Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to checkthe transmission fluid level. The onlyreason for fluid loss is atransmission leak or overheatedtransmission. If a small leak issuspected, use the followingprocedures to check the fluid level.However, if there is a large leak, itmay be necessary to have thevehicle towed to a dealer and haveit repaired before driving the vehiclefurther.
Change the fluid and filter at theintervals listed inMaintenanceSchedule0297,andbesuretousethe transmission fluid listed inRecommended Fluids andLubricants0305.
How to Check Automatic
Transmission Fluid
Because this operation can bedifficult, it is recommended to havethis check done at your dealer,which can monitor the transmissiontemperature. The transmission fluidlevel increases with temperature. Toobtain a highly accurate fluid levelcheck, the transmission temperaturemust be measured.
If it is decided to check the fluidlevel, be sure to follow all theinstructions here, or a false readingon the dipstick may occur.

1. Flip the handle up, pull out thedipstick, and wipe it with aclean rag or paper towel.
2. Push it back in all the way, waitthree seconds, and pull it backout again.
3. Check both sides of thedipstick, and read the lowerlevel. The fluid level must be inthe COLD (1) range for a coldcheck, transmissiontemperature 27 °C to 32 °C(80 °F to 90 °F); between theCOLD (1) and HOT (3) rangefor a WARM (2) check, 50 °C to60 °C (122 °F to 140 °F); or inthe HOT (3) cross-hatchedrange for a hot check, 71 °C to93 °C (160 °F to 200 °F). Besure to keep the dipstickpointed down to get anaccurate reading.
4. If the fluid level is in theacceptable range, push thedipstick back in all the way;then flip the handle down tolock the dipstick in place.
How to Add Automatic
Transmission Fluid
Refer toRecommended Fluids andLubricants0305to determine whatkind of transmission fluid to use.
1. WARM Range
2. HOT Range
Using a funnel, add fluid down thetransmission dipstick tube only afterchecking the transmission fluidwhile it is warm or hot. A cold checkis used only as a reference. If thefluid level is low, add only enough ofthe proper fluid to bring the level upto the middle of the WARM (1) orHOT (2) range depending on theambient temperature and priordriving conditions. Refer to“How toCheck Automatic TransmissionFluid”earlier in this section forinstructions on driving to achievewarm or hot transmission fluid.It does not take much fluid,generally less than 0.5 L (1 pt).

Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
1. Check the other vehicle.It must have a 12-volt batterywith a negative ground system.
Caution
If the other vehicle does not have
a12-voltsystemwithanegative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Get the vehicles close enoughso the jumper cables canreach, but be sure the vehiclesare not touching each other.If they are, it could cause a
ground connection you do notwant. You would not be able tostart your vehicle, and the badgrounding could damage theelectrical systems.
To a v o i d t h e p o s s i b i l i t y o f t h evehicles rolling, set the parkingbrake firmly on both vehiclesinvolved in the jump startprocedure. Put an automatictransmission in P (Park) or amanual transmission in Neutralbefore setting the parkingbrake.
Caution
If any accessories are left on or
plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting.
3. Turn off the ignition on bothvehicles. Unplug unnecessaryaccessories plugged into the
cigarette lighter or theaccessory power outlet. Turnoff the radio and all lamps thatare not needed. This will avoidsparks and help save bothbatteries. And it could save theradio!
