Get a filter from the dealer and get some gasket maker (high tolerance to oil and heat)
Get 3 x 4litres of DIA Queen SP III
Do the work on a windless day or inside garage as you do NOT want any dust or fluffy stuff getting into the tranny.
This what the old filter looked like with the brown old fluid
remove the end of the pipe closest to you and aim it down into a bucket (crouch in front of the vehicle and look left and down) - it may be necessary to remove a bash plate in some cases.
get a helper to start the car with the handbrake on, wheels bricked and the transmission in neutral while you aim that pipe into the bucket.
Tell him to kill the car as soon as the flow stops.
support the transmission with a jack under the dynamic damper (or close to where the rear driveshaft bolts to the transfer case)
Remove the bash plate (6x 12mm bolts)
Use a 17 spanner and crack loose the transmission pan drain plug. Drain all the oil.
Using 14 spanner, socket and medium extension undo the crossmember (6 bolts & 2 nuts in total)- some people claim to have done this job without this step but it's so easy te remove and gives great access.
I now used some engine cleaner and thoroughly cleaned around the area of the transmission pan.
Use a 10mm socket and extension and undo all the transmission pan bolts.
Very very VERY VERY carefully use a soft wedge and drive it in to remove the pan from the transmission.
Take NOTE not to lose the o-ring that seals the dipstick tube.
NOTE : The transmission is made of extremely soft aluminium
clean your tools and and hands before remove the 2 bolts holding the tranny filter in. A bit of wiggling will now give it up free of the tranny.
use some new oil and lube up the o-ring on the new filter and bolt it in - DO NOT over tighten the aluminium is EXTREMELY soft - the repair manual specifies something like 11NM.
Clean the pan extremely well and use the oppurtunity to clean the magnets in the pan - if you haven't got any, now is the time to get some. If yours has magnets and there is excessive fillings on the magnets it may be worth taking a macro picture with reference (ruler will do great) and show to tranny specialist for advice on impending danger.
clean both gasket surfaces but be carefull not to scratch or damage. Make sure it is completely oil and grease free before laying your gasket maker as prescribed and offering it up to the mating surface. A helper that can get a few bolts started is useful here. Take note of the dipstick funnel and make sure the o-ring seats nicely - prelube with oil helps a lot.
I only tightened softly with fingers and allowed a few minutes before I tightened tighter by hand screwdriver with 10mm socket attached. I then waited 60 minutes and gave a final small turn with a small socket and ratchet.
AGAIN BE CAREFUL : The manual specifies 11NM torque as the aluminium is extremely soft.
I allowed overnight to dry as I wanted to make sure it sets correctly.
Put the pan drain bolt back if you haven't done so already.
Fill with about 6 litres of fluid through the dipstick with a funnel.
Start the car in neutral again while holding the hose at the front of the car aimed at a bucket. Don't be alarmed if no fluid comes out immediately. A bright backdrop will help look at the colour of the oil.
As soon as you can see reasonable coloured red fluid come through yell at the driver to kill the engine.
connect the pipe back up again and fill the tranny bit by bit through the funnel. check the dipstick often. As soon as the level shows on the dipstick, start the car for 20 seconds in neutral and check again. Fill up to between the cold and hot mark.
Bolt the crossmember back again. I bolted the centre bits first and then used the jack to get the outside ones in.
remove the supporting jack.
Go for a very short drive, check for leaks and check the level again
NOTE : The level must be checked while car is parked on level surface. It must be idling and the box in neutral.
- move the lever through the different places while pausing at each to get the oil flowing through all the areas and get the air out.
If you are happy with the level and that there are no leaks go for a longer drive and come back. If the gearbox feels hot underneath check that the dipstick level now shows at the hot mark (manual states 70-80 degrees celsius).
keep checking the level for the next few days and any signs of leakage. Replace bash plates when you feel you are happy with the job and no leaks are showing.
The whole thing is not too difficult but a bit of a faff. If you work slow, systematic and organised it's not too bad.

Re: Gen3 : DIY - Auto Transmission fluid change
Thanks a lot. My Paj is still relatively new, 2006 model with 80k kms. I once drove through water about 0,5m deep and the clutch started to slip. It stpped after a while. I took the Paj back to the dealer and they checked, said everything was fine. Any comments?

Re: Gen3 : DIY - Auto Transmission fluid change
No, mine is automatic. It sounds if it was like a clutch slipping, revs go up with no speed increase!

Re: Gen3 : DIY - Auto Transmission fluid change
the computer may have gotten confused. Just inspect and | would actually recommend changing every 100'000km (60'000km if you tow regularly)

Re: Gen3 : DIY - Auto Transmission fluid change
I understand that the gearbox has a breather pipe that can take in water and that one should extend this breather pipe?
And thanks for all your quick replies, much appreciated.

Re: Gen3 : DIY - Auto Transmission fluid change
yes. breather pipes are essential if you are going to ford deep water. Just look for them and extend into engine bay. Lots of info on google.

I see my manual says the car must be in park, while idling, in order to check the level. Or am I mistaken?4ePikanini wrote: NOTE : The level must be checked while car is parked on level surface. It must be idling and the box in neutral..
