04 Expedition Trans type...

I know I asked before... but can anybody tell me the difference between a 4r70 and 4r75 transmission?

Revised/upgrade front pump, converter and some minor internals but built off of the 4R70 to handle more power. Late E series with fly by wire are more processor controlled..

Have any luck finding a manual?

I'm sorry...yes atsg company has a lot of them...I bought one for my F-250 E40D trans...it's not as mystical as I thought.
Never had the confidence to do a transmission before I bought it...
