Automatic Transmission Servicing
We have just received the following from ZF (the
Gearbox Manufacturer for most Land Rovers from 2005)
Land Rover recommend the fluid and filter is changed
at 150,000 miles!
Here's what the manufacturer has to say!

after 50,000 to 75,000 miles to ensure optimum

are many mixed views on various forums and web pages
around Gearbox flushing, these are mostly to do with
"backward flushing" and "pulse flushing", because of
the way these systems work they can dislodge
sediments and other deposits causing damage to
internal components. At Dakar we use a
forward flush system which uses the same pressure
and direction as the Transmission system it is
connected to and therefore is a much safer way to

vehicles are notoriously hard to change the gearbox
filter which is mounted inside the brittle plastic
sump pan due to a chassis beam that runs across the
bottom of the gearbox. Here at Dakar we stock and
can fit at your discretion a Metal sump upgrade
which aids in the labour costs and is much more
robust for use in this vehicle.

"Suitable for Use (SFU) = Determined to be suitable

data such as laboratory or field testing."

"Multivehicle Synthetic ATF is a high viscosity
formulation and does not meet the viscosity profiles
of these low viscosity specifications"

gearbox flush should always be considered as a
maintenance procedure but there have been cases
where the transmission has been diagnosed as faulty
and a good gearbox service has brought the vehicle
back to a driveable state. But every vehicle is
different and we cannot say the total outcome until
the service has been carried out.

We don't recommend this as although you are only
charged for a certain amount of time, the
transmission fluid needs to be checked for level in
a certain temperature range and it can take quite a
while to cool, we do however offer a free to use

The outcome of a transmission flush is not to be
known until the procedure has been carried out. It
should only ever be seen as a Maintenance procedure.
