St141 diff gear ratios

[troublesome_7]

Hey there

Just wondering if the diff ratios that came in the auto and manual cars were the same? Ive heard the manual one is 3.91, how about the auto?

Cheers

I am 99% sure st141 final drive is 3.89 for the 4sp and 5sp borg warner boxes. Auto I'm not 100% sure.

And i think the 22R coronas with the 5 Speed are taller like 3.45 or simmiler . The jap diff is 100% 3.58.
