The PSD does NOT use the 4R70W. It uses the E40D/4R100.

The 4R70W is basically an electronic AOD.

Isn't the E40D a electronic AOD, I'm pretty positve when I ordered the trans it was the 4R7OW, I might be wrong about that but I got those numbers from somewhere, now I'm curoius, I'll have to go look for the purchase receipts in the box.

Nope. E40D is in no way related to the AOD/E/4R70W. It is slightly related to the C6. They are comparable from the center support down.

The 4R70W has a different set of ratios and some added parts like the intermediate stub shaft, but for all practical purposes it is an electronic AOD.

The new TorqShift is based on the E40D/4R100. It has a different gearset and uses no valves, just solenoids for the shifting.

I used to be the tranny guy at a Ford dealer.

:agree2: Interesting, I had to look it up and I'm going to tell you what you already know...your right. All these years I've been calling it that. It's a 97 1 ton, so what should those years be, 4R100? I bet being in a tranny shop at Fords kept ya very busy

The 4R100 came out in '99. It's basically the just an updated E40D. Only some very minor changes between the 2.

Yes, I stayed quite busy. Mostly FWD stuff.

i would have to say go with dodge and get a cummins diesel they are one of the oldest diesel motors around so of course they worked all the bugs out unlike the 6.0 and plus they are loud and sound cool with a ton of power with 20 mpg+:greenchainsaw:
