97 v8 tranny swap to 01 HELP

[Stanleyjd]

i have a 97 5.0 awd trannys out. i got a tranny and xfer case from a 01 but the tags on the side are different. i am hesitant of putting it in cuz its good and i dont want to burn it up or possibly fry my ecu. i havent been able to locate the wiring diagram for it. the connections change and it loses the spedo sensor in the xfer case on the 01. the main harness connector is the same and the mounts of course, but the pins for communication change or i mean are different. will the computer know that and fix it? do i need a ECU from an 01 and if so how will that effect my motor its still the 97? thanks

the tranny going (01) in is Transmission Type: 4R70W, ID: PKF-BL, PN: XL2P-7000-BA

orginal is (97)Transmission Type: 4R70W , ID: PKF-AD1, PN: F67P-7000-BB

Welcome to the site, and the transfer case needs to be from a 96 or 97 because of that speed sensor. The trans is basically the same, I don't think that anything is different other than good things internally. The 2001 is a better trans than the 97, 1999 has the latest upgrades, and later models are the same inside.

Use the 2001 trans with your 97 wiring. Where do you live, I happened to buy a spare 97 trans and AWD before I learned of the differences? I now have bought a spare 99 trans for rebuilding for my 98 truck, the 98-01's are alike. If you aren't too far away, I could sell you my AWD which is the same as yours, a BW4404 transfer case. I don't need your 2001 AWD TC, but those should sell readily, I just sold my 99 BW4403. Regards,

i live in va beach va. the harness from the 97 wont work on the 01 unless i have the wiring diagram the plugs are diferent and the spedo sensor is part of the harness on the 97. for example i dont remember the name of the plug but the one near the pan on the 97 is 7 pins the 01 is nine pins for starters. then the o2 sensor that is part of is different, which is minor but still a change. what exactly do you have whats the pink tag say. i have already listed the 01 tranny and xfer case on craigs list. they guy i bought it from seems to be more expericened than my friend and i he was goign to put it in his 96 f150 with the motor which was sold seperatly wish i could have gotten that too cuz only 7k on both was sweet cuz i take you know about the gt40 head and cobra intake stock he mentioned some resource site that had the diagrams but i forgot it, but i emailed him with the info off my tranny and he seems nice enough to try to help. thanks

i think i am going to need that tranny you got. it seems your 8 hours away. freight shipping might be an option. last time i went 2 and half or so into nc to get the one i got now meeting the guy half way. let me know i am intrested still exploring options

 

[CDW6212R]

Well I am fairly certain that you can use that 2001 4R70W in your 97 truck. Basically change everything which is different, on the trans, to that from the 97 trans. That may be an odd sensor or two, but the shifter mounted sensor is the big one. The AWD transfer case though is something that you will need to have with the speed sensor.

Another member pulled apart his old AWD TC and a newer one, and swapped cases. Don't do that, just sell the 01 AWD TC and get a 96/97 like I have. You are close enough that the shipping would be under $50 for the TC. Do you really need another AWD transfer case, is it just your transmission that went out. They are separate, your original AWD TC may be fine, mine is an unknown, I was told that these had 72,000 miles on them.

As for the transmission, that 2001 model is a very good unit to have if the mileage is reasonable and it's in good shape. Let's find Chris here(Glacier), he has read a lot more than I about all Ford transmissions. He is the moderator in the trans section here. I also know of one or two other members here who have a lot of internal Ford knowledge. Let me ask Todd for one about it.

Just hold onto that 4R70W for long enough to be sure of what is needed to put it in. The trans and TC bolt together very easily, so do the trans first, then bolt up the AWD TC. Regards,

my tc is still working with its 197k miles on it its just the tranny thats out. thanks. yeah i would really like to put the 01 tranny in cuz its suspose to only have 7k in miles on its and its really clean. btw i also noticed a weight difference from the 01 to the 97 the 01 is noticibly heavier the fluids are still in it but i think think it add that much weight.

 

[CDW6212R]

Okay, with that kind of mileage you need to change the TC also. Mine wouldn't have been much help if you had only 100-120k on yours. I have 175 on my 98 truck, so I am looking forward to replacing some parts for reliability. Let me look at this 97 trans/AWD again, it's stored at a friends house outside. I'll sell the AWD TC for $150 shipped, I packed up my spare 99 model several weeks ago. It takes quite a while to get it ready to go, the thing weighs 80 pounds. This time I'll try DHL though, Fedex was $53 from here to TX.

