    I am swapping a Transmission from my 2002 Lincoln LS V8 150K Miles that has a bad motor to a 2001 Lincoln LS V8 121K Miles. My question is should I replace the Torque Converter with a brand new one when I swap the transmission. I know I did not have any codes for a bad one on either of the car but wanted to know if it is a good idea to replace this. It may be a stupid question but I am in the learning process still I will admit!

    Taking it to a shop on Friday to make sure it is not a bad Transmission solenoid. I used my scanning tools and did not see that as a code but hoping that is the cause of it. Does anyone know what the code would look like if it had a bad solenoid?
    And does anyone know if there is any test's in Forscan I can do to see for sure.

    IMO due to age and use if your in there you should replace the solenoid. After learning things from my indy tranny guy, stuff just wears. Now, I only did that and valve body rebuild, wasn't anywhere near a full pull like you.

    Well if I knew for sure if the solenoid was bad I would replace that and the valve body from the other transmission I have. I just need to make sure it's not the Reverse Banding that broke and I am pretty sure this transmission is famous for that pesky band breaking.

    Well, you could drop the pan and looks for bits of metal. However, I think that a worn servo bore or a broken servo wouldn't show any metal. The OBDII codes for solenoid problems are mostly for electrical issues. There won't be any codes for mechanical problems (more common than electrical problems) for solenoid issues unless it is so bad that the transmission can't get into the correct gear.

    Yes I know if it is mechanical it will not usually throw a code, but is there a chance that a solenoid that is going bad would not throw a code?

      I am dropping the car off in the am to have the transmission checked out but here is what I can see with ForScan in the meantime

      Yeah ....that is all Greek to me ...hence you must find out if this problem is electrical or mechanical ...it is of most importance to figure out the difference and connection relating to the transmission problem...it's in your best interest to bring your car to a shop that has the right computer in order to retrieve the correct live data while car is driving and the transmission is functioning or in your case producing dysfunction

        Not true if your car is diagnosed with the proper equipment and computer it will most certainly show you a code if it's mechanically not functioning properly...the 5R55N produced evidence that was plain as day while the Mech was driving my car with the computer hooked up to it ....I went along and saw that my 2001 LS was performing a fail safe/ Limp mode default procedure and skipping over 2 gear over drive after the transmission flush another shop performed ...let me remind you the fluid was black and the transmission was on its way out long before the transmission fluid exchange but my point is it's of great importance to have the proper equipment to diagnose this complex transmission ...over drive in 2nd and 5th gear

        That not the same as throwing a DTC!
        There are several fault that the on-board diagnostics won't catch.

          And having to take it to a 2nd shop here in a few mins, cause the place I dropped it off called me back and said it won't go in reverse (Like I already didn't know that) they said it has to be rebuilt and they could not really tell me why lol... so onto the next shop! If they are gonna quote me they should at least be able to say more than it's a possible band broke lol. I know they can't see but so much without dropping the pan so it sounded more like a guessing game to me. For starters they told me it would be close to 5pm to get it looked at. I just had got back home and got a fast phone call. Did not even sound like they checked the fluid either.... So yeah onto the next shop!

          Edit: Well will have to go to the shop another day the Coolant Bottle crapped out on me today! Had to pull over fast and have it towed back home. I guess I will be replacing the cooling parts now as well.

          Unfortunately unless you take it to a shop that knows this Transmission inside and out you're going to find that mechanics aren't going to tell you shit about this transmission because most ppl don't know shit ....this is a very complex transmission ...the more I researched the less I started to know about it ....this transmission was unique and different when Ford produced it

          Yeah I actually had called one shop after the first place did not give me a honest answer, and they told me they would do all the proper test's and I got there and all they did was drive the car and say it won't go in reverse you need a rebuild. Needless to say I kinda cussed them out and told them they are liars since they did not test anything with any computers or anything. I had called one more shop and they I think would have been honest but the overheating happened so I had her towed home and will sort this stuff first and then get it checked out again. I won't have it rebuilt I will say that much I have a 2002 LS that I can take the Transmission off, same motor so it should work. I would replace the valve body and solenoid pack if I use this other transmission just to help prevent more bad stuff from happening.

            The 5R55N's were known for some problems. Issues with the valve body,,, and broken springs. If you find a reputable transmission shop,,, and the trans doesn't need a full rebuild... I would at least have a full flush done... plus a new valve body, new solenoid pack, front pump seal, rear tailshaft seal. Torque converter wouldn't hurt either.

            In all actuality... the whole problem could be the torque converter. Laugh if you want,,, call BS if you want. I've seen it happen. Old buddy of mine (decades ago), did a reverse drop in a 72 charger. I was in the car and heard a strange metallic "bang", (up by the engine), when it happened.

