Changed out both batteries. Automatic transmission will not go into forward or R on 1995 BMW 840Ci

I have a very low mileage 840CI (14,500 Miles). I believe I tripped something replacing both batteries in the trunk as the auto transmission will not go into forward or reverse.
Any way I can reset anything that I might have tripped?? Also, got Transmission Fail-Safe indication, but not getting that anymore. Radio will not accept code to reset either.
