You might want to try this if its got a kick down cable unhook it from throutle body and pull it out as far as you can and let it snap back, do this a few of times, sometimes a valve gets hung up inside valve body of trans. and won't let it shift. If that don't help you may have to pull pan to dislodge it if thats the problem. chk. the plug on trans. (Its a 4 wire white plug) with test light with key on to see if there is power down there one will be hot, thats for overdrive, now on top of intake in front throutle body there is a sending unit that looks like a temp. sending unit with a 2 wire plug on it that sends a signial down to that plug when engine gets to temp. to let it shift to overdrive. Maybe this will help, or give you some ideas.

Purchase a gear shift repair kit for your car. They are pretty cheap. About 20 bucs. The ball and bushings are probably worn.

YOU NEED TO TAKE YOUR TRANS OUT AND HAVE IT REBUILT, THE SYNCHROS ARE WORN OUT!!
THAT IS WHY YOU HAVE TROUBLE SHIFTING GEARS!!

The more I learn about these solenoids, the more we can say that these trans shops may have lied to us from the start in stating the need for rebuilds...
Read up on all the different easily replaceable solenoids in the trans...
And a few others...
If you don't normally get the trans service done on your truck, it will be more prone to damage...
So spend the money in preventative maintenance than to suffer from these headaches and then still spending money to have it repaired, and taken for thousands instead of just barely a $100 bucks worth of solenoids...
