Discovery 4 TDV6 commercial. Made a big difference to how smooth it drives. I was shocked at how dirty the old gearbox oil was for such a low mileage car. I thoroughly recommend JGS4x4."

Mark May

"My Range Rover sport had just reached 75,000 miles, I decided to have the ATF auto gearbox flush and new oil change. I must say I noticed the difference straight away, the gearbox changes up and down a lot quicker and smoother which in turn has improved the driving experience and fuel economy significantly. At a cost of £260, it's well worth it to safeguard against gearbox problems and wear in the future."
