Are there any lights lit on the dash ? check engine , overdrive etc..
could be just a shift solenoid ... Try draining trans fluid an replacing filter. Have to drop transmission pan .. what's the fluid look like ? a nice pink color ? does it smell burnt ? Is it full ?
SOURCE: transmission wont shift into 3 and od
Sounds as if 3rd gear is our of the transmission or it could be the shift selenoid.

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.

yes itcan or it may just be the solenoid for that overdrive. make sure fluid is maintained and no mounts are broken
SOURCE: intermitten hard shift 1-2, 2-3, flare shift into 4th
The trani is electronically controlled. without a diagnostic computer you are not going to know. It may be the speed sensors (for the trani.) but thats a guess. how long since the last trani service. Fluid level and condition can affect its perfomance. Good luck.

Sounds like the passing gear cable is out of adjustment. Get a shop manual and see what the specs are on how to adjust it properly. It is a pretty simple fix.
