I shifted to 5th.

I shifted a gear to 5th.

I shifted down from fifth to third.

Hi,

Yoong Liat was right. If out of the blue, we say, "Shift to second', it is confusing. However, if car enthusiats are talking about driving cars, the term gear can be omitted.

Then in the sentece below, the verb shift works as transitive verb and the sentece is correct, right?
You shift a gear to second.
