This model should work with LTspice.

Since this is a .subckt, this is what you need to do to use the model. Click the right mouse button on the component (in this case the PNP) while pressing the CTRL key down, and in the dialogue that will open, replace QP with X, and for VALUE write TIP137 or whatever the .subckt is.

The text that you showed can be saved in a file named tip137.lib, and then with a spice statement (.op button) it can get included:
.lib tip137.lib
as long as the file is placed in the c:\...\LTC\LTspiceIV\lib\sub\
or wherever your ltspice was installed.

Hope this helps.

There is a button on the toolbar, on the upper right-hand side, named ".op" or something like that. When you click on it allows you to insert a spice directive. The directive that you type in should be
.lib tip142.lib
for that component. Then you place that next to your circuit, after you press OK, since your mouse cursor will have that writing attached to it.

I wonder if I can get your advice here ikoflexer .
I have been trying to load a model for the IRF9610. I have it saved to the desktop in a text file and try to "save as" to the lib/sub folder as an all files file type with the name IRF9610.lib . When I run LTSpice I get the response "Could not open the library file IRF9610.lib" which is better than I was getting til I read your posts here. Can you give me a little more detail about how to create the file for the folder? (As all files I did try all four types of encoding listed but to no avail.)
Thanks
