Like the title says, I have a 2001 Expedition, 2WD, 4.6L engine, with a 4R70W. When in Drive, the tranny slips when starting out from a dead stop. However if I put it into manual first gear, no slippage. Any suggestions on what might be going on?

I don't think that's an issue unless you are rebuilding it. 4R70Ws you don't have to disconnect the shift cable. When it clicks that's it shifting so 3 notches and you're in drive....
on my E4OD, I have to disconnect the shifter linkage when dropping the transmission pan to service (Driver's side), and although it has a "line up" mark, it is especially important to get it just right, or I have experienced a similar problem. Any chance something is lodged?
