Got it done already. Got an T1A4 TCM from GM for $260 and had Mike at Doug's Auto in Wisconsin flash it and the BCM for us. Allison DOC can't flash a GM cal. It's for medium duty only.
Current toys are as follows:
1961 Chevrolet Corvair Monza, 145 H6/powerglide. 85 HP of raw fury.... slow and stock and staying that way!

1970 GMC 9500, 6-71 Detroit/Fuller 13 speed, not sure why I bought it, but it sure is noisy!!!
