Default tranny issue...need help

My truck shifts real hard from 1st to 2ND but that's the only time and it just started doing that as soon as it got cold out. I don't want it to get worse so any help would be useful

When the truck warms up does it still do that?

That's odd when's the last time your transmission fluid has been changed and has your torque converter ever been flushed?

Make sure your fluid level is correct. Follow the manual directions to check it.
If the level is ok and your vehicle has lots of miles, try an additive from a name brand. The additive will have detergents to loosen sticking valves in the shift body.
If you feel inclined, drop the pan and change the filter and fluid. Critical to use the correct TYPE (not brand) of fluid.

Is it possible for me to flush the whole thing without any special tools?

Local shop wants $140 to drop the pan and change the fluid. Is it easy enough to do on my own? Never attempted a tranny before. (That's Transmission not "Tranny" LOL)

You can do the job but as the previous post reads: makes a mess. Get the filter kit and proper TYPE trans fluid with enough quarts for the trans without converter. And, get a funnel that reaches the dipstick tube.
Lay plenty of newspaper down or even plastic. With the vehicle "not hot" or cold, loosen all the pan screws about 3-4 turns. Place a large-wide catch basin underneath. Hold the front of the trans pan up and tap on the sides of the pan with a plastic hammer or piece of wood. You want to loosen the pan and have it pivot back to dump fluid backward into the catch basin. When it breaks loose the fluid will run out all over. (that's why it can't be hot fluid)
Remove all the screws and lower the pan. Remove the filter screws and pull it down. Install the new filter using some clean fluid on the o-ring if any. Clean the pan and reinstall with a new gasket. A bit of silver metal shavings is normal. Lots is not. Don't overtighten the pan screws...they can snap if you get crazy. A torque wrench is best. Owner's manuals often have the torque spec.
Smell your fluid and compare the color to new. Burnt fluid smell is not good. Your fluid will be much darker than the new stuff because of heat.
Add the required fluid less 1 quart into the dipstick tube. Start the engine and let it idle. Shift through the PRNDL a few times. Let it idle until warm. It will warm up faster in D than P. Check the fluid and add enough to just hit the max level mark. Overfilling is very bad as the rotating parts will churn it into foam and cause problems.
Not changing the converter fluid is not a big deal. Unlike engine oil with constant combustion contaminants, trans fluid is mainly just heated. You'll notice that trans fluid cleans your hands...because it is high in detergents...important for keeping all the valves and orifices free and clean.
Good luck!
