Ford Flex transmission question

[akirby]

I assume it's the same tranny as the Edge. This was posted by ZanatWork over on blueovalforums.com.

 

Can anyone here help? I assume it's the 6F50.

OK, so...I have a 2009 Ford Flex Limited AWD. It's very "limited" right now, as its transmission gave up the ghost on me a month back. As I'd just lost my job and had other chaos hit at the same basic time, my autumn was off to a less-than-great beginning.

That said, I'm still paying on the car and genuinely love it when it's working. So...once re-employed, I began searching for a replacement transmission. I have a good friend with a shop, we can do the swap...but there's a confounding issue: "early" 2009 Flexes (like mine) take a different version of the transmission than those built after 5/2009...and the later transmissions are both easier to find and much cheaper.

I don't know what the difference is, and no area Ford dealer or transmission shop can seemingly tell me. I have enough in Paypal Credit to get one of the "latter" transmissions (with some warranty, even), but not the earlier version.

HELP?!!?

Yes on the 6F50, but the rest is a bit complicated. Is his Flex FWD or AWD. Looks like only the FWDs have the early/late issue, as the AWDs are showing a production date of 05/2008-05/2010. The later FWD transmission is compatible to the one in the 2009-10 Edge 3.5 version.

Any indication of the difference between the early and later version and whether the later version would fit an early Flex?

[WWWPerfA_ZN0W]

No indication of differences. I could go down into the parts detail, usually it is either a change in clutches, or simply standardization across the board. But I do not see why a newer transmission would not work with an early MY Flex. You would have to update the solenoid strategy in the PCM, that would be the major change. Sometimes there are a few minor things like elimination of unneeded mounting points, like they do with engines. Should not affect the control of the transmission by the PCM, or significantly alter the work required to install the transmission.

 

I will look in the FSM to see if it holds any clues as to differences, and update if I find any. Also will compare parts.
