check engine CADILLAC ELDORADO 1994 10.G Service Manual

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Too much or too little fluid can damage your transaxle. Too
much can mean that some of the fluid could come out and fall\

on hot engine parts or exhaust system, starting a fire.
Be sure to
get an accurate reading
if you check your transaxle fluid.
Wait at least 30 minutes before checking the transaxle fluid level if you
have been driving:
When outside temperatures are above 90'F (32" C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal operating
temperature, which is
180 F to 200 ' F (82' C to 93 C).
Get the vehicle warmed up by driving about 15 miles (24 km) when
outside temperatures are above
50 "F (10'C). If it's colder than 50'F
(lO'C), you may have to drive longer.
To check the fluid level
Park your vehicle on a level place.
With the parking brake applied, place the shift lever in "P" (Park).
With your foot on the brake pedal, move the shift lever through each
gear range, pausing for about three seconds in each range. Then,
position the shift lever in
"P" (Park).
0 Let the engine run at idle for three to five minutes.

Refer to the Maintenance Schedule to determine what kind of transaxle
fluid
to use. See “Recommended Fluids and Lubricants” in the Index.
If
the fluid level is low, add only enough of the proper fluid to bring the
level into the cross-hatched area on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the dipstick hole to
bring it to
the proper level. It doesn’t take much fluid, generally less
than
a pint (OSL). Don’t overfill. We recommend you use only fluid
labeled DEXRON@-IIE or DEXRON@-111, because fluids with that
label are made especially for your automatic transaxle. Damage
caused by fluid other than DEXRON@-IIE or DEXRON@-I11 is not
covered by your
new vehicle warranty.
After adding fluid, recheck the fluid level as described under “How to
When the correct fluid level is obtained, push the dipstick back in all

the way.
How To Reset Transaxle Fluid Change Indicator:
Your vehicle is equipped
with a transaxle fluid change indicator. A
“CHANGE TRANS FLUID” message will display on the Information
Center when the power train computer determines that the transaxle
fluid needs to be changed or at each
100,000 miles (160,000 km) interval,
whichever occurs first. When this message appears, change the transaxle
fluid and reset the transaxle fluid life indicator as follows:
Turn the key “ON” with the engine stopped.
Press and hold the “OFF” and “REAR DEFOG” buttons on the climate
control simultaneously until the “TRANS FLUID RESET” message
appears in the Information Center (between
5 and 20 seconds).

if you have radial tires -- which may look properly' inflated even
if they're underinflated.
If your tires have valve caps, be sure to put them back on. They help
prevent leaks by keeping out dirt and moisture.
