2011 Six Speed Automatic Swap into a 2005-2009?

[MikeVistaBlue06]

I searched but found nothing on this one...

I was looking at the specs for the 6 speed automatic transmission and really like the gear ratios for it.

Has anyone done or know of someone swapping the 2011 6 speed automatic into a 2005-2009 s197?

What would I need? PCM...new driveshaft...etc.? What is the transmission model # and cost?

Gear ratios for the new 6 speed are:

1st: 3.66
2nd: 2.43
3rd: 1.69
4th: 1.32
5th: 1.00
6th: 0.65

versus 5R55S

1st: 3.22
2nd: 2.29
3rd: 1.55
4th: 1.00
5th: 0.71

What I would do with such a swap is change the rear end to a 3.55 and then drive this thing in town with OD off and have a nice tall gear for the highway.

I'd actually have lower gear ratios with the new transmission and a 3.55 rear end than I have now with the 5R55S and a 3.73 rear gear until I hit 5th gear. Example: 1st gear would be: (12.993:1) versus (12.010:1).

Thx,

Mike

I doubt anyone has looked into this since you can swap in the 6060 easier. Hopefully Tremec is also going to release the T56 Magnum for the '05-'10 mustangs like they said by the end of this year which should be able to handle a fair amount of power.

Thanks, but I don't want a manual transmission. I like my automatic!

I would think that (at least this early in the game) it would be a pain in the ass unless there is some way to write a 6 speed program for your existing PCM. I could be completely wrong, but I don't think a PCM swap would be an option because of it being two completely different engines. Probably would need a new harness for it as well. Drive shaft would probably be different. Honestly I do not know because I do not know if the transmissions are the same length or not. I assume they are not. Which also brings up the cross member. As for bell housings, they are probably the same size, and probably have the same mounting holes.

Great Question..Curious as well.

I know WarFords is doing an auto swap into his car. Not sure if it's a 6 speed or not.

D'oh! My bad for not reading your post completely.

LOL no worries. You are right, it would be easier to put in a 6 speed manual!

Like mentioned, these are electronically controlled, so I think the biggest issue would be the programming/PCM.

I am curious as well a stalled 6 speed auto would IMO be the ideal street / strip / commuter trans.

What is the transmission model # and cost

the part number for the 6 speed auto from the 2011 5.0 is
BR3Z 7000-B
i don't have any pricing info on it yet though

what i'd like to find out is whether it's possible to swap the 6 speed from the manual 5.0 over to 05-09 Mustangs (that's P/N BR3Z 7003-AE)

Figure out how to throw one of these in so I know how much of a bitch it would be to do
