I have a 2001 S type 4.0 with 85K original miles. I don’t think the transmission fluid and filter have ever been changed. I would like to know how I tell which type transmission I have and the type fluid/ capacity and filter I should buy and possibly a source of supply. Thanks to all

 

You have a FORD 5R55N gearbox.

Here is the S-Type intro we were issued when this car was introduced.

Specification
Transmission weight with fluid: 90 kg (198 lbs)
Oil type: Mercon V semi-synthetic (not compatible with other fluids)
Oil capacity: 9 Litres (9.5 quarts) - new
5 Litres (5.3 quarts) - after draining

Thanks very much. So if I go with the Mercon V and just do a drain and fill and filter change will that be OK with whatever fluid is still in the tranny? Or will pulling the pan and changing the filter require the full 9.5 quarts?

I take it you are planning to do this job yourself? I'm not sure what lifting equipment you have, but the logistics can be a real pain. That's what I discovered when working on my 02's tranmission.

Draining the transmission, dropping the pan, etc. is all pretty straightforward. The difficult aspect is the car must be level for the refill procedure, but of course high enough in the air for you to crawl underneath. So unless you've got a lift in your home garage, you're looking at jackstands and ramps. On top of that, the approved jacking points are very small, especially in the rear. This doesn't leave much room to lift the car with the jack and then safely position jackstands. I found it all very frustrating and time-consuming. Depending on what you have for lifting equipment, you may find it a lot easier to simply have a shop do it while you read a magazine in the waiting room.

Details on the drain/refill procedure. Note the use of a car lift that most of us mortals don't have (yet):

If you should decide to let a shop do the procedure, one word of caution. There are two types of drain/refill services offered. The simple version is literally just draining and refilling, and is what I prefer. Some shops like to push the more involved version that uses an expensive roto-rooter vacuum/pressure machine. This thing is supposed to suck out all old fluid and clean the transmission innards at the same time. I do not recommend this type of service, as lots of old debris gets stirred up and drawn through delicate passages. I think there's just too much potential for something to cause trouble.

More details in this thread, starting at (edit) post #30. Although that thread covered a different transmission found in later cars, the basic principles for fluid service are the same:

Since this gearbox, and other variants (5R55N/S/W), have been used on popular Ford products in Europe and North America, most shops are familiar with it and the servicing procedure.

+1 on having a competent transmission shop do the servicing.

Have them also check the cooling lines for leaks and seepage.

 

Thanks for the detailed reply. Decided to let a shop here do the job cause all I have are floor jacks and only two jack stands, plus a crowded garage with bikes golf cart and other junk.

i am going to print out a lot of the procedures and be sure the guy knows the transmission type and follows the torque pattern for the pan. This is some really good information and I’m glad I asked before just jumping in. Thanks again to everyone who replied.
