TROUBLE-SHOOTING AND DIAGNOSES
Preliminary Checks
(Prior to Road Testing)
FLUID LEAKAGE
To detect a fluid leak
1) Raise vehicle
2) Clean area suspected of leaking
3) Start engine, apply foot brake, place control
lever in drive, and wait a few minutes
4) Stop engine
5) Check for fresh leakage
FLUID CONDITION
Examine the AT F and note its color, texture,
and odor
1) Dark of Black Fluid
With a burned odor
- Worn friction material
2) Milky Pink Fluid Water Contamination
- Road water entering through filler
tube or breather
3) Varnished Fluid, light to dark brown and
tacky Oxidation
- Over or Underfilling
- Overheating
- Road Testing
Before starting road tests, install vacuum gauge
SAT596
Perform road tests, using "Symptom" chart, as
follows
"P" RANGE
1 Place the control lever in "P" range and start
the engine Stop the engine and repeat the
procedure in all other ranges and neutral
2. Stop vehicle on a slight upgrade and place con-
trol lever
in "P" range Release parking brake
to make sure vehicle remains locked
"R" RANGE
1 Manually shift the control lever from "P" to
"R", and note shift quality
2 Drive the vehicle in reverse long enough to
detect slippage or other abnormalities
"M" RANGE
1 Manually shift the control lever from "R" and
"D"
to "N" and note quality.
2. Release parking brake with control lever in
"N" range Lightly depress accelerator pedal to
make sure vehicle does not move (When
vehicle
is new or soon after clutches have been
replaced, vehicle may move slightly This
IS not
a problem )
"D" RANGE
1 Manually shift the gear selector from "N" to
"D" range, and note shift quality.
