Is it possible my tranny is still good?

slow down dude.. don't go to adjusting bands just yet...
here is where I was going by telling him to jiggle the 8 pin:
he said slow acceleration.. it likely could be starting in second, as it will in limp mode..
he said he had to coax it to shift, which is also indicative of faulty solenoids..
I've had tranny issues w/ solenoids that never kicked a code, it's not unheard of..
OP: start your truck.. manually move your lever to first, foot off brake and go.. when you reach a comfortable speed (in first gear), manually move the lever to second- does it shift? if it does, continue to build speed, and shift it to drive.. did it?
roll to almost a stop.. start to accelerate again.. does it downshift by itself?
you said it was sitting for a year?
I'm thinking the solenoid is clogged up with tranny crap.. which doesn't mean his tranny is toast, it just means he likely needs to either pull and clear the solenoid, or replace it- and swap tranny fluid (no flush!) at the same time..

the governor pressure solenoid sips fluid through it when the tranny is pumping, it is high and dry when it isn't.. gunk in a tranny from friction material can set up in it, and disallow good flow.. there is another sensor in there (speed sensor maybe?; I never get the names straight) that suffers the same, and is directly adjacent to the governor solenoid..
anyway, that friction material is somewhat pasty.. if that truck has a good bit of that in them, and it sat for a year, there is a good chance you have effectively glued it up, as it has likely dried up..
try driving it like I said, which takes automatic shifting out of the equation (it would be even better if you could locate and disconnect the 8 pin and drive it the same way).. If it shifts when YOU move the lever, chances are your tranny is serviceable.. but your fluid, filter, and pressure solenoid/speed sensor need swapping..

ok lol, once i get out of work ill do it. and let you know back. oh also i went thru the thread and im guessing you guys miss understood one thing. When i drive the truck normally (below 2k rpm) it shifts good and just sometimes it wont go into the 3rd gear, However if i accelerate little bit more over 2k rpm it wont jump to 2nd or 3rd gear so than i gotta manually change the gears and if i accelerate really hard up to like 50mph the truck stays in 2nd gear, wont jump into 3rd and than 4th gear. Hope that kinda makes a little more sence

Ok so here are my new findings:
The trans rarely shifts back too first gear so i guess that means it stays in 2nd gear. (From a 20 Mile drive it only shifted back twice)
If i put it in 1st gear, than back to drive while being stopped, it will shift too second gear but wont shift too 3rd gear even at low rpm.
And i still cant find that 8 pin i think i need new glasses >.>

go buy a haynes manual for your truck.. it is as indispensable as a wrench when working on them.. you're going to want to seek out somebody other than me, who has a functioning gray matter housing group, and who can recall the floggin' names of those two electronic critters that sit side by side next to your valve body, which is hidden by your pan..
one is the governor pressure solenoid, and the other a floggin _____ speed sensor? errrrr... I'm just passing through right now and can't go look them up for you.. seek out someone like HeyYou, Zman, Unreg, Monte, CAPT, Aim4, VW.. someone who can remember the names..
it is an easy job.. drop pan (prepare to get washed in tranny fluid).. drop filter (replace it).. remove sensors, replace.. reverse order... fill.. an hour of work, about $200 for parts/fluid/new gasket and filter..
You gave it away when you said it was stored, and that it didn't want to go to first by itself.. it's limping.. from what your omitting, I'm guessing it isn't slipping.. that bodes well to avoid a rebuild at the present time..
if you are confident in yourself and your tools, you SHOULD adjust the bands while you're in there.. it's in the manual.. it isn't hard, but it needs to be done right..
IN THE MEANTIME: drive your truck like a manual, using the column shifter.. excess slip (starting in second) works the tranny, and gets things hot.. hot eats clutch surface.. clutch surface gone will necessitate a rebuild.. let's procrastinate on that, shall we? It won't hurt it to be driven as it is so long as you manually shift, but you could burn it up pretty quick if you try to let it do it's own thing.. so, don't..
