On vehicles with a manual transmission, worn shift bushings can cause the transmission to pop out of gear, especially when coasting down in 1st or 2nd gear. Replacing all the shift linkage bushings is pretty straight forward and not expensive and will commonly correct this concern.

Shifting into 2nd is getting harder and sometime grinds, than it will pop out of 2nd&4th gear when coasting or just when you shift into those gears. No problem with 1st, 3rd, or5th
Pops out of first gear when you let off of the gas at slow speeds and some times while taking off
