Replacing transmission cooler lines and following instructions of installing retainer clip and just press in new cooler line and secure with plastic clip...
Seems simple?

cannot get lines to clip in?
using a fair amount of pressure, awkward location and big hands don't help.
Watched a couple of vids, they seem to pop in?

What am missing?
Worried to grab line with pliers and crushing it, but simply will not snap in by hand?
is there a trick?
what am i missing?

 

They can be stubborn but usually its due to not having the line straight and lined up with the fitting perfectly.

a few good wiggles while pushing in will usually do it,

I've had to pull the clip out then put the line in then install the clip on a few that I just could not get the line pushed in.
