you will need the longer bolts found in any v8 ford equipped with 4r70 or 6r80. all six
if I leave it in drive, mine is wondering around upshifting downshifting back and forth. havent figured it out but itll have to wait now as I've grounded my car for the rest of the year to freshen my motor and wire tuck, and have found a way to use a whipple 2.9 on my 3v with a gt450 manifold, NOT THE R SPEC, and keep my 10 rib from my 2.3. gonna do some top end work , yada yada yada,,, heres a video of whats going on with the shifting. this is in drive to 95 or so , doesnt do this if I use select shift.
I don't know what I am hearing in the video but if you want to post (or send) a datalog, I am willing to look at it. Maybe we will see something that will help.
Hey, new member here, first thing I want to say is WOW, I sat down and spent a few hrs reading through all this info today. You guys have really done all the leg work for guys like me, I wanted to say thank you!
I have a question, Im going to pick up a 6r80 tmrw out of a 2012 f150 5.0 2wd. Is there any reason to choose a particular yr of 6r80 over another? Was select a shift available on all yrs? I heard the f150 6r80s have stronger clutch packs?
With a f150 6r80 in my 08 gt 3v will the 11-14 coyote driveshaft bolt right up? I know the cross member will allow me to bolt up the trans np. Also what's the best bracket option for the shift cable mounted on the f150 6r80?
Welcome to S197 forum. I will try to answer what I can.
The which year to use question has some variables. You must use a 6R80 out of a model year 2011 or newer. I am pretty sure the most up to date version of the lead frame and shift solenoids came out in 2013 (contact Baumann to confirm that this matters). Don't use a 6r80 out of any V6(I am pretty sure the bolt pattern is different than your 4.6). An F150 6R80 won't have the correct shift lever. The correct part number is in the thread and it is no big deal to change. I have also heard that the F150 6R80's come with an addition clutch in some clutch packs which would theoretically make the trans stronger. However, I wouldn't make that deciding factor on an F150 6R80 over a Mustang 6r80. If you need to make the 6r80 stronger than stock, you would be rebuilding it with different clutches from Exedy.
It doesn't matter if the donor vehicle has select a shift. Manual shifting is a function of Quick 6, not a specific year 6R80.
You will need a drive shaft, cross member and rear transmission mount from a 2011-2014 Mustang. Before you buy the F150 transmission, make sure the output flange matches the drive shaft flange (4 bolts). I believe the 2012 2WD F150 6R80 is the same over all length as the Mustang 6R80.
I don't have first hand knowledge about the shift cable bracket for the F150 transmission. I know there is an option out there and I thought it was in this thread.
@05stroker - Billy did you find a tuner?
have you tried Lund? I know he did a lot of 6r80 swaps into GT500s over the last couple of years with the Power by the Hour kits
Thanks for the reply and all the information. I did see that lever I need to purchase for the f150 transmission while reading the thread, took a screen shot of the part number for later.
My deciding factor to go with the f150 transmission over the mustang is mainly price, $400 compared to $1200 where I am. I'm glad to hear the 2011-2014 driveshaft will bolt right up for me after the transmission swap, but finding spare parts for that new of a Mustang locally is never going to happen, so I'll be paying a premium anyway. Lol
Now the lead frame and shift solenoids, I read earlier in this thread about 2013 having the newest versions. How important is this? Is it worth passing up a good deal on a low mileage 6r80 out of a 2012 f150 5.0 2wd?
Thanks again for the help.
It would be best to call Baumann (US Shift) and ask.
If you have a desire to use the transbrake feature, while you are on the phone with them, ask about the valve body mod. I was speaking to Karl Baumann (via email) about mine and he made mention of a mod to the valve body to improve the transbrake. Since I had no time to remove the valve body on my 6R80, I did not ask him for specifics. In hindsight, I wish I had asked.
This was the reply i got from USshift.
We are not aware of any significant improvements to the solenoids/leadframe.
We do not recommend any valvebody modifications, and the transbrake feature is built in to our Quick 6 pro as an all electronic feature.
please let us know if you have any other questions

I guess I'll wait and see if anyone else chimes in who may know about any difference from yr to yr, otherwise tmrw I'm gonna jump on this 2012 2wd trans, also what's the diff from the 2wd or the 4wd, they look the same same to me, one would just bolt up to the transfer case right for 4wd? Would I maybe need the 2wd flange to transfer over to the trans out of the 4x4?
I ask because the 4x4 trans is $300 locally where the 2wd is $500.. lol silly I know.
I am sorry but I can't really answer this question. The 2wd version has a tail shaft housing because a driveshaft bolts to the output shaft. The 4wd version bolts to the transfer case. On ebay, you can usually see pictures of these transmissions out of the truck. As for the output shaft, I just don't know if they are different but my guess is they are. Get the 2wd version and save yourself the grief.
Get a 6R from a 4x2 Coyote truck, I'm not sure what you were looking at but the 4x4 case is different from the 4x2 , the 4x2 case is a one piece design and has the mounting holes needed to bolt it to the cross member cast into it ...
There are no internal differences between the 2011-2014 6R80, Ford has different shift strategies for the 6R based on the flow rate of the solenoids but that doesn't affect us ..
what youre hearing is the car upshifting and then downshifting then upshifting again.
ill look for the log, dont remember where I stashed them. ive parked my car for the year to do some mods, wire tuck, custom 2.9 whipple gen3 fitment with 10 rib, etc,,, so getting another log is impossible now. if I use select shift, it works great and holds the gear and my converter is putting in the work so I know its something in the tuning
Thanks guys, I ended up going with the 2012 f150 5.0 2wd 6r80. Got the cross member, cooler, cable and shifter from a 2013 stang to. Still searching for a driveshaft.
I was talking to a guy at power by the hr performance, they have successfully completed a 6r80 install into a 02 Cobra, running the motor and trans off of a gen1 coyote pcm. Pretty interesting stuff, that would sure be a nice option.
I have not, we have it pretty good right now for cruising. I loaded the tune I built for my son's car and changed the HP settings and gear ratio. I may give him a shout though if I don't like the wot.
Do you find the shifting to be consistent at WOT? My Quick 4 shifts over a wider RPM range than I'd like at WOT, it's set to 6800rpm but it often shifts out over 7000rpm. I was thinking about changing the traction control feature to a more aggressive setting to speed up the shift reaction. One time it didn't shift until 8000rpm.
Where are you getting your tach signal from?
I used a tach adapter, can't comment much on WOT, I've only put 10 miles on my car since the swap and the kids car has yet to WOT.
I used the Autometer tach adapter, I get my data on my runs from my ProMax nitrous controller. I assume what I'm seeing is accurate, but sometimes it seems it shifts out under 6000, and on my last set of runs I had this weird RPM dip/spike on the graph so who knows to be honest.
Mine is shifting pretty close to the rpm I want it to, I did have to play around with the up-shift points and set them lower than where you you want to shift.
I want mine to shift at 7000,
1-2 up-shift set to 6650 since 1st is so short in the 6R.
2-3 up-shift 6850, 3-4 6900.
Data logs show it's up-shifting 6950-7050.
Now I just get my twins installed ...
What’s the best aftermarket shifter to go with that’s easy install into our cars? I just bought a swap and it came with a 2011 shifter but was thinking of tci or something?