We'll find out about the trans presently though, where's Chris?

 

[Stanleyjd]

$150 would be great. what would you want for the tranny also in the event i cant get my 01 to work?

 

[CDW6212R]

I just sent Todd a question, hopefully he or Chris will get back to us soon, it may be a day or so.

The 97 trans which I bought was from a truck with an engine fire. I got it for a fair price, but I had no plans to bolt it in. Any trans with too many miles or possible damage from a fire or hard collision should be disassembled for inspection. I can rebuild these AOD/AODE/4R70W models, but I'm really too busy at the moment. I figured that I would eventually rebuild it and sell it to someone like you. Time is just so hard to come by these days. I can do little stuff without feeling like I'm putting off important stuff too long.

Let's get that great low mileage 01 trans in your truck. If the mileage is that low then only lack of use or moisture being inside is all to worry about.

 

[Stanleyjd]

sounds good i appreciate your help

I have a wiring diagram on my website for using a 98+ 4r70w in a 96-97 Explorer. I am using a 2000 in my '96 right now.

Just splice a few wires.

Your results may vary!

That sounds interesting. Actually I received a message from my friend Todd. He mentioned the change of the later gear selector module. I agree with him that changing that gear selector may be the best answer, but we are not sure.

Has anyone else done this, has someone actually swapped the gear sensor?

Anyway, if the only answer comes down to that swapping wires around, I would suggest rewiring the connector, and not cutting any wires. Every single wiring connector in a Ford can be taken apart. The wires can be removed without damaging them, and inserted in any same knid of connector.

If the gear sensor must be used from the 2001(I don't think so), then remove all of the wires from the connector and insert them into the proper holes. Make a diagram(chart) of where the colors are to start with, and where they need to go. I can take those out and place them in other holes faster than you can splice just a few wires. Please do not cut wires, there is always a better way.

Wait for Chris to respond, he may know much more about the gear selector to say whether the 96/97 version will swap into the later trans. Regards,

 

[Stanleyjd]

section525 were you on another website before. did you take the frame and drivetrain from a 98? your truck looks familiar. never mind i just read your swap it was you. i think that site i first saw you on closed down. the site was nice i was sad to see it go.

 

[Stanleyjd]

alright i am going to hold off so you can find out if the connector can be transfered with out cutting the harness. thanks

 

[CDW6212R]

I sent Glacier another PM, now he may not be familiar with the slight differences in those connectors. I read that the earlier versions were prone to leaking in water, those were 95 car models. Things change over the years, but that gear selector should be the same internally, where it attaches to the manual shift valve.

I believe that both of my spare Explorer transmissions have the gear sensor on them. I can look at my 99 model here at home, but the 97 is at a friend's house. Let's see what Chris thinks first okay. Go ahead and make plans for the swap as needed, what ever minor thing ends up done with the trans is a fast task.

You need to get the AWD TC to be ready to start. Shall I dig out my 97 BW4404 and look it over, maybe tomorrow? regards,

 

[Stanleyjd]

yeah i got both trannys laying in my garage. i am going to use my 97 tc for the mean time till i know everything is alright. i have only driven this truck a few times. i bought it from a friend last december when the tranny went out. i guess they got tired of fixing the truck. something goes wrong about every 3 months or so. i know its leaking coolant now and i forgot about the oil leak till my friend told me he noticed a leak. i am thinking about selling it once it runs and i save up some more money. well see. thanks. i will keep you tc in mind but at the moment money is an issue.

 

[CDW6212R]

It's good, whether that engine leak is at the back or not, replace the rear engine seal. Also replace both trans seals, use Ford seals, they last longer. Regards,

Not sure if this was covered but use the DTRS from the 97 trans on the new 01, they are different signal to PCM wise.

I personally would try to use all the sensors from the 97 trans in the 01 and use the 97 wiring

 

[Stanleyjd]

yeah thats first i heard. i am not trying to rush into this, besides my friend helping me is hesitant on doing the wire splicing.

 

[410Fortune]

dont splice wires, re-pin the plugs.
Better yet you shouldnt need to splice anything if you use all the sensors from the 97 tranny in the 01, it will just plug in
