Wordpress. Remove automatic redirect

I use plugin Types Toolset (wp-types.com). I created a type "technic". Then I added some records: "tractor", "agrimotor", etc. So link for "tractor" look like:

my_site.com/**technic**/tractor

Now I have a problem. I need to go to the link like:

my_site.com/**not_technic**/tractor

But I can't do it. When I try to go that link, I find myself on the:
my_site.com/**technic**/tractor AGAIN.
This is redirect. I dont want it. I need to see "404 Error" OR redirect to another link, NOT my_site.com/technic/tractor. So I need remove that automatic redirect. How can I do it? I have no any idea. Please help.
