Drive Range, Manual Second (from Drive, Manual Third): Notes

WARNING: This page is about a different variant/trim than selected.

When the gear selector lever is moved to the Manual Second (D2) gear range, the manual valve moves and allows line pressure to enter the D2 fluid passage. The transmission reacts by shifting immediately into second gear range and is prevented from upshifting into either Third or Fourth gear.
