CVT Fluid CheckNLAT0025FLUID LEAKAGE CHECKNLAT0025S011. Clean area suspected of leaking. Ð for example, mating sur-
face of converter housing and transmission case.
2. Start engine, apply foot brake, place selector lever in ªDº posi-
tion and wait a few minutes.
3. Stop engine.
SAT288G
4. Check for fluid leakage.
SAT638A
FLUID CONDITION CHECKNLAT0025S02
Fluid color Suspected problem
Dark or black with burned odor Wear of frictional material
Milky pink Water contamination Ð Road water
entering through filler tube or breather
Varnished fluid, light to dark brown
and tackyOxidation Ð Over or under filling, Ð
Overheating

Stall TestNLAT0026STALL TEST PROCEDURENLAT0026S011. Check CVT fluid and engine oil levels. If necessary, add.
2. Drive vehicle for approx. 10 minutes or until engine oil and CVT
fluid reach operating temperature.
CVT fluid operating temperature:
50 - 80ÉC (122 - 176ÉF)

3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.
+It is good practice to mark the point of specified engine
rpm on indicator.
SAT514G
5. Start engine, apply foot brake, and place selector lever in D
position.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately
release throttle.
+During test, never hold throttle wide open for more than 5
seconds.
Stall revolution:
2,350 - 2,850 rpm
SAT771B
8. Move selector lever to ªNº position.
9. Cool off CVT fluid.
+Run engine at idle for at least one minute.

+Always replace pressure plugs as they are self-sealing
bolts.
SAT647B
LINE PRESSURE TEST PROCEDURENLAT0027S021. Check CVT fluid and engine oil levels. If necessary, add fluid
or oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and CVT
fluid reach operating temperature.
CVT fluid operating temperature:
50 - 80ÉC (122 - 176ÉF)

3. Install pressure gauge to corresponding line pressure port.
SAT513G
4. Set parking brake and block wheels.
+Continue to depress brake pedal fully while line pressure
test is being performed at stall speed.
SAT493G
5. Start engine and measure line pressure at idle and stall speed.
+When measuring line pressure at stall speed, follow the
stall test procedure.
Line pressure: Refer to SDS, AT-210.

Road TestNLAT0028DESCRIPTIONNLAT0028S01+The purpose of the test is to determine overall performance of
CVT and analyze causes of problems.
+The road test consists of the following three parts:
1. Check before engine is started
2. Cruise test
SAT496G
+Before road test, familiarize yourself with all test procedures
and items to check.
+Conduct tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