            He lost reverse at that point,,, and thought the trans was fubar. I told him it sounded like the torque converter, (more than once), but he wouldn't listen. He went to the boneyard and got another trans... and put it in using the old torque converter, because he didn't want to take the time to unbolt it... and because he didn't believe me.

            Guess what??? He had all the forward gears,,, but still didn't have reverse. Next time I talked to him it was fixed... after trying a second boneyard trans without luck,,, until he went back and got the torque converter from the same vehicle he got the trans from.

            I am thinking of trying something since I can't find honest shops. I am gonna drop the pan myself in the morning. Gonna check to see if any band parts broke off and if the fluid looks good I am gonna order a rebuilt valve body and solenoid, upper and lower valve body gaskets, and valve body cover, and the Filters for the transmission and a new pan gasket and a case a motorcraft mercon v and hope for the best. That car shifts so smooth I really hope I can get lucky and that is all that is wrong. Also since I have transmission cooler lines will I need XC3Z-7B155-BA?

            There is no in line filter. Although I think some people use them. Sometimes the lines will leak at the cooler after you put them back both of my LS's had worm gear clamps afterwards.

              You are supposed to add the external filter if you replace the transmission, otherwise there isn't to much point to doing it.

                Well on the Ford Parts Giant site it sure showed XC3Z-7B155-BA being a part for my car when I type in my VIN.
                I figured since I could get a OEM Filter for $13 why not just go ahead and change it. I mean rather be safe than sorry since I don't know the full history of the fluid flushes etc on this car.

                There is an internal filter/screen in the transmission. You should clean or even better replace it. 3W4Z-7A098-AA is the part number for this. (The filter that you do have.)

                The XC3Z-7B155-BA is not on your LS. It is an add on that is only used if the original transmission fails and is replaced. It's purpose is to catch any debris hiding in the transmission cooler from when the old transmission failed. In that case, it is only needed temporarily, but is usually left in place permanently.
                You can add the XC3Z-7B155-BA if you really want to, but you will be adding it, not replacing it.

                  Ok I will just hang onto that in case I have to replace the transmission. Hoping I can get lucky on the valve body swap but if not I already have a rebuilt transmission lined up for it so in that case I would use it then. Thanks for the info!

                  I just replaced with new solenoid assembly and flushed in new mercon V + filter. It solved my shift banging that I had from 2-3, 3-4. I had Lincoln do it, but they couldn't get the fluid level right after two tries so I ended up having to do it myself. Looking back I wish I had just done the entire thing myself, but I made the mistake and assumed Lincoln had techs that weren't total clowns. They ripped me off.

                  For what it is worth, I had these two codes with intermittent Check Transmission on the cluster.

                  P0798
                  P0971

                  Like I said, the shifting between gears has returned smooth, but I still have a harsh engagement into reverse. Probably need valve body work next. But that is for a future tackling as this last debacle aged me about 4 years in a month.

                  In ten years of owning my 05 LSV8 I've had four instances of XMSN trouble. First time was done by dealer under warranty (wouldn't go in reverse and upshifting hard). I believe they changed the solenoid pack. about 18 months later shifting hard, changed servos, and solenoid, I paid that 1200 dollars. About 2 years later it started having trouble in and out of 5th under torque (going up hill). Changed solenoids myself and serviced, lasted about 18 months, started same crap again. It will shift fine in manual mode, but on a grade up to speed above 42-45 it will chug or slip. When it does that, or to prevent it completely is to downshift manually to D4 and shift back up to 5th when the RPM's come up. Or just take off in D4 and only shift up to D5 if and when you need to. Last couple years I've been driving it this way (manual 4th to fifth) and don't mind it. I even tried the servos with the O ring seals on them and that didn't fix it. I still like the car. After the wife and four kids all took their turn driving it over the years I more than got my money's worth but I can't seem to get rid of it the few times it hasn't had one of the typical problems this car is famous for. After following this thread I got the itch again to maybe try replacing the XMSN with a rebuilt one and driving it a few more years. It's about the fifth car in the family and I'm retired so it sits mostly. I'd be interested to see what comes out of Dale Grib's efforts.

                    Will let you know for sure! I just have a hard time believing if a servo band broke that the reverse would be the only issue. (I know I could be wrong about that though) That transmission runs more smooth than my 2002 & 2006 LS did just has no Reverse but like I said before finding a honest transmission shop around where I live is a hard thing to do. All the parts should be here by Friday so if I have time this weekend I will be doing the repair. But I have cooling parts that I have to replace as well so will have to do that first! Otherwise would have a hard time running the car to get that transmission flushed with no degas bottle lol! All my parts are in but just dreading the effort it's gonna take to replace all of that coolant stuff.
