Any luck? I have it out now but would be good to know if there is any special procedure on installation or even removal incase it wasn't supposed to come out the way I got it out thank you
Expert:  Daniel Wilson replied 8 months ago.

I pulled up the parts breakdown. i would have removed the line on the outter cover and then the cover to access inside the actuator to disconnect it from the shaft for removal. How did you end up removing it?

Expert:  Daniel Wilson replied 8 months ago.

The lines you should be able to use and open end wrench to push in the collar into the housing to then pull out the line.

Customer: replied 8 months ago.
I tried to remove the lines using some jiffy tire line removal tools but had no luck getting the lines to release but I got the whole unit to come out by removing all the mounting bolts of unit to the case but I finally figured out that on the opposite side of the transmission the "passenger side" there is a set screw that has to be loosened that is what was holding the shaft in the transmission one removing it and getting all the shift rails back in the neutral position allowed me to remove the whole unit tried to attach pictures for you but no luck

Thanks for the update Mike. You should be perfectly fine installing the new one using the reverse procedure with new gaskets.
