Hydrolic S80 transmission?????

[GST-RIDER 95]

I got two S80 transmissions that I want to sell on line and I want to have the most educated answers possible.
Having this in mind is this an LS or a GSR or both??????
Many people post different things so what I've picked up on is the following.
The S80 is the transmission code that pertains to the US B18 engine family.
The gear ratio determines the trim model on the vehicle it came in.
Tighter gears = GSR loose gears = LS.
Am I on track so far or am I out in the boonies.
Please correct me where I'm wrong....
I've posted this exact thread in other forums with no reply's yet....
Please needed.

all hydro usdm teg trannies will say s80. two ways to find out what engine it goes to.

1. count the teeth on the gears or:

2. or a fifth gear rpm test.
