AOD-E Rev Limiter and Wide Ratio Gear Set

I may be faced with the problem of changing the planetary gears (very loud whine in first) and having to install a wide ratio gear set (4R70W). This change may require a custom powertrain control chip to over ride the rev limiter setting for the AOD-E which I believe is set at 5250 rpm. If my present 1-2 shift is at 5000 rpm with the wide ratio gears this will change to 5915 rpm well beyond the PCM limiter setting. Have I got this correct?

I'm certain a few of you have gone through this exercise so I'd appreciate hearing how you resolved this issue or if indeed it was an issue.

The wide ratio gear set is a direct replacement making it an AOD-EW/E4R70W.
Now I'm wondering what was reprogrammable in my Transgo HD2 kit besides speed and firmness.

I was thinking that the earlier shift points wouldn't be an issue any more than shifts with the 3:73 gear set. Shifts appear to be determined by speed not engine rpm under light(er) throttle. I'll post a new thread asking about the Baumannator TCS electronic transmission controller.
