These days with the computer controlled transmissions allot of times even seemingly very serious problems can just be a simple electrical problem. But I am leary of any automatic and would be very concerned with the long term effects and potential damage it may have caused. Although in this case if it feel like it shifts fine and just takes extra throttle it's probably not hurting anything, it sounds like it might just be in some sort of safety mode or dirty fluid, etc.
Every automatic I have ever had has failed on me
So that's where I am coming from when I say to stay away, manuals are so much more fun anyway. Real men shift for themselves
Admittedly transmissions have come a long way since the last auto I've had but I still don't like them.
Good luck, g37's are nice
