The dreaded transmission fluid change! Not so bad if you can get the car up level. These are my notes for my own use. Information from 'official' Ford and Volvo sources. The high price of fluid from Ford will keep you guessing whether to buy 6 or 7 litres. I get FUCHS in 20 litres for the same price. Keeps well. Any corrections etc appreciated.
TRANSMISSION FLUID CHANGE Getrag 6DCT450
'POWERSHIFT'
FUCHS or PENRITE fluids are available
much cheaper than Ford. I have used FUCHS DCTF
with no problems, and is specified for the application.
You will need an ELM Obd2 adapter
and a copy of the Russian 'Forscan' software to check the temperature,
and that there are no faults in the
TCM.
Forscan is available as a paid android app and free for windows.
You will also need some way of raising the car so that it is LEVEL
at a suitable height to drain the old fluid.
FLUID CHANGE
Getrag 6DCT450 on MONDEO 2007-2014
1. PREPARATION
Ford specification WSS-M2C936A.
OR
FUCHS part number 4377
FUCHS Titan DCTF
Usually 6 litres is required, maybe a little more depending on
exactly how much drains from the fluid cooler in the process.
Transmission filter kit, comprising filter plus housing and seal.
Temperature of transmission fluid: 35-45 degrees C (Forscan)
Transmission must not be in limp mode or have DTC's.
Remove air filter housing etc to gain access to filler plug.
Raise car to a convenient height.
Note: CAR MUST BE LEVEL.
Remove undertray (10mm socket)
Place waste container to hold about 6 litres.
Remove passenger side wheel to gain access to the filter.
Remove two nuts and three screws and clamp the plastic guard
out of the way.
Engine running, brake pedal applied, select all gear positions
for 20 seconds each. Return to PARK.
2. DRAIN THE OLD FLUID
Engine off.
There are 3 drain plugs before 02/2009, 2 drain plugs after.
Remove all the 8mm hex socket drain plugs.
After the fluid has drained replace the drain plugs.
Unlock and remove the filter.
The filter housing has a plastic locking clip, a
plastic wedge is handy to hold it open.
3. FILL WITH FRESH FLUID
Prime the new filter with fluid (about 0.1 litres) and install.
Fill transmission with 5.5 litres of fluid.
Install the filler plug.
4. LEVEL ADJUSTMENT
Engine running, brake pedal applied, select all gear positions
for 20 seconds each. Return to PARK.
Remove the level check plug.
A two-foot long extension with a universal joint makes it easy.
Allow fluid to drain until it begins to drip.
Note: THE FLUID THAT ESCAPES DIRECTLY AFTER
THE FLUID LEVEL CHECK HOLE IS OPENED
IS NOT AN INDICATION OF A CORRECT FLUID LEVEL.
FLUID MUST BE ADDED THROUGH THE FILLER OPENING
WITH THE LEVEL CHECK HOLE OPEN UNTIL THE FLUID AGAIN
RUNS OUT AT THE LEVEL CHECK HOLE, AS FOLLOWS:
Top up via filler hole until fluid flows again
through the level check hole,
(be patient, takes a while to flow through)
allow to drain until it begins to drip.
Ford suggests adding fluid in 250ml lots.
No more than 750ml should be needed, depending on
how much fluid was purged from the oil cooler in the process.
Install level check and filler plugs etc.
