Ok guys! I have read 4 hours of messages regarding the shifting patterns of Ford transmissions. I have a 1997 Expedition with a 5.4 motor. I Have put the K&N Filter on it, My local exaust company installed a Flomaster single in/dual out muffler and pipes for me. After this I bought the Superchip for it. I am on my 3rd chip now. The first was great for a while. THen the perfomance went away. I could tell because I got no ping with low octane gas and the shifting went back to "lagging". The 2nd chip wouldnt allow the truck to start. The 3rd let the truck start but the shifting never changed. It still "lagged". So today, I bought the B&M electronic shifter piece. Well it works great shifting into 3rd and OD, but shifting into 2nd still laggs.

Is this a known problem????? Is there a way to eliminate this without having to open the pan up and install a shift kit?

I am open for suggestions on this guys.

Help me out!!!!!!!!

Thanks from Florida,

Stephen

Was it a "Superchip" or an ADS brand "super chip"? Just asking.

Anyway, have you tried changing the fluid? It's often a cure for various problems. Also, be sure to reset the ECU after you make any changes.
