What's the problem?
Ok, i'm 16 years old and I just got my first truck, it's a 94 5.0L V8 EFI Ext. cab, and i'm having a little trouble with it. So... the deal is whenever i'm going down the highway or wherever i'm going it wont shift out of 3rd gear or go above 55 mph, if I "punch" it. If I go easy on it it does just fine. If any of you guys have any ideas on what could cause this please let me know!!!
Thanks

Make sure the truck has been driven and let it cool down for about 30 minutes.
The first thing you would need to do is drain the old transmission fluid, drop the transmission fluid pan, replace the transmission fluid filter. Remove the magnet and clean it and put back the magnet back inside the pan in the same spot. Put back the transmission fluid pan and torque the bolts to proper specs.
Never overfill the transmission fluid. Let us say your truck requires 9 quarts of transmission fluid, then put 8 1/2 quarts and measure it with the dip stick making sure it's within the safe margin. Start the engine and let it warm up and then measure the transmission level again and put little fluid at a time until the level is near the max or full level.

Our Suburban was doing the exact same thing. Turned out to be the fuel filter. OEM filter, the guy had my uncle try to blow through it - couldn't even! Now wonder the truck had to wheeze along. You try and hammer it and it would just do nothing. Maybe try that - not expensive either.
ASK THE PREVIOUS OWNER ABOUT MAINTENANCE LEVELS BEFORE YOU REDO THE FLUID. Automatic transmissions will die a swift death if the fluid happens to not have been changed in ages. The transmission gets used to the thin fluid, and when you then put in the thicker fluid it will just die. Our Suburban also had this problem. Fluid turned out to be OEM, and the mechanic that did the change neglected to tell us the fluid was nasty. This was just before a big trip - the truck didn't make it past Kansas City before it was done with.
If it is original fluid..or hasn't been changed in ages - a truck that is acting up is better then a truck sitting in the yard till you can get a rebuild.

OK. It would be my first to hear that a transmission fluid that gets used to a thin fluid would die if it's replaced with a new fresh recommended transmission fluid.
Now, the transmissions that failed in which I've heard of was that the technician put a "wrong" type of transmission fluid.
This is particularly true to some Chryslers transmissions that requires ATF +3. Some mechanics just put some Dexron III transmission fluid which has different composition than the ATF +3 and it messed up the transmissions or wear down very quickly.
I've heard of some car owners that have their transmission flushed on their older cars and it quickly deteriorated their transmission. If the transmission fluid is just flushed out without replacing the transmission filter, then it would be bad for the transmission as the filter has some debris that needs to be removed.
Probably those "old" transmissions that gets used to the thin transmission fluid are ready to die anyway and when driven on a long trip even with or without new transmission fluid would have failed anyway.
Burned smell transmission fluid can be saved with a conditioner and the right recommended transmission fluid along with the new transmission filter.
