GT4 code

[95Escahoe]

So my Tahoe needs another rear end I am pretty sure it has 3.73 from when the front diff was replaced, so looked in the glovebox and see GT4 so that means I have 3.73's correct? And no g80 code so its just an open diff?

As long as it hasn't been replaced before with something else, GT4 is 3.73.

And no G80 means open diff

GU4= 3.08
GU5=3.23
GU6=3.42
GT4=3.73
GT5=4.10
G80= locking diff

Na it wasn't replaced with a different one, when the front diff was replaced went by the code and 4x4 works so it has the same gears in both, thanks for the list tho
