wait autos have 3.23's?

damn where did i get the idea mine was 2.73 from

 

Like I said before, some autos came with 2.73's, but I believe the majority came with 3.23's.

 

I spent a year looking for the right Fbody for me... I drove roughly 5 autos and every single one of them was 2.73s.. In fact, I have yet to even see a 3.23 automatic.

yea thats what i thought... im gonna go take a look at gm's website to see what they say

 

Thread about what RPO code = what gears

 

let me make this esay for you guys if you can select 1st gear on your shifter you have 3.23s if you cant and it only goes down to 2nd and it say PRND32 and no first you have 2.73s. if you have a 6 speed you got 3.42s

 

Not totally true. In 1993, the M28 gearbox received 2.73 gears, and the M29 received 3.23s.

In 1993, no M6 car was equipped with 3.42s.

 

yep your right i forget about the 93s.

alright if you have a 94 or up m6 you got 3.42s

 

Good call.
