Is final drive ratio a concern?
I found the following in my search:

So the number is the same for the B235E 2.3LPT engine as well as the B308E 3litre V6
The final drive ratio is dictated by the 4th character of the code i.e. the 7
The 5th character indictaes which engine it was "adapted" for. A= the LPTs and 3.0 petrol, C=Aero. AFAIK the Aero boxes had a beefier torque converter.
