I drove my 88 k2500 to my hunting cabin last week. It drove great all the way there, when we left a half hour later to make the hour trip home the thm700-r4 transmission would not shift out of 1st gear. I checked the fluid level, its good. I checked the shift lever at the transmission and everything was tight and moving freely. I checked the TV cable, it was a little out of adjustment but not much, I readjusted anyway.
Check the modulator and the vacuum line to it.

I have the same problem also. Hope someone has the answer.

If it has over 60000 miles it may need a transmission service, which includes a filter and fluid change, fluid may look fine but if filter is clogged and not picking up fluid fast enough when u give it gas the pump spins faster and forces fluid thru to shift, more fluid is needed to shift into higher gear.than to drive

first of all your truck is already in first gear when your going down the road....lol
SOURCE: Transmission won't shift!
Does it just not shift up to 3rd or when it shifts to 3rd it is just like neutral?

it has a problem with the second gear drum it cracks and does not fully engauge the n shifts to 3rd ..many honda owners also learn the 8 bucks a quart is the only fluid to pour in a honda..but remember 3 qaurts per drain and fill the tranny holds 7q ....it will take a case to do a drain flush...a high pressure flush will ruin a automatic tranny with alot of miles or metal deposits floating around inside..DRAIN AND FILL 3 QUARTS AT A TIME NO GASKET NEEDED ITS BUILT AND DESIGNED LIKE A MANUAL TRANNY
