Give you a clue... http://forum.mopar1973man.com/tags.php?tag=automatic+transmission This is the tag cloud for everything automatic transmission. :rolleyes: I know that most of it listed in the 24V forums but the 47RE continued on in life of the 3rd Gens... CajFlynn is the best man for hauling with a automatic and manages to get 300K miles out of them... :thumb1:

What year are you looking at? Early 03 had 47 re and mid year 03.5 went to 48re. the 05 has a different pcm program that will not allow a reprogram to turn OD off and tow haul mode also. You get either or, they came from factory with tow haul but can get a pcm flash to make the button turn OD off instead. There are aftermarket tranny control boxes that allow it to do both so there are options if you get an 05. 06 and newer have both setings from factory just hit the button once or twice for od off and for towhaul mode.

Sad part is I'm still digging through the forum and addind tags to old post and it funny to see how many threads about automatic transmission pop up while doing the tag cloud... :rolleyes: I not say it impossible to get a good tranny but like most will tell you... You need to invest more money into the transmission to get a good life span from them. (Torque Convertor and Valve Body)

The 48 re is a good tranny, has heavier lockup clutch than 47 re had problems with. But yeah you can still improve by adding an aftermarket VB and converter. which would run around 1200-1500 for decent ones. Not much more than a quality clutch. Sad to say that Fords auto trannies behind their diesels are hands down the best out there.

So if I get a 03 or early 04 they are a little better truck? And if I get a auto make sure its a 48re and install valve body and torqe converter? Or better just stay with manual.

Anything 03.5 and newer has a 48re and they are good trannies. The 05 just has a weird pcm program that can be dealt with by adding a tranny controller box from dtt suncoast ect so you can have both tow haul mode and OD off option. 03-04 could be reflashed so you could get both functions and 06+ came from factory with both options standard. Yes they can be improved with a converter and VB like any other stock auto tranny.
