Question for the Mad Dr.

[Power Hungry]

I wonder if it does it in 4WD?

For some reason, I've noticed that the truck will go into a reduced power mode in Manual 2nd Gear. I'm not sure what the purpose of this is other than to prevent burning up the clutches in the transmission by trying to start from a dead stop in 2nd gear. I've never really been concerned about it since this is not a normal driving situation for most folks.

By the way, you can manually recreate the symptoms. Put the truck in 2nd and take off from a stop. At about 30 MPH, matt the gas pedal and after a second or two shift from 2nd to Drive. You'll instantly feel a change in power output. Make sure you're not downshifting when you switch to Drive or it makes the whole test pointless.
