gear stick wont go past neutral into park

[hellohello123]

Just wondering if some technical people could advise

its only happened twice, but when im about to parkt the car, I am unable to go past neutral into park

its almost like its electronically locked,

I presses, depress brake, and handbreak but it doesnt help,

if I keep on trying it just seems to work,

its only happened twice, but im just worried its the start of a big problem

thanks in advnace

Don't know about this problem in mercs but had similar problem with another brand. I would check the linkages first as there may be a bit of slop or a twisted one.
