I got an automatic 94 T/A. Wondering what size gear I have. I was told that I might have a 3.23. I was under the impression that I had a 3.42. mabey not. What do ya tink???
Thanks Ya'll

 

RPO codes on the door jab or glove compartment.
GU2 2.73 Ratio
GU5 3.23 Ratio

 

Automatics did not come with 3.42s.

 

what's your rpm at 60 mph?

 

is "1" selectable on the shifter>?

 

Yea, 1st is there and I got the shift performance button, but I don't think that's gonna make a difference. If I accually have a 3.23 should I bother bumping it up to a 3.42 or a 3.73. I want the accleration but I don't want to be screaming down the highway when I'm trying to deive long distance. Ya do ya'll tink?

 

If you have 1st gear selector then you have 3.23's.

 

mine does not have the 1st gear selector, i suppose i have 273's, so what happens if i swap for 323's one day, what do i do to select 1st gear, i know you have to remove the block thing, but what do i do with the consol, do i have to buy one that says 1st gear, or do u have to make any modifications to the existing one.

 

If I accually have a 3.23's should I bother bumping it up to a 3.42 or a 3.73. Is it gonna make that much of a difference in my track times? I ran a 14.1 so far and can't figure out why I'm not running high 13's. I want the acceleration but I don't want to be screaming down the highway when I'm trying to drive long distance. Ya do ya'll tink?

 

Open Your glove compartment at look for the RPO code. It's that easy. I'd go with 3.73's if I were worried about higher RPM's. Although I still think my 4.10's aren't that bad.
