I AM SO LOST!!

I have a 2002 9-5 3.0T v6 Automatic

I have the exclamation mark light on the ABS light on and the brake light on on the dash. I took it and had a diagnostic test run and it said Vehicle Speed sensor low P0502.
So I ordered a NEW genuine Saab A/T Speed Sensor Part# 95507820.

Now like the newbie I am I CANNOT for the life of me find it on the transmission.. I cannot find any guide ANYWHERE about how to install it.

And best yet I don't even know if this is the actual solution to my problem.

I intend to practically rebuild the car over time buying a little bit for the car out of each paycheck so I will eventually know the car like the back of my hand. I just need help right now with this issue.

This week I had planned to replace this speed sensor and my valve cover gasket which I realised was needing to be replaced after changing my oil with fresh Royal Purple 15w-30 full synthetic last week and a new oil filter.

Next week I may need help with installing my turbo and timing belt. they work for now but with 181k miles I feel its better to be safe now than to be sorry later.
