OIL FILTER
REMOVAL
1. Put  container  under  the  oil  filter  to  prevent  oil  from
the oil filter from flowing out.
2. Use filter wrench to remove oil filter.
Filter wrench: 5-8840-0203-0
INSTALLATION
1. Apply engine oil thinly to oil filter O-ring.
2. Tighten  oil  filter  by  hand  until  O-ring  comes  in
contact with the sealing surface.
3. Use filter wrench to tighten oil filter one turn and 1/8
turn.
4. Start engine and carefully check for oil leakage from
oil filter.
SUB OIL FILTER 
The  sub  oil  filter  requires  no  servicing  until  the
replacement interval is reached.
The  element  is  designed  to  provide  special  filtering
efficiency until it becomes due for replacement.
It is recommended to check and replace the sub oil filter
when  the  engine  is  being  overhauled  or  if  it  is  broken
inside the engine.

7A–5 AUTOMATIC TRANSMISSION (4L30–E)
Normal Operation Of 2000 4L30–E
Tr a n s m i s s i o n
Torque Converter Clutch (TCC)
Application Conditions:
The  TCC  is  normally  applied  in  2nd,  3rd  and  4th  gears
only when all of the following conditions exist:
— The  engine  coolant  temperature  is  above  70
C
(158
F).
— The brake pedal is released.
— The shift pattern requests TCC apply.
Moreover,  TCC  is  always  applied  in  2nd,  3rd  and  4th
gears  when  the  transmission  oil  temperature  is  above
135
C (275F).
This mode should be canceled at 125
C (257F).
ATF Warning Lamp
The ATF warning lamp will be constantly on (not flashing)
if  the  transmission  oil  temperature  is  above  145
C
(293
F).
The  ATF  warning  lamp  goes  off  again  when  the
transmission oil temperature is below 125
C (257F).
Special Shift Pattern When The Engine Is
Cold:
A  special  shift  pattern  is  activated  when  the  engine
coolant temperature is below 70
C (158F). (3–4 shifts,
for example, are delayed for small throttle openings and
will occur a few MPH higher.)
Diagnosis
Introduction
The  systematic  troubleshooting  information  covered  by
this Section offers a practical and systematic approach to
diagnosing 4L30–E transmission, using information that
can be obtained from road tests, electrical diagnosis, oil
pressure checks or noise evaluation.
The key to correcting a complaint is to make use of all of
the available symptoms and logically letting them direct
you to the cause.
When dealing with automatic transmission complaints, it
is best to gather as many symptoms as possible before
making the decision to remove the transmission from the
vehicle.
Frequently,  the  correction  of  the  complaint  does  not
require removal of the transmission from the vehicle.
Driver Information
To analyze the problem fill out a complete description of
the owner’s complaint.
Please  draw  a  circle  around  the  right  information  and
complete  the  following  form.  (The  next  page  is  an
example  of  a  completed  form).  You  can  draw  a  circle
around many numbers if you are not sure.

7A–10
AUTOMATIC TRANSMISSION (4L30–E)
Checking Transmission Fluid Level
and Condition
Checking  fluid  level  and  condition  (color  and  odor)  at
regular intervals will provide early diagnosis information
about the transmission. This information may be used to
correct a condition that, if not detected early, could result
in major transmission repairs.
IMPORTANT:When new, automatic transmission fluid
is red in color. As the vehicle is driven, the transmission
fluid  will  begin  to  look  darker  in  color.  The  color  may
eventually appear light brown.
A  dark  brown  color  with  burnt  odor  may  indicate
excessive  fluid  deterioration  and  signal  a  need  for  fluid
change.
Fluid Level
When adding or changing fluid, use only DEXRON –III.
Refer  to  Maintenance  and  Lubrication  in  General
Information  section  for  maintenance  information  and
servicing interval.
CAUTION: DO NOT OVERFILL.
Overfilling  will  cause  foaming,  loss  of  fluid,  abnor-
mal  shifting  and  possible  damage  to  the  transmis-
sion.
1. Park the vehicle on level ground and apply the parking
brake firmly.
2. Check fluid level with engine running at idle.
NOTE: Be  sure  that  transmission  fluid  temperature  is
below 30
C (86F).
3. Move the selector lever through all gear ranges.
4. Move the selector lever to “Park”.
5. Let  engine  idle  for  3  minutes  and  open  the  overfill
screw (1).
6. Add released transmission fluid until it flows out over
the overfill screw opening.
7. Let engine idle until a fluid temperature between 32
C
(90
F) and 57C (135F) is reached, then close the
overfill screw (1).
Torque: 38 N
m (3.9 kgꞏm/28 lb ft)
NOTE: To  prevent  fluid  leaks,  the  overfill  screw  and  oil
drain  screws  gasket  must  be  replaced  each  time  these
screws are removed.NOTE: Check  transmission  fluid  temperature  with  scan
tool.
Minimum fluid level 
 57C (135F)
Maximum fluid level 
 32C (90F)
242RW003
CAUTION: Do  not  open  overfill  screw  with  engine
stopped.
CAUTION: DO  NOT  CHECK  FLUID  LEVEL  UNDER
THESE CONDITIONS:
Immediately  after  driving  at  sustained  highway
speeds.
In heavy city traffic during hot weather.
If vehicle is towing a trailer.
If the vehicle has been operated under these conditions,
shut the engine off and allow the vehicle to “cool” for thirty
(30)  minutes.  After  the  cool  down  period,  restart  the
vehicle and continue from step 2 above.

Chart 13: Shudder Only During Torque Converter Clutch (TCC) Applying
StepActionYe sNo
11. TCC  shudder  is  one  of  the  most  commonly  misdiagnosed
conditions  in  an  automatic  transmission.    The  key  to
diagnosing TCC shudder is to note when it happens and under
what  conditions.    Once  the  TCC  has  been  fully  applied,  it  is
nearly  impossible  to  make  it  shudder.    TCC  shudder  (short
burst  of  noise  normally  less  than  1  second)  will  only  occur
during clutch applying.  It is not a steady state condition.
2. Drive until whole drivetrain is at normal operating temperature.
– On 4WD vehicles, the test must be performed with transfer
case selector lever in “2H” position.
– Shudder is a short burst of noise normally less than 1 second
in duration, and can be induced by the following maneuver:
3. From coast condition at 50 mph in “D” range (Normal mode),
depress the throttle to 1/4-1/3 throttle. If present, shudder will
occur  within  5  seconds  together  with  TCC  application.(The
scan  tool  may  be  used  to  determine  the  exact  time  of  TCC
applying)
Was the problem found?
Replace
transmission fluid
and filter (remove
both pans) and
flush cooler lines.
Replace
converter
assembly and
O-ring on turbine
shaft
Perform
mechanical
inspection of
other drivetrain
components.
Chart 14: Possible Causes Of Transmission Noise
CAUTION: Before  checking  transmission  for  what
