Help with s type auto transmission 5R55N

Hello to all,
I have a 2000 s type 3.0 auto and have a problem with the transmission.
It is sometimes a little jerky changing gears and more recently seems to have been slipping out of gear whilst in drive.
Sometimes when driving it feels like the box goes into neutral as the revs increase but speed doesn't,it then seems to change gear but yesterday after a long journey I got a gearbox fault warning on the display.
About 18 months ago I changed the engine and transmission but I recall when I had to remove the torque converter I lost a little fluid which I never topped up,silly I know!
Just wondered if this could be the problem and what is the procedure for fluid top up. Many thanks.

There is a good right up for drain and refill the transmission in the S type How to Guides (the last post under transmission heading).
It is very practical for DIYers as it doesn't require the car to be on a hoist. It will also give you the idea for checking and topping up the gearbox. If this is all you want to initially attempt.
Good luck and I hope it is just low on oil.

Ok, I'm no tranny tech, but I have rebuilt exactly one, and they are all vaguely similar. The pressure control solenoid fault is likely behind the other problems. Without correct tranny fluid hydraulic pressure, clutches won't work properly - they'll slip and then you'll get the incorrect ratio problem listed. I have no idea the specs of this tranny but likely one clutch pack is slipping that only two gears are showing fault. I would do some research and find out what pressure solenoid "B" is and if it's replaceable on the outside. If you can do the work yourself you could save a big bundle. Don't drive it until its fixed or you'll toast your clutches.

I would get transmission manual and diagnose everything according to manual: solenoids, ATF pressure.

Looking in the tech manual for the 5R55N yes 2nd and 5th are both run by Press. Cont. Solenoid B for "control line pressure" so if that solenoid is stuffed, it would affect both those gears.
Maybe that's it, and while it's not a nice job replacing the solenoid pack, it's not that costly...
Just have to hope that there isn't mechanical damage to 2nd & 5th from the slipping due to low pressure...

That's actually not too bad. Much better than having to pull it. A good day's work and you're up and running. But if the fluid you drain out looks dark brown you're probably too late and clutches are shot.

I have never replaced the solenoid you mention. But I had a little look online and going by the following post it seems a simple process.
"If it's an open circuit on 2 of the solenoids then in my humble opinion it is unlikely to be the transmission, and far more likely to be the loom. Check with a genuine expert like RedVictor who owns his own transmission rebuild business.
I would look at removing the gearbox loom and pinning out the loom, while measuring resistance and checking for corrosion. This should be easy to do.
If it is the solenoid then this is also easily replaced. It's just a question of removing the oil pan & swapping out the solenoid module - which is separate from the valve body.
The hardest part of that job is setting the oil level.
I would change the transmission only if you can't get the above to work - and get it done by somebody who will guarantee the work.
See the following link, the part I am talking about is 705, and is exactly the same for the V6 & V8 S-Type and Lincoln LS models."

Our forum will have plenty of good information also. But Gavin Pearson seems to give out the information you need to replace the solenoid, and he also explains a good idea. That is: to check the gearbox loom first.
This last link is to give you an idea of the cost of the solenoid. If you need one.

I hope this helps in finding the problem and enjoy the holiday.
