The automatic transmission assembly performance test rig consists of two parts: the
bench part and the control cabinet part.
The bench part is equipped with a drive motor and an output eddy current loading
device.
The control cabinet part includes a control computer, oil pressure gauges, and motor-eddy current control equipment.
Equipment Introduction
Assembly Test Bench Transmission Control Unit
WE OFFER THREE TYPES OF AUTOMATIC TRANSMISSION PERFORMANCE TEST BENCHES:
Automatic Transmission Assembly Performance Test
Bench and Transmission Control Unit
Type 1: Equipped with both torque and
speed sensors, it can determine the completeness of gear engagement and test
shift smoothness.
Type 2: Equipped with speed sensors, it
can test gear engagement integrity and
calculate the gear ratio.
Type 3: A simple test stand that provides a
preliminary assessment of transmission
operating performance. It features a compact size, is easy to integrate into workshop
layouts, and offers high cost-effectiveness.
Different transmissions require different adapter plates. The dedicated adapter
plates we provide are the key to connecting the transmission to the tester. You
can quickly select the right plate based on the transmission model. From the
very design stage, each adapter plate has been developed with versatility in
mind, and can typically be perfectly matched to 5 to 6 types of transmissions.
This truly enables one plate for multiple uses, effectively reducing fixture costs
and improving testing efficiency.
For details, please refer to the operation manual.
TEST BOARD
We offer a variety of output shafts for different transmissions. You can flexibly select the
appropriate output shaft according to the specific transmission model.
OUTPUT SHAFT
For more detailed information, please refer to the operation manual.
Wire Harness Connector
Developed independently by Huadu Worldwide Automatic Transmission, we offer three transmission controller models suitable for
automatic transmissions (AT), continuously variable transmissions
(CVT), and dual-clutch transmissions (DCT), respectively. Each
controller is equipped with 13 output channels for controlling
solenoid valves, including 8 PWM (Pulse Width Modulation)
channels and 5 switching channels, supporting the testing of
9-speed, 10-speed, and even 12-speed transmissions.
In terms of signal acquisition, the controller can detect signals
from 4 speed sensors, 8 pressure sensors, and 2 temperature
sensors. Using the controller, you can perform shift operations on
the transmission and monitor all pressure and speed states in real
time during the shifting process.
During testing, the controller collects and stores data such as
pressure and rotational speed. You can upload the pressure and
speed data from each shift event (e.g., Reverse → Drive, Neutral
→ Drive, 1st → 2nd, 2nd → 3rd, etc.) to a personal computer for
subsequent shift quality analysis.
Please note that for different transmission models, you will need
to purchase the corresponding test wiring harness connectors
separately. In addition, we provide remote update services for the
test program via the internet.
TRANSMISSION CONTROL UNIT
CVT Transmission Controller Now, the CVT controller is applicable for testing the following transmission models:
CVT TRANSMISSION CONTROLLER CVT Test Controller can
switch between 2
modes freely: It can
either perform a fully
automatic test with one
click, or carry out
independent testing on
individual test items,
flexibly meeting the
in-depth needs of both
R&D and debugging.
? Secondary pulley oil pressure test
? Torque converter lock-up clutch oil pressure test
? Brake valve oil pressure test
? Clutch oil pressure test
? Accumulator valve oil pressure test
? Clutch clearance test and noise test (additional noise monitoring equipment required)

The CVT controller can regulate the working pressure of the primary pulley, detect the actual
oil pressure of the pulley in real time, and simultaneously monitor input speed, output speed,
transmission oil temperature, as well as oil pressure data of key components. It also supports
shift control.
AT Transmission Controller /
Hybrid Electric Drive Control Test Bench
AT TRANSMISSION CONTROLLER
The AT controller supports automatic testing functions, enabling
automatic shift execution while
displaying input speed, output
speed, and clutch operating pressures in real time. Additionally, the
controller supports manual upshift
and downshift operations, as well
as lock-up testing, meeting diverse
testing requirements.
The electric drive control tester is specifically
designed for testing the motor performance of
hybrid transmission systems. This device
supports motor speed input control, enables
forward and reverse rotation operations, and
accurately identifies the direction of motor
rotation. During testing, the operator can
perform speed increase, speed decrease, and
motor reset operations at any time. Meanwhile,
the system measures and displays key parameters in real time, including operating frequency,
output torque, output power, output voltage,
and output current.
HYBRID ELECTRIC DRIVE CONTROL TEST BENCH
Now, the AT transmission controller can test the following transmission models:
A960E TF-82
09G
红旗Hongqi TF-71SC 948TE 9T50 A6MF/A6LF
62TE U660E U760E 10R80 RE4F03B AL4/DP0 A6F7
6F24 A6F5 UB80E （More models are currently under development）
After completing a test, the transmission testing system can automatically upload data to a computer and generate variation curves that intuitively reflect the transmission's operating status. The
system supports one-click test report generation and automatically determines whether the transmission is pass/fail, significantly improving inspection efficiency and accuracy.
For TCU-integrated transmission products,
the controller simulates the Controller Area
Network (CAN) in a vehicle to control the
built-in TCU.

The valve body tester is available in two types
based on the test system: one is suitable for
automatic transmission (AT) valve bodies, and
the other is suitable for continuously variable
transmission (CVT) valve bodies. The equipment
supports shift testing, solenoid valve inspection,
oil pressure data acquisition, and shift timing
measurement, and features automatic testing
capabilities. The test time for a single valve body
is approximately 15 minutes, and a test report
can be automatically generated upon completion.
VALVE BODY TEST BENCH
We offer a variety of adapter plates
for different transmission valve
bodies. You can flexibly select the
corresponding adapter plate
according to the specific transmission model.
ADAPTER PLATE
The solenoid valve tester determines the operating
status of solenoid valves by collecting oil pressure
data. Based on the test results, it automatically
generates curve charts for easy comparison and
analysis, enabling accurate determination of
whether a solenoid valve passes the test. The
device provides free test data for various solenoid
valve models and supports remote updates of test
programs and data. By simply changing the test
fixture and wiring harness connectors, you can
quickly switch and perform immediate testing on
multiple solenoid valve models.
