    How detrimental can it be to do that? I have an automatic (2006 TRD 4x4), and a couple of times I put it in neutral, switched over to 4 lo and then [sloppily] shifted into drive before the 4 lo annunciator stopped blinking... the result was a gear grinding fest until I quickly shifted back into neutral. Is this horrible for the xfer gears/linkages? I feel like my transmission has been behaving strangely since the last time this happened (lurching violently between gear shifts in 4 lo). Thoughts?

    Why are you shifting into neutral first? I just leave it in Drive and come to a stop before going into 4 Low. Never had a grind. I also have an '06 4x4 TRD

    Weird. Mine wont shift into 4 low unless it's in neutral. If I try, the 4 low annunciator blinks and the siren beeps until I put it into neutral and start over. Also, the operators manual says that it has to be in neutral to transfer to low.

    I think there is a difference between an AT vs. MT. The MT allows you to be in gear as long as the clutch is pressed. An AT must be in Park or Neutral.

    BTW - I think that is an improvement the Toyota needs to make. I have to try multiple times to get it into 4-Lo, especially when on a hill.

    Same here, and same with locking the diff. Sometimes it takes some serious fiddlefucking to get the diff to lock.

    No need to stop completely, a very slow roll is fine, and it will engage easier. But it must be in neutral.
