My "D" light blinks until the engine is warm

Yesterday I took off in the early morning with out side temp about 37. For the second time, the "D" on my shift indicator began blinking until the engine reached normal operating temp. Then it stoped and I was able to use the Tiptronic mode. The transmission did not act funny or shift erratically at any time.

Any ideas about the possible cause? Also, once I put the car in Drive -- my backup lights came on! Strange.

The dealer spent about an hour testing and found no codes in the computer. He thinks I may need a new tranny switch -- a pricey item with installation!

Any thoughts would be appreciated.

By the way, this is on my 1999 Boxster with 12K on the factory rebuilt engine and 1K on the RMS.
