Went to get on freeway, truck went into passing gear. at that time it seemed to just stop pulling. Immediately the transmission began to pull again but wouldn't go into overdrive. when I stopped to inspect, I have no reverse, tran. hangs in first then seems to shift slowly into 3rd and 4th(?). could it be the shell gear housing ?
Go to online store reliable they have repair manuals I am sure you will get the solution. Here's the link

SOURCE: Transmission problems with a 2002 Chevrolet Silverado 4X4.
as you probily know this is a computer controlled trans
what we need to look at is wht the computer is looking at and what it does with the information.
so this thruck is looking at pressures in the trans and speed sensors.
also it looks at your throttle position sensor
you could have a couple of problems that wouldnt show up as a trouble code. like a bad throttle position switch .
telling your computer that you have your foot deep in the throttle calling for a down shift. but i dont like to guess on these things it should be tested .
you caould also have a programming problem with the ecm. and need to be flashed .
my first step would be to test the TPS
good luck and find me

and im so sorry for the other **** answers you recieved fixya is working on this problem
SOURCE: 2003 chevy silverado will not shift into drive or overdrive.
transmission shift solenoid is stuck open this is a common vehicle issue in automatics and not particular to any make or model vehicle 15 dollar part and arm and leg for labor if taken in
heres an idea to try
take out the transmission filter and replace with new one make sure to take not of any metal debry in trans pan this indicates the trans had sheered its gears down and a trans rebuild is needed
the transfilter needs to be changed at a certain milage interval they can get clogged up
there is a kit you buy for your truck at any parts store
its an easy change hour of time unbolt trans pan unbolt trans filter and put new one in
kit comes with new seals less than an hour you can do it yourself
to overdrive you would feel a difference in shift badley if it was that something to keep in mind
SOURCE: 88 s10 pickup truck will not shift from 3rd gear to overdrive
need more info i had a 1984 chevy half ton and first, second, and third worked fine but lock up didnt work. the problem was there was no vacum at a switch under the hood on the fire wall also your shift linkage could be out of adjustment. try driving down the road and raise up a little on the shifter.
SOURCE: slight miss in engine, hard shift from 1st to 2nd long 2nd gear
Check both O2 sensor(s) and catalytic coverter.. P0420 means catalyst below threshold. Also check the sensor at the transmission and solenoid.
SOURCE: 4l60e slips in 3rd and 4th
There are to many things that can cause this problem, best thing to is go get the ECM scanned for DTC codes at a transmission shop or Auto zone or Parts Source since they scan for free.
The ECM should have DTC code in it's memory on how the transmission is Performing and have the Transmission line tested for Fluid pressure.
Good luck and hope this helps. Oh and also ways check with more then on transmission shop if there tell you that you need a new Transmission,
It could be a simple as the transmission filter falling off causing the lost of transmission fluid pressure. Check the transmission fluid too.
