4T60 ratios and final-drive

My '90 Cutlass has the 4T60 transaxle with the optional 3.33 final-drive. Can anyone tell me what the ratios are for each gear on this particular transmission? Also, what other final-drives were available on this car and what is gained by the 3.33 upgrade? :?:

so does that .1 make the car accelerate slower? i realy think i should notice 20 more stock hp over a regular 3.1 more than i actually do...........either that or my motor is a total shitbox, and lately im really beginning to think that.

I'm surprised to hear that the 3.33 was all that was offered. I have the original window sticker for the car and under "Options" it has 3.33 final-drive listed. Thats why I assumed there where lower FDs available as standard equipment. But I assume you know more about that than me so you're probably right.

Something makes me think that 4T60s in other bodies may have had a different FDR (like a cavaliers or something), but Im not for sure. But 3.33 was all that was offered in Ws

I found the gear ratio spread sheet on brian89gp's site. Very informative and well presented. Since 3.33 was the only final-drive on W-body 4T60s, why did Olds even bother to put that on the window sticker under the options section? Weird.
