I bought a used tranny, and the seller already shipped because they couldn't get ahold of me, but they are asking me what ID number my tranny is. Here is the info they sent, they say there are two different ID numbers and they are ID specific, I haven't pulled mine yet and don't know if this is a problem, they claim it will bolt up, same case, etc. but two different ID numbers for whatever reason. Can anyone shed some light on this ? Will this be an issue, I hate to bolt it up and it don't work ?!

 

Heellllpppp lol. No one, what happened to the Dealership mechanics out there ? Or anyone ? I’m at a loss of what to do hate to swap this out and it don’t work ?!

 

I tried searching Google. They are both for 4x4 F150/Expeditions. Can't find what the difference between the 1 and the 3 in the part numbers. It may just be an updated part that should be compatible. Try calling a good local transmission shop and see if they can answer the question better.

You can also try sending a PM to @Mark Kovalsky , he's the resident transmission expert.

 

I remember him, thank you !

 

That won't help. He doesn't know anything about ID numbers or 6R transmissions.

Darn Mark, any suggestions, anyone else we can ask ?

 

You're good at asking questions that I don't know the answers to. This is another one.

Maybe a Ford dealer parts counter?

 

I was thinking more the service dept, I’m thinking maybe it would just need a reflash but wondering if it could be driven to the dealer or need trailering.

 

this link mentions the date cut-offs for each...and mentions with water wading?

What the heck does water wading mean ? My truck is a 16 and the Tranny is a 17. Vehicles are almost identical. Either I’m making too much of this or it’s becoming a nightmare.

 

To make things simple, do you have the VINs for BOTH vehicles? Having that information will answer your question very quickly. If I'm not mistaken, even if both transmissions are identical, you will need to program the transmission valve body ID number to your truck in order for it to function correctly. As far as part numbers go, "FL1Z" identifies 2015 model year Expedition. And "FL3Z" identifies 2015 model year F-150 if it matters.

Hi Mike, you helped me out with a few 6.0 issues in the past hopefully you can shed some light on this. Exact vehicles one year apart the vehicle needing tranny is a 2016 Expedition vin # 1FMJK2ATXGEF19875
the donor vehicle the transmission was removed from us a 2017 Expedition vin # 1FMJK2AT8HEA82167

Do I need to have it programmed ? who can do it ? my closest dealer is an hour ride, if that’s where I have to bring it, can I drive it there ? What happens if not programmed ? Where do we get the valve body ID Number ?


Thank You in Advance !

 

Sorry for the delay in getting back to you. I needed to log into my fmcdealer website to access the information I needed to answer your questions. The good news is, with the VINs you provided for both vehicles, I come up with the same part numbers for the transmission assembly. I get FL1Z-7000-B which change up FL1Z-7000-DRM. Now that we've confirmed both transmissions are identical, onto the programming requirements to enable the donor transmission to function upon installation. What you need to do is locate the Solenoid Strategy Identification Tag located on the left side of the transmission for BOTH transmissions.

So basically there are TWO fields of digits which need to be reprogrammed. One is the solenoid body strategy (13 digits), and the other is the solenoid body identification (12 digits). The 13 digit solenoid body strategy number consists of only numbers (no letters used).

So.... what you need to use is IDS or other scan tool that is capable of retrieving this information, and reprogramming the two fields previously mentioned above to match that on the ID tag of the donor transmission in order for the donor transmission to function correctly. If you don't have access to IDS, I'm fairly certain Forscan is capable of performing this for you.

In answer to your questions regarding whether you can drive it to the dealership to have it done, and what happens if you don't have it done, the workshop manual for this vehicle in Section 307-01 states very explicitly "If the solenoid body information is not correct, transmission damage or driveability concerns can occur."

That said, I would definitely not take a chance driving it to the dealership to have it programmed. You would be better off either towing it to the dealership (I know, inconvenient and probably expensive being an hour away from you), or getting an IDS or other capable scan tool and doing it where the transmission installation is being done.

Hope this helps.

 

Thanks Mike that’s a big help !


You think it would hurt just to drive it up on a trailer if I have to bring to a dealer ? When you guys replace trannies of this year range at the dealer I’m sure you have to do the same every time so hoping any dealer can do this and I’m gonna ask a few guys I know if they have programmers that can do this.

 

Sidebar. I'm not a transmission technician. But....

BEFORE you incur the expense and inconvenience of having your truck trailered to the dealership to have the programming done, it would be a very wise idea to call the dealership to confirm that they do in fact have a transmission technician that can, and knows how to use IDS to do what you request. Ask to speak to the service manager to ask this question if necessary. The reason I say this, is because there are a lot of dealerships that don't have transmission technicians anymore. And for those dealerships that don't, more often than not, vehicles are being subletted out to dedicated transmission shops to have the work done.

It would be much more convenient, if you were able to find someone with a scan tool capable of doing this for you at the place where your transmission is being swapped in. Have you swapped the transmission already? If so, it really doesn't take long for the programming to be done. All that would be needed, is for the scan tool to be connected and navigate to the programming menu where the previously mentioned ID and strategy numbers are brought up. The numbers brought up on the screen should match the numbers on the tag of the original transmission in the previously mentioned location. And what needs to be done, is to simply enter the numbers of the donor transmission into the fields on the screen and then programmed in as instructed by the scan tool. If using IDS, it's called programmable parameters under the sub menu of transmission if I'm not mistaken.
