So I just drove from Marquette MI to Green Bay WI and now my truck is jerking from 1st to 2nd.. The last time this happened i ended up replacing the tranny. I can't see the exact same problem happening again maybe it was mis diagnosed? Could i possibly disconnect the battery to reset the comp.. Any Ideas?

mine has been jerking exactly like yours ever since i bought it (~4 months ago) and i havent been able to get a diagnosis either

I test drove an F-150 super-cab 4x4 with the 5.4 once, it had a hard shift from 1st to 2nd, asked the guy about it when I got back, he said it had been that way since he had the tranny rebuilt, I didn't buy it because I was nervous about that.

i had that same problem but it was one of my cars, first thing i did was change the sensor on the intake because it wasn't reading the right amount of air, and that fixed it

I have a code for bank 1 sensor 2 lean but i've always had it can't get rid of it. could this be causing the computer to mess up?

That code could be causing the computer to try and compensate for it. Bank 1 sensor 2 is normally the downstream O2 sensor in the exhaust if i'm not mistaken. bank1 designates the driver or passenger side - i don't know which though.

So i disconnected the battery to reset the comp.. light stayed off and no shifting problems the whole way home! ? so i need to figure out whats setting these codes

try it.. just disconnect the battery for 10 -15 min then hook it back up it worth a shot
