The valve body for an 02 with a 5R55N is part number 7A100.
Arrggg, I can't take much more of this SST trans

can I ask were did you get that number.TheRebel said:
It did not look right to me and when I tried to plug it into my three online part number search tools, none of them new what to do with it either.
I was expecting a number like YW4Z2455BA which is the clutch pedal assembly support braket.
does anyone else have a number for the valve body.

It looked funky to me too. I got it out of a service manual. The manual prolly doesn't give the correct number to order, but you might be able to call Ford and see if they can cross it to a catalog number you can order.

Call Bill Jenkins at www.teamfordlv.com. He will be able to hook you up with a good price as well as the part number.
BTW, how do you know you need a new valve body? Sounds to me like you're just replacing parts trying to chase down a problem. A diognostic fee is much less expensive than just throwing parts at an unknown issue.

I haven't replaced anything yet, and the $198 bucks that the dealer near me wants to hold my car all day and then spend twenty minutes taking their half-assed guess is $ I could put to coils or the solenoid pack.
I'm just trying to get prices while I continue to gather information.
I would rather know that the problem is the ignition coils and just be done with it.
or I'd rather know that parts cost of repairing the sst is some XX% of the cost of parts for the Swap the MTX in project (and once it passes about 70%, I will do the swap instead).

no disrespect, but I believe you are wrong. First of all I was not talking about changing the car from an SST trans to Non-SST trans, I was talking about swapping my 2002 SST transmission for a 2002 Factory Manual Tranmission. After all it was available in the V6 cars, which is what I have.
Also while the guts of the 5r55n transmission is the same between cars the logic that is involved is not, at some level I am sure that it is this logic (or sometimes lack of) that contributes to the fraility of the SST trans.
My upset is great for these three reasons.
1. It is a problem with the very program that is supposed to protect the transmission and the remainder of the driveline. Ironic that a crude 1960's automatic with no electronic controls can protect itself and rest of the car better than the nice new modern design in this instance.
2. It is this self-preserving logic that causes more damage to the entire car then merely ignoring the driver's command or simply having better logic as to how the shift should be acomplished.
3. The fact that the processor for the transmission can be reprogrammed with a dealership level tool, but no tuner has stepped up to fix this serious gap in the cars capabilities. This is the thing that I find most annoying.
4. All the issues I have with the SST's behavior could be corrected with proper programming, which as an IT professional just makes it all the more frustrating.
I'd be more than happy to discuss what is really wrong with the design of this transmission in another thread or privately.
right now on this thread I'm trying to get all the info I can to price and diagnose the issue with my LS, so that when it completely fails or I get the kids back in school, I can do whatever I deem the best cost/risk wise

Like I did 3 or 4 years ago!! I know of at least a half dozen others that have done this. Reprogram the pcm with a sport calibration and I even have D4!
There has been talk of a manual/auto swap. There will be problems. The PCM for one. Then you have to purchase the pedal assembly. It would be less expensive to just buy a manual LS.
If you're talking V8, the Getrag can't handle the torque and won't last very long. Remember you could only get a manual Taurus SHO for quite some time because the auto couldn't handle the Yamaha's torque? Same thing here, only backwards.
Do yourself a favor and research the past threads on the pcm programming. One reason that
is because, believe it or not, every car's pcm is unique. By that I mean each pcm stores information in a different place. That's why a chip won't work and a tuner needs to know the specific calibration for each LS. The sport calibration I mentioned above isn't the pcm calibration assigned to my car. Should I go to the dealer with a calibration issue, I could be in trouble. The LS' electronic control is very sophisticated. Everything from the power windows to the radio to the transmission is connected electricly.

I understand that every pcm is different, but if Torrie can find the Trans programming in an LS calibration, then He can disable it for a manual. In fact I even emailed Torrie before and he seemed certain at the time that he could customize my PCM for non automatic operation.
as for the pedal assembly and the other hard parts, they are factory parts it is not like the LS was never designed to have any manual trans.
The Getrag will do in either car for starters. If I cannot upgrade it, there are other transmissions that can be sourced. I mean I know that in europe is possible to find a manual transmission for the xkr jag coupes, which use the 3.9(4.0 now 4.2) motor and could probably be sorted out.
It can all be done, it just depends on how badly you want it.
After some of the other swaps I have done in the past, this one is do able. The pcm is the hardest for the V6 and with Torrie involved this seems to be a non-issue.
the V8 will be much more mechanically challenging, but I pretty confident it can be done (not with the stock getrag). No scratch that it can be done, its is only a matter of time.
anyone who wants a list of the crazy swaps I have put together in the past is welcome to PM or email me.
Actually, the 3.0L SHO V6 didn't produce enough low-end torque for an ATX to function properly. That's why the ATXes all had the "stroker" 3.2L SHO; it increased the low-end torque specifically for ATX operation.LS4me said:
I have got lost reading this thread. You have a 2002 V6 with SST? Didnt think that was an option. I too had a 2002 V6 that was ridiculous with its shifting. Do you have a modified intake? Mine started acting up after i modified the airbox. Even my '05 V8 after i removed the snorkel thing off the stock airbox it immediatly acted different not to mention sounding like an old carburated 350.

Yes, I have a 2002 ls sport v6 with sst.Fla02LS said:
no, I have not modified the airbox except to add a two part washable filter.

well I tonight I picked up my wife to drive her home from work.
I pulled into the lot, and since she was going to be a few minutes I cut the engine to sit and wait.
when she came out the ls started, but was shuddering at idle. I goosed the gas and it shudder with what felt like a minor miss and then cleared out.
So I guess I really have to move on the coils soon.

nope, it did it agian tonight, even shuddering at a couple of stoplights.
I'm fairly certain that I've read about V6 owners having to have their coils replaced, but it does seem to be more prevalent in the V8s. The coils on the V8 and V6 are the same, IIRC, so there's no reason that the V6es couldn't have the same problem. I think the valve cover gasket leak that often leads to the premature death of the coils predominantly affects the pre-'03 V8s, but that's not the only thing that can kill the coils.

well according to several sources the v8 coils and the v6 coils have different numbers Motorcraft catalog lists v8- dg515 and v6 - dg517 or dg497(which no one seems to be able to confirm).
Anyway if they are the same coils then we all share the same crap.
I'm figuring that this miss will get bad enough in a couple of weeks that I'll actually have a code thrown to tell me which one is the problem. As it is now there is no code in pcm.
Odd since my mustang throws a misfire code at the drop of a hat, even when it can't tell which pair of cylinders is having the problem (4 pack coils).
I would have thought that our LS's PCMs would be more sensitive to misfires, not less
