damn shifter!!

[SVX PlayBoy]

This is getting very irritating and embarassing. Everytime I start my car, and go to shift it into reverse or drive, it won't budge out of park, or it will shift like normal. When it does stick, I have to shake it like crazy, then it will slide into the gear.

Recently, i thought the shift lock had something to do with it, so i pressed and held it, and it shifts like no problem, is their anything i can do to not have to press the shift lock button everytime?
