welcome, I would check to see if you have brake lights this will tell you if the brake switch is working which is what releases the shift lock.The shift lock could also have come apart inside and is jamming the shift these are made of plactic and often fail.you will need to pop the cover of to see if this is what has happend. if you need further help let me know.Thanks Brian
Looks like brake lights did not come on...is brake switch something that anyone can swap out or does Volvo mechanic need too due to tricky covers location and fixing?
any independant can do the switch for you .
So far I don't think this is worth $18 bucks...is there any more expert opinion or information on this...what does independent mean? any mechanic...so I have to have towed to fix?
I have opted out so other experts can give there opinion do not respond to this post or your question will be locked to me
