F: ADJUSTMENT
1) Using the ST, measure the height “A” from the
AT main case mating surface to convex surface of
oil pump cover.
ST 499575400 GAUGE
2) Using the ST, measure the depth “B” from the
convex surface of oil pump cover to thrust bearing
transferring surface.
ST 499575400 GAUGE
3) Calculate the measured value from step 1) and
2), and then set the calculated value as “C”
Calculation formula: C = A – B
4) Using the ST, measure the depth “D” from the
AT main case mating surface to thrust bearing
transferring surface of front sun gear.
ST 499575400 GAUGE
5) Set the value as “E” which subtract the thickness
of ST (GAUGE) from the measured value on step
4).
Calculation formula: E (mm) = D – 15
[E (in) = D – 0.59]
6) Calculation formula:
Select one thrust bearing from the table to adjust
clearance within 0.25 — 0.55 mm (0.0098 — 0.022
in).
When clearances are 0.25 mm (0.0098 in):
T (mm) = E – C + 0.03
[T (in) = E – C + 0.0012]
When clearances are 0.55 mm (0.022 in):
T (mm) = E – C – 0.27
[T (in) = E – C – 0.012]
T: Thrust needle bearing thickness
C: Distance from oil pump cover mating surface to
rear end of oil pump cover
E: Depth from mating surface of AT main case to
bearing surface of front sun gear
NOTE:
Calculation formula for “T” above is applied when
measuring with the ST (499575400 GAUGE). In
the calculation without using ST, substitute the
thickness of collar used to calculate the value “E”
on step 5).

A: PROCEDURE
Step Check Yes No
1CHECK PRE-INSPECTION.
1) Ask the customer when and how the trou-
ble occurred using the interview checklist.

2) Before performing diagnosis, inspect the
following item which might influence the AT
problems.
•General inspection INSPECTION, General Description.>

A: CAUTION
•SRS AIRBAG SYSTEM
The airbag system wiring harness is routed near
the TCM.
CAUTION:
•All air bag system wiring harnesses and con-
nectors are colored yellow. Do not use an elec-
tric test equipment to check these circuits.
•Be careful not to damage the airbag system
wiring harness when performing diagnostics or
servicing the TCM.
•MEASUREMENT
When measuring the voltage and resistance of the
ECM, TCM or each sensor, use a tapered pin with
a diameter of less than 0.64 mm (0.025 in) in order
to avoid poor contact. Do not insert a pin of more
than 0.65 mm (0.026 in) diameter.
