there is no single rear end ratio for ALL the 93 automatics, my buds 97 TA had 2.73s for god sakes, look in your glove box or on the driver's door for the RPO code sheet, its filled with 3 digit codes, find GU#
GU2 is 2.73 GU4 is 3.08 GU5 is 3.23 and if you're really lucky GU6 is 3.42 G80 is positraction rear end.
