I would really appreciate at least one example of this. I know this is a Mopar forum but I also have a couple AMC's with the T-10. AMC deliberately went from the 2.64 and 2.43 first gear ratios to the 2.23 to get a higher transmission torque rating. I'm thinking about putting the 2.64 first gear ratio behind a warmed over 401 and wondering if that is a prudent move. T-10 information can be confusing. I am under the impression that there was the original T-10, then the First Generation Super T-10 that was developed in the mid-'60's with the Second Generation super T-10 being developed in the mid '70's. But I can't back any of this up.
