Does anyone know if the 2009 F-150 3V 4.6L and 6-speed ATX are the same as those used in the 2006-2008 Explorer? If it is not, are they using that new, or newly revised, version from the F150 in the 2009 Explorer/Sport Trac too? Going by the most recent order guide for the '09 Explorer it looks like FE went up an mpg or two for the V8. A new or tweaked tranny would do that.

I ask because I would be more interested in a 2009 Explorer or Sport Trac if I knew the 6-speed tranny was different from the one in the 2006-2008 models. It had some quirks that I wouldn't be comfortable living with, like slamming into a gear while decelerating for one.

they announced it - they changed some software - nothing major.

The 2009 Explorer/Mountaineer/Sport Trac utilize the same powertrains that they had in 2008.

Makes perfect sense. But is it the same powertrain that they are using in the '09 F-150? Judging by the lack of complaints about the 6-speed tranny in the Explorer for MY08 I'm guessing they got rid of the deceleration gear bump that was present in the 2 earlier years. I doubth they would want that sort of behavior in the new F Series.

I understand the tranny was built that way and the bump was normal. But I would not want to live with it. Some have had success with the latest software flash in the '06-'07 trannies and the complaints seem to have gone away for the most part on all the forums I've seen them in.

The F150 tranny is all new ... it is different from the Explorer tranny - and the Explorer will NOT get it - there is an all new explorer to be released for 2010 or (more likely) 2011 model year (within next 16 months) - so there are not further changes planned for the current generation

of course the new explorer is the unibordy "tall taurus X" explorer .. it will not have a V8 option.

The Explorer/Mountaineer through 2007MY used the 6R60 transmission. This was either a ZF design or purchased from ZF (ZF6HP26). I have felt the 2-1 decel bump in a friends car. He had it serviced this summer and the bump seems to have gone away (probably TSB 08-4-16 (//ford.justanswer.com/uploads/kennyz1963/2008-07-08_185814_tsb08-04-16.pdf))

According to this Press Release (http://www.ford.com/about-ford/news-announcements/press-releases/press-releases-detail/pr-ford-accelerates-shift-to-28198), starting in 2008MY, Explorer/Mountainer switched to the new 6R80 transmission (although I have seen contradicting information). The 2009MY F150 also uses the 6R80.

That makes sense too. I found this (http://www.ford.com/about-ford/news-announcements/press-releases/press-releases-detail/pr-ford-accelerates-shift-to-28198) on another forum and it backs up the fact that the '08 and '09 Explorer uses the 6R80 AND so does the '09 F-150. I know you said the F-150 has an all new tranny igor, but this does not jibe with what you are saying.

Having said that, I found someone on another forum who does have an '08 V8 Explorer Sport Trac and had the bump. A TSB released in February 2008 fixed the bump for him and many others. The TSB stated that it was for 6R60 trannies produced before 11/28/2007 meaning his '08 has that tranny, and the service order verified that. So either Ford started using the 6R80 after 11/28/2007 in the V8 Explorer, according to that Ford media link above, or they began using the new software after that date. Igor says it's the latter (in not so many words ;) ) and I have no reason to doubt what he says given the conflicting info that's out there. Not to mention that all of that info is getting old and things can change.

Either way it looks like the new Explorer trannies are just fine and do not suffer from the dreaded bump from 2 to 1. I'll keep them on the short list.
