3. TRANSMISSION FILL
(a) Fill the transmission with the correct amount of fluid as
listed in the table below.
(b) Reinstall the refill plug to avoid fluid splash.
RepairFill Amount
Transmission pan and drain plug remov-
al1.3 liters (1.37 US qts, 1.14 Imp. qts)
Transmission valve body removal3.9 liters (4.12 US qts, 3.43 Imp. qts)
Torque converter removal5.3 liters (5.60 US qts, 4.66 Imp. qts)
Entire transmission assembly5.3 liters (5.60 US qts, 4.66 Imp. qts)
HINT:
If you cannot add the listed amount of fluid, do the following:
(1) Install the refill plug.
(2) Allow the engine to idle with air conditioning OFF.
(3) Move the shift lever through entire gear range to cir-
culate fluid.
(4) Wait for 30 seconds with the engine idling.
(5) Stop the engine.
(6) Remove the refill plug and add fluid.
(7) Reinstall the refill plug.
4. FLUID CIRCULATION
(a) Allow the engine to idle with the air conditioning OFF.
(b) Move the shift lever through entire gear range to circulate
fluid.
5. FLUID TEMPERATURE CHECK
NOTICE:
The fluid temperature should be less than 30C (86F) be-
fore beginning the fluid temperature check.
(a) With hand-held tester
(1) Connect the hand-held tester to the DLC3.
(2) Select the tester menus: OBD/MOBD, ENGINE,
DATA LIST and A/T.
(3) Check A/T OIL TEMP.
(4) Allow the engine to idle until the fluid temperature
reaches 46C (115F).

(b) Without hand-held tester (Using A/T OIL TEMP indicator)
(1) Connect terminals between CG (4) and TC (13) of
the DLC3 using SST (09843-18040).
(2) Move the shift lever back and forth between N and
D at 1.5 seconds interval for six seconds.
(3) The D shift indicator on the combination meter
comes on for two seconds. This indicates that the
fluid temperature check mode has been started.
(4) The D shift indicator comes on again when the fluid
temperature reaches 46C (115F) and blinks
when it exceeds 56C (130F).
(5) Allow the engine to idle until the fluid temperature
reaches 46C (115F).
6. FLUID LEVEL CHECK
NOTICE:
The fluid temperature must be between 46C (115F) and
56C (130F) to check the fluid level.
(a) Remove the overflow plug with the engine idling.
(b) Check that the fluid comes out of the overflow tube.
If fluid does not come out, proceed to step 7.
If fluid comes out, wait until the overflow slows to a
trickle and proceed to step 8.
7. TRANSMISSION REFILL
(a) Install the overflow plug.
(b) Stop the engine.
(c) Remove the refill plug.
(d) Add 0.4 liters (0.42 US qts, 0.35 lmp. qts) of fluid.
(e) Allow the engine to idle and wait for 10 seconds.
(f) Proceed to step 6.
8. COMPLETE
(a) Install the overflow plug with a new gasket.
(b) Stop the engine.
(c) Install the refill plug with a new gasket.
Torque:
20 NVm (205 kgfVcm, 15 ftVlbf) for overflow plug
39 NVm (400 kgfVcm, 29 ftVlbf) for refill plug
