WARNING:When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and/or damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING:Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds.Wash hands after handling.
To account for customer driving habits and conditions, your automatic
transmission electronically controls the shift quality by using an adaptive
learning strategy. The adaptive learning strategy is maintained by power
from the battery. When the battery is disconnected or a new battery is
installed, the transmission must relearn its adaptive strategy. Optimal
shifting will resume within a few hundred kilometers (miles) of
operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally or after a long
deceleration period, see your authorized dealer or a qualified
service technician as soon as possible.
Because your vehicle’s engine is also electronically controlled by a
computer, some control conditions are maintained by power from the
battery. When the battery is disconnected or a new battery is installed,
the engine must relearn its idle and fuel trim strategy for optimum
driveability and performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.

Parking Brake Fluid
Check and, if necessary, fill the
parking brake assembly to the
bottom of the filler plug hole (2)
(located on the driver side of the
transmission). Refer to
Maintenance product
specifications and capacitiesin
this chapter for the proper fluid
type.
Note:Do not fill the parking brake
through the vent plug (1) (located
on top of the transmission).
TRANSMISSION FLUID
Checking automatic transmission fluid
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.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool to normal operating temperature 150°F -
170°F (66°C - 77°C) before checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.

Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Maintenance product specifications and capacitiessection in this
chapter.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint (250 ml) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
An overfill condition of
transmission fluid may cause shift and/or engagement concerns
and/or possible damage.
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.
Automatic transmission fluid filter
The Torqshift automatic transmission is equipped with a serviceable
transmission fluid filter located inside the transmission bottom pan.
Refer toscheduled maintenance informationfor service intervals for
automatic transmission fluid and transmission filter.
For transmission filter maintenance, see your authorized dealer.

system. Fill to the Cold Fill Level on reservoir.2Add the coolant type originally equipped in your vehicle.3Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with in-tank cooler. The amount of transmission fluid and fluid level should be set by
the indication on the dipstick’s normal operating range.4Automatic transmissions that require MERCONLV should only use MERCONLV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.5Fill 1/4 inch to 9/16 inch (6 mm to 14 mm) below bottom of fill hole.
Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated for
life. These lubricants do not need to be checked or changed unless a leak is suspected, service is
required or the axle assembly has been submerged in water. The axle lubricant should be changed
any time the rear axle has been submerged in water.6Fill 1/4 inch to 9/16 inch (6 mm to 14 mm) below bottom of fill hole.
