Hi,
That appears to be the transmission valve body cover/pan. The gasket needs to be replaced. Yes, you can do this without removing the transmission.
If you look below, I attached directions for replacing transmission switches because there are no directions only for the gasket. You will be removing the cover, cleaning things up and inspecting surfaces, and then reinstalling the cover with a new gasket.
And the fluid level will need to be checked after doing this. It can be done. The remaining directions explain the (crazy) procedure for filling and checking the level. The vehicle needs to be level when doing this, so without a lift it may be somewhat difficult.
Let me know if this helps or if you have other questions.
Take care,
joe
See pics below. Note, when checking the level, the vehicle must be flat, running, and the transmission at operating temperature.
