The shift link cable could be broken, or the 1st/2nd shift fork, inside the transmission, could be damaged.
They are the reccomended shifting points for a manual transmission. When you reach 'I', shift out of first, to second, and so on.
An automatic transmission might be slow shifting from first to second because of low transmission fluid. You might also have damaged the gears in the transmission at the area between first and second.
Several things can cause your transmission to be stuck in second gear. Broken or detached shifting linkage will cause the problem. A broken shifting for in the transmission can also cause the problem.
Be sure the trans is full with the proper lubricant.

If it a manual transmission it could be fluid level/needs changing, shifting fork/linkage or syncro issues. If it is an automatic, the fluid level/condition can affect shifting, also if the valves in the valve body are sticking. The transmission can also just need rebuilding, clutches are worn.
When the cold transmission slips when shifting in the second gear, it means that either the fluid level is not correct or the filters are faulty. When this happens, your gearbox may need extensive repair or may need replacement.
There are several things that can cause your 2005 Jeep manual transmission to shift hard between first and second gear. The most common cause is a malfunctioning shifting fork.

The first cause of the jump out from one to other gear is the loose shifter fork, which connects the shifting linkage and gears of the transmission. The second cause is loose shifting linkage itself, which connects the gear shifting knob and shifting fork. The shifting linkage and shifting fork become loose due to the rapid changing of gears from one gear to other at high speed of vehicle. The third cause is the misalignment of shifting linkage to the shifting fork.
Make sure parking brake is fully released Transmission fluid and filter may need changing If it has a manual transmission, try giving it a little gas as you release the clutch into 2nd.
Assuming it is a manual transmission, it sounds like you aren't giving it enough throttle before you are releasing the clutch. You are just experiencing engine braking while the tires are actually spinning faster than the engine rpms. Give it a bit more throttle and let the clutch out a bit slower and see what happens.
