Tundra [08/2014 - ]
HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
CAUTION:
The line pressure test should always be performed with at least 2 people. One person should observe the
Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature: 50 to 80°C
(122 to 176°F).
Be careful to prevent SST hose from interfering with the exhaust pipe.
This check must be conducted after checking and adjusting the engine.
Perform the test with the A/C OFF.
When conducting stall test, do not continue for more than 5 seconds.
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Turn the ignition switch off.
(3) Lift the vehicle up.
(4) Remove the test plug on the transmission case center right
side and connect SST.
SST: 09992-00095
09992-00231
09992-00271
(5) Lower the vehicle.
(6) Fully apply the parking brake and chock the 4 wheels.
(7) Start the engine and check the idling speed.
(8) Keep your left foot pressed firmly on the brake pedal and move the shift lever to D.
(9) Measure the line pressure when the engine is idling.

(10) Fully depress the accelerator pedal with your right foot. Quickly read the highest line pressure when
the engine speed reaches the stall speed.
(11) In the same manner, perform the test with the shift lever in R.

Title: AB60E AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: MANUAL SHIFTING TEST;
2015 MY Tundra [08/2014 - ]
MANUAL SHIFTING TEST
1. MANUAL SHIFTING TEST
HINT:
Through this test, it can be determined whether the trouble occurs in an electrical circuit or if it is a
mechanical problem in the transmission.
If any abnormalities are found in the following test, the problem is in the transmission itself.
HINT:
It is possible to deactivate the electrical shift control by
disconnecting the transmission wires. The gear positions can
then be changed mechanically with the shift lever.
(b) Drive the vehicle with the transmission wires disconnected. Move the shift lever to each position to check
whether the gear position changes as shown in the table below.
