I’m trying, without success, to find the relevant page of the service manual that shows where to fill the auto transmission with fresh fluid.
I have the early 5spd auto box. I have replaced the gearbox oil filter and oil pan gasket. But where is the filler plug?
I feel sure the JSM would show this but I don’t know how to find which of the 5069 pages is the right one.

Can anyone help please?

Can't help with the specifics of the manual. There are two basic ways to fill the 5R55N transmission.

One is via the fill plug on the aft end of the transmission, on the right side next to the driveshaft. You can see the fill plug in this thread, post #3:

You remove the plug from the center of the drain/standpipe assembly so fluid can fill to the top of the standpipe but no higher. Have a drain bucket ready to catch the overflow.


The second method is via a simple adapter that threads into the level plug on the bottom of the transmission. This video explains the process. Since you're filling via the standpipe, you basically overfill the transmission slightly and then let it drain back down to the top of the standpipe:



That video is the 5R55S transmission variant used in the Ford Explorer but the principles are the same. Poke around online for that model and you will find lots more results.

Yes those giant manuals are hard to use. Since they are in PDF form you can use the find command in PDF.
But Karl got you pointed in the right direction.

Thanks for the help guys. I managed to pump the fluid in through the upper oil cooler line. But I will recheck the level after getting her hot again. The youtube video was very illuminating. I will search for the proper fill point tomorrow as described in the other forum post.

I serviced my 5R55N a while ago and it was easy to find that service port back by the driveshaft.

Just keep in mind it is for filling only. You still have to use the standpipe (in the pan) to determine the correct level. That service port in back is just a convenient place to add fluid, but it is NOT fill to spill.

Understood 👍😉. Thank you 🙏 😀

the filler plug is above the tailshaft at the back. Sadly you really need full length ramps or a car hoist to set level (pull the level plug). I just drove around the block and pulled the level plug. I don't want to be burnt by hot oil!

DId you change the filter? I just chucked away the cork gasket that came with the filter and re-used the old rubber gasket that was already on the transmission pan.

There is a good chance that there would be no mention of anything ATF change related in the service manual, as Jaguar falsely claimed that ATF change is "for life", which is of cause nonsense to which the transmission manufacturer never subscribed. It's only "for life", if the lifetime of the Jag is defined as 10 years, or something like that...

That's my ATF change guide:

Hi Shane,
yes I replaced the filter and gasket with quality Mahle parts. I didn’t use the rubber one I had previously bought, as it was nothing like the original. I ran the engine for a while, rechecked the level and topped it up. I did that twice. But have yet to take her for a proper run and recheck.
If the oil is hot, I keep a rag handy to wipe it off my hand before it burns. My hands are quite resistant to heat (tough thick skin).

Thanks for the advice Peter, but the post you linked to is for the 6-spd ZF transmission. Mine is the early model with a 5-spd Ford gearbox, completely different. I gather the 6-spd is a much nicer box to use, but is possibly a bit more complicated, and prone to problems, if neglected.
Sometimes, I think it would be nice to have the later model S-type with six gears. But, in some ways, I like the early model; the grill, the exterior styling, and the interior are nicer, IMHO. But I prefer the later style steering wheel. But that is just my taste; not everyone would agree.
From what I see on here, the early models have less heater and gearbox problems. So that’s a bonus. But changing the plugs requires the plenum chamber/manifold to be removed and all for an extra 5 or 6 bhp. Also the breather filter cannot be replaced unless you remove one of the cylinder heads. What banana brain thought either of those situations acceptable?! I love the car though. Every time I sit in it, it feels like home.

I just added more fluid than I drained .... so when I pulled the level plug, I just let it drain until the stream of fluid draining was small and unbroken .... and figured that was good enough

I doubt a couple of hundred ml either way is going to make any difference!

Yes ignore bad advice! Thanks for the correction. They are very different transmissions for sure!

Just finished rechecking the oil level after a drive. It took a teeny bit more oil, but not much. I filled it by the proper fill point this time, until it run out of the level plug. Thank you for all the help.

You did it with the car running right? It never really seems to stop draining, I think it keeps flowing in "spurts" as the oil is pumped around. I just fugured it was close enough once the oil stream was nearly broken ....

I doubt 100% accuracy matters. It is after all a sump in the bottom of the box. What was wrong with a simple dipstick that allowed you to check the fluid from under the bonnet?

Yes, it was running. I can’t for the life of me think why they didn’t give the box a dipstick either. It’s the sort of thing they used to do. Perhaps it was to discourage DIY maintenance.

That is one thing that I dislike about modern cars; they are not made to be maintained for a prolonged lifespan. No more grease nipples or shimmed balljoints. No thought is given to ease of access for common maintenance procedures. In the ‘good ole days’ it would take ten minutes to change a radiator… Now your first ten minutes of labour is taken up removing the bumper, then much more time removing the wheel, wheel arch liner, the serpentine belt, crankshaft pulley, fan assembly, air-con condenser, air filter, intake trunking, front crossmember, under tray, etc. Whatever happened to ‘undo 4 bolts and 3 hoses to remove radiator’?

Well the dipsticks were removed for several reasons. Number one was nobody used them. Two it was another way for dirt to get into the transmission. We now can check the engine oil level without getting out of the car or getting your hands dirty and we still have people refusing to check fluid levels!

We had one guy get a new engine and then 3 weeks later burned it up because of too low oil level. Turns out he had never checked the oil after getting the car back with the rebuilt engine!

So I agree with you but they were removed for a reason.

Yes, I know what you mean about people not checking the oil. I have a friend whose car I worked on. He said he thought it might need a service as the oil light came on recently. He topped up the oil with a litre bottle.
I asked how low it was on the dipstick. He looked at me confused. He has been driving for years, but did not even know what a dipstick was, and obviously never checked his oil.
I thought, ‘His car has two dipsticks, one in the engine bay, and one in the driver’s seat.’
I demonstrated how to use the dipstick and told him to check it every week or risk a bill of thousands when the supercharged engine explodes. He was genuinely shocked that this was necessary.🤷‍♂️

I think the only reason was ..... to save money and a 50cent part. There is no way "dirt" is getting in that tiny hole!

I reckon you’re right

Yes it does. The dip stick is o-ringed sealed on some models just because of this and if left partway out will set a code.

I think this was a good one too! I do believe it.
