If a transmission for a car becomes stuck between 1st and 2nd gear the fluid should be changed. Old fluid in a transmission can cause hard shifting and stuck gears.
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.

rough shifting of gears, slipping of gears, a burning smell from the engine may be symptoms of a bad trans axle

A transmission that stumble upon acceleration between 2nd and 3rd gear may need to be flushed. Another possible cause is that the torque converter is locking when shifting between gears.
