2003 Ford F250 SD - no overdrive (or always on) when button is pushed, 1 & 2 on shifter have same gearing and only 2 shifts in all. Has no power and can very slowly increase speed over long stretch of road but will coast just fine in neutral. Origanaly thought that it had water in fuel or clogged filter.

Have the vehicle scanned for trouble codes,and diagnose any codes present.If no codes,or as an alternative,i have at work a Zoom Technologies box that allows me to monitor transmission function as being commanded by the vehicle's PCM,or manually override the vehicle,and take manual control of the transmission.It is an expensive diagnostic tool.If the trans is commanded manually,and 4th gear doesnt happen,then you're looking at electric solenoids on the valve body,or possibly damaged servos.Servos can be accessed with the trans in the vehicle,and inspected.If the servos aren't the culprit,then it is likely an internal problem.

I have that exact same truck and transmission and My Transmission did the exact same thing about a year ago and there was some kind of snap ring inside the transmission that broke. I originally thought it had to be an electirical problem because the truck shifted fine until OD or if i turned OD off. The 4r70w is a light transmission and i would suggest you have a shift kit put in and they make a heavier kit to beef it up.. Sorry its probably not the new you were looking for.

Possibl eclogged cat converter,will cause miss and sluggish trans responce.

common problem for ford. and in these vans. Same thing to the 98 I had. I am a mechanic and couldn't figure it out. Thought pin fell out but linkage moved. Brought in to tranny shop and they ended up getting used on for $800

sounds like water in gas. add gas line antifreeze. 2 bottleshould do it.
