5R55S Service Help Needed
Hi Guys,
I am going to replace the valve body and solenoid packs on my 03 explorer. I found the drain plug. Where is the fill plug? Is there a written procedure on the forum I did a search and could not find one.
I am attempring to correct my TC failing to lock. Trans shifts smooth and does not slip. No TC shudder of noises either. Flashing light and poor mileage is the only indicator I am seeing.
Any help would be greatly appreciated.

Had the dealer do it. They said the converter and trans are bad. I am not buying thrir BS. They basically said they would have to replace the valve body soleniods and converter. I think the converter is fine. It has never shuddered vibrated or made any noise. I believe it is not being commended to lock up. The quote was 2900 to do the service or 3200 to replace. I am thinking it's worth a $500 dollar risk at this point.

The 5R55S is the same or very similar to the trannies in the Lincoln LS series. THis tranny is a bit of a problem tranny. there are TSBs out to correct things like harsh shifting, delayed shifting etc.
Usual repairs include valve bodies, solenoids, fluid additive and even minor rebuilds. Usually handled under warranty or customer satisfaction programs.
There is not a real fill port like we are used to. There are two that can be used. There is a plug on the side of the tail of the tranny. That is a fill port and can be filled with one of those hand fluid pumps with a long hose.
The other port is really more of a "level checker" It looks like a drain plug on the bottom of the pan but it isn't. It has a tube from the plug hole up to the level where the fluid is "full". When you fill thru the other port, and the fluid starts to dribble out of the "drain" you are full. Personally I don't care for trannies that are not easily user servicable, but I guess that is the way of things.
Not sure why your TC isn't locking. If you have a tranny flashing light you need someone to pull codes. I believe you will need a tester that has Ford specific codes.
Good Luck,
Jim Henderson

does your cruise control work.the cruise control deactivation switch out on your master cylinder if not working properly will not allow your tc to lock up because it thinks you are applying the brake.disconnect the connecter and stick a ohm meter on the 2 terminals and see if you have continuity,then have someone press on the brakes.if nothing changes replace the deactivation switsh befor doing anything with the trans.this is where i would start.

Thanks for the information. I took it out and tested the CC and it worked flawlessly. Applying brakes shut it off. Interestingly enought the o/d light did not flash. I did not get a chance to go above 60mph though. I decided to use the o/d switch to see if the tc was locking and as soon as I shut the o/d off my check trans indicator went off. I did not retest the cc after the check trans lit up.

Thanks for the link. Incidentally, I drove the car about 50 miles yesterday and no O/D light and TC locked up. I ordered a new valve body, filter and solenoid pack. Will keep you guys updated with results.

Do you know what the codes were that the dealer pulled? Lots of things can prevent the converter from locking. A bad brake switch, the TPS, coolant temp sensor, even a bad O2.
I should note that just because the TC didn't shudder or make noise doesn't mean it didn't fail. Its very common for these converters to slip and burn the clutch up. Its also common for the torque converter to slip (and burn up the clutch) because of a problem with the pump in the transmission. The pump supplies the charge to the TC to apply the clutch.
I should also note that changing valve bodies isn't the easiest thing to do. Be sure you get the checkball locations correct and torque it properly. It requires an inch/lbs torque wrench.

They did not give me the codes. I will try to call and ask for them. They said the trans needs to be overhauled. I am going to replace the parts on risk. The car has been performing flawlessly the past few days.
From what I gather the check ***** reside under the seperator plate when worm grroves face up?
Lastly, is the tc commanded to lock by solenoid (via PCM) regulating fluid pressure to it?

If I remember correctly, the check ball go under the plate. On some transmissions they are on both sides.
On the 5R55E the TC clutch is commanded by the PCM, actuated by a solenoid and applied via fluid pressure from the pump.
If the transmission is working normally now, you REALLY need to know the codes. The dealer should have listed the codes on your paperwork when you paid for the diagnostics.
