What a great write up and the pictures are still there and working to this day awesome. Got a 5r55e with a Borg Warner 1356 in my 01 BoostedXPLR Sport 2dr and was thinkin to myself 5r55s swap and found this thread instantly. Although i would have to get the 4x4 5r55s and it looks like only the borg warner 4419(i think its the 4419) bolts up to it. The transfer case im thinkin of is the one that comes on the 4dr v8 explorers(either 02 to 05 or 05 to 09 or both). But theyre All Wheel Drive i think, i would prefer to have 2wd 4hi 4low. I do know their are guys that wire in a switch to disconnect the electronically controlled viscous clutch in the tcase to the front driveshaft so that it becomes 2wd instead of AWD and i could do that but i wonder what other tcase options i got with the 5r55s. Im pretty sure on either f150s or expeditions and maybe possibly explorers, ive seen 2WD,4AWD,4HI,4LOW (or maybe no 4HI), i wonder what tcase that is. Ive also seen 4x4 auto,4x4 high, 4x4 low, thats the AWD with the electronically controlled viscous clutch i think. Def gotta do some research. I could prolly make an adapter plate to mate my BW 1356 to a 4x4 5r55s which is prolly what i would prefer to do granted as long as the trans and tcase shafts are the same spline and size and long enuff to do an adapter plate. Thatd prolly be the easiest option. Unless i got a better tcase option for 2wd 4hi 4low. Im also plannin on makin a cpl cruise control buttons the shift buttons. Im gonna have a switch that when the switch is one way its cruise control and when its the other way i can shift with the cruise buttons and the trans starts shifting more for perf (raises shift pressures, changes shift points a lil, quicker shifts,etc). I was thinkin bout makin a sequential shifter in the center but naa. Itd be kool if i could put one of the newer ford column shifters on there, the ones with the shift buttons.
As far as controlling the transmission id like to try to make it work with the factory harness and PCM if possible. Although that standalone controller would be very cool and def wouldnt be a problem and im better at tuning auto transmissions then engines lol. Plus im a wiring guru lolz. The only reason im curious about hookin it into the factory harness and PCM is because i have a Livewire TS and SCT Advantage 3 software and i consider myself kind of intermediate when it comes to tuning and ive been doin it for at least a decade and have taken lots of classes. Still only slightly above a beginner. Anyways the factory trans harness would have to plug into my engine harnes or i could repin connectors to make it fit if possible of course u gotta check wiring diagrams.
But heres the real question: In the SCT Advantage 3 software in the tune file for my eaton m90 4.0 sohc with a 5r55e, under the transmission parameters it gives u an option to select wat type of transmission. Now you have to pick a number for the trans type either 0-4 or 0-5. Zero would be no transmission so the PCM would know it doesnt have to control the transmission. I think number 1 is my trans the 5r55e. I dont know what transmissions would correspond to numbers 2, 3, 4, nd mabe 5. Their is a description for trans type under trans parameters that might either describe it or maybe even say the diff trans types for each number but i dont think so, i just forget what the description says. Sct most likely wont know the diff trans types for the PCM, i dont know who would have that info, prolly some Ford EEC genius. So lets say hypothetically one of those other trans type numbers was for the 5r55s would that change any trans pins comin out of the PCM. It prolly wuld just be easier to go with the standalone unit like the guy that did this write up went with. I didnt read everything in the thread yet but i did look at all his pictures and i saw that he had to wire quite a few wires into the PCM from the trans controller. Id have to research this controller and see what leads go to what pins and what theyre functions are cuz im curious. Geez i wrote alot i didnt intend to i always do this.
