thanks for your replies. The mechanics at the dealership didn't have the same answer. One said you have to slow down to around 35 mph before you go into 'L' and another said do it around/under 50. I guess I'll give it the old college try and see what happens. Its a little confusing since you only have the 'D' and 'L', I'm not use to that kind of transmission lever. At least its under warranty.
Ahh, I see...to be honest, I have not shifted it below 50, so maybe there is a limit. However, I don't think it will let you break it. Older cars used to physically lock the shift lever...I think the Acadia would simply not shift for you.
From the manual (this is the only section that I could find:
When you shift from DRIVE (D) to LOW (L), the
transmission will shift to a pre-determined
lower gear range. The highest gear available for
this pre-determined range is displayed next to
the L in the DIC. See Driver Information Center
(DIC) on page 232 and DIC Operation and
Displays (With DIC Buttons) on page 233 or DIC
Operation and Displays (Without DIC Buttons)
on page 239 for more information. The number
displayed in the DIC is the highest gear that
the transmission will be allowed to operate in.
However, your vehicle can automatically shift to
lower gears as required by various driving
conditions. This means that all gears below that
number are available. For example, when
FOURTH (4) is shown next to the L, FIRST (1)
through FOURTH (4) gears are automatically
shifted by the vehicle. You cannot shift into
FIFTH (5) until the plus (+) button is used or you
shift back into DRIVE (D) mode.
While in LOW (L), the transmission will prevent
shifting to a lower gear range if the engine speed
is too high for the gear range you are trying to
select. You have a brief period of time to slow the
vehicle speed. If vehicle speed is not reduced
within the timeframe allowed, the lower gear range
attempted will not be available. The highest
possible gear that is allowed for that engine speed
will display next to the L in the DIC. Try again
to slow the vehicle speed and press the minus (−)
button to the desired lower gear range.
