2010 Mercury Mountaineer automatic transmission

Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.

WRECKER TOWING
Note:Turn off the power running boards (if equipped) prior to
preparing the vehicle for towing. Refer toPower deployable running
boardsin theDriver Controlschapter.
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift or flatbed
equipment. Do not tow with a slingbelt. Ford Motor Company has not
approved a slingbelt towing procedure.
If the vehicle’s battery is discharged, refer toAutomatic transmission
operationin theDrivingchapter for directions on how to move the
gearshift lever out of the P (Park) position, for proper towing.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
On AWD vehicles, it is required that your vehicle be towed with a wheel
lift and dollies or flatbed equipment with all the wheels off the ground.

BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the MIN and
MAX lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range, the performance of the
system could be compromised; seek
service from your authorized dealer
immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid
The automatic transmission does not have an underhood transmission
fluid dipstick.
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, (i.e., if the transmission slips or
shifts slowly) or if you notice some sign of fluid leakage.
Transmission fluid should be checked and, if required, fluid
should be added by an authorized dealer.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
