    EFI does not support trans tuning on the 07.5 thru 09 Dodge trucks. They only support trans tuning in vehicles which the ECM and TCM are a combined module ('06-'07, '10+)

    I'm not promising anything ok, but given how fresh in my mind the 2010+ trans work is I will take a look again at the stand alone TCM, but no promises it will ever come to light.

    Should be a piece of cake for you. That H&S figured it out.

    Actually it has been one of the hardest (well, convoluted) things I've worked on and I've been doing this for 10+ years. H&S are smart guys they deserve credit for being the first to figure the trans out on these (I assume they were the first?)
