I knew it had 2 non-cvt ratios, but was not aware that selecting B limited the transmission to the lower one. So mow I'm not sure if the OP's problem is a failure to shift from the lower gear to the higher. It still could be I suppose; Assuming he used moderate throttle in D, the transmission might well get to the point of wanting to upshift to the higher ratio, and the system might be programmed to then react as he described if the transmission failed to shift to the higher gear.
Anyway, apparently the OP's problem has gone away (it didn't sound like it was really "fixed"), so this is just an interesting intelectual exercise. But I'll go and read my manual.
