07 Sport Trac 4.0 rough idle...injector? transmission issue?

[only1bigdaddyo]

I have a 2007 Ford Explorer 4.0 with rough idle, no check engine light. We've tracked it down to fuel injector but can the rough idle cause erratic shifting with the transmission?
Thanks in advance.

ps. no codes for transmission and no check engine light.

Yes. Assuming you fixed the injector issue, disconnect the battery for about 15 minutes so the transmission computer will reset itself. Also Ford issued a TSB or two, or three, about reflashing the computer so you should check with a dealer to make sure your truck has the upgraded software.
