Allen, this is the switch you are looking for, 2 philips head screws hold it to the rear of tranny, it's near the top. I've crawled under car to get at this part in the past, very tight squeeze getting the Leatherman screwdriver in there, but I never had to raise/ lower tranny to get at it.

If I did it again, I'd use one of those short screwdrivers which have the 90 degree bend to them. A regular screwdriver (with handle) won't be able to fit in there.

I remember driving the front wheels up onto curb so front end was a bit higher off the ground, that way I had easier time getting underneath the car. Didn't have a floor jack, and didn't want to crush my chest if car came crashing down (after slipping off tire jack)
