Nothing on the outside will tell you whats inside. You can tell by rotating the the transmission:
here's the maths
Individual gear ratio = ig
Final drive ratio = fd
Take
ig X fd = overall ratio from engine input shaft to ground.
So, for a GSR tranny lets use 1st gear:
3.23 X 4.40 = 14.212
So, with the tranny in 1st, if you rotate the input shaft 14.2 times, you end up with one full rotation of the axle.
Now an LS 1st gear:
3.23 X 4.266 = 13.77
So with the LS tranny in 1st, if you rotate the input shaft 13.77 times you end up with one full rotation of the axle.
Now how about a useful gear to tell. Lets use 4th
GSR
1.034 X 4.4 = 4.54
LS
0.966 X 4.266 = 4.12
So, if you put the tranny in 4th, rotate the input shaft 4.5 turns and get almost exactly one full rotation from the axle then you have a GSR. If it only takes LESS THAN 4.5 turns on the input shaft to get one full rotation of the axle, then you have an LS tranny.
