Cadillac deville 1999 User Manual

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 (10_C), you may have

to drive longer.

D Park your vehicle on a level place. Keep the 

engine running.

D With the parking brake applied, place the shift lever

in PARK (P).

D 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 PARK (P).

D Let the engine run at idle for three to five minutes.

Then, without shutting off the engine, follow these steps:

1. The black transaxle fluid cap is located next to the

radiator hose and below the air cleaner assembly on
the driver’s side of the engine. Remove the air
cleaner assembly so you can reach the transaxle fluid
cap. The assembly is attached to the vehicle by two
fasteners. Lift up on the air cleaner assembly to
remove it. Find the transaxle fluid cap and turn it
counterclockwise to remove. Pull out the dipstick
and wipe it with a clean rag or paper towel.

2. Push it back in all the way, wait three seconds and

then pull it back out again.
