A#1 The center distance on our transaxle is much larger than any other transaxle allowing us to place all the shifting elements on the primary shaft. That is where they belong.
A#2 Depending on the application Bonneville for instance all the ratios in the transmission were overdriven to get the desired speed 400 plus mph with a 31 inch tire a 2.29 gear ratio and a KB 1671 blown 510 cid engine. In this case there was not a taller final drive gear made (2.08 and 2.13 very rare) for a 12 bolt.
In any design there is a compromise. To get the low (granny gear) and the top speed (using an existing transaxle) you will need an overdrive. If you are designing from scratch you try not to do that.
