Shandong Huashou Transmission Technology Co., Ltd. is one of the leading manufacturers and suppliers of electronically controlled power-shift transmission in China. With abundant experience, we are committed to providing high quality customized products with competitive price. Welcome to wholesale bulk durable electronically controlled power-shift transmission in stock here from our factory. Also, pricelist is available.
Products Description
The transmission contains four planetary rows and five disc clutches. The first two planetary rows and their associated clutches handle the forward/reverse direction, while the other planetary rows and clutches are used for first, second and third gear selection.
The power path starts from the engine, passes through the torque converter and universal joint, then enters the transmission through the input coupling and main shaft. From there, power moves through the planetary gear sets and clutch assembly before reaching the output shaft.
The 325hp electronically controlled power-shift transmission wording should be used carefully on the website because the supplied manual specifically describes hydraulic control through a control valve, rather than providing details of an electronic control unit. Therefore, the product should not be described as having an ECU or electronic control system unless separate technical documentation confirms it.

Product Features
3 Forward + 3 Reverse
The transmission provides six defined ratios. Each ratio is obtained through a specific clutch combination.
01
Multi-Planetary Construction
The four planetary rows are arranged for direction and speed control. The second planetary row uses a double-planet structure, while the other three use single-planet transmission.
02
Five Disc Clutches
Clutches 1–4 work as braking clutches, while clutch 5 connects the main and driven members for synchronized rotation.
03
Hydraulic Pressure Control
The control valve uses hydraulic pressure to engage the required two clutches for each selected gear.

Product Advantages
For bulldozer operation, the electronically controlled power-shift gearbox keyword describes the target transmission category, but the actual supplied manual describes a hydraulically actuated clutch system.
A useful feature of this structure is that the same basic transmission assembly provides both direction changes and three travel speeds through different clutch combinations. The forward and reverse ratios are clearly defined, making the transmission specification straightforward to match with the corresponding machine requirement.
The unit is also supported by defined operating oil requirements. The manual specifies No. 6 or No. 8 hydraulic transmission oil and requires the oil to be properly filtered before use.
Product Applications
The TY320 transmission can be used in bulldozer powertrain applications involving:
- Earthmoving
- Construction work
- Forward and reverse travel
- Multi-speed operation
- Frequent gear selection
- High-torque drivetrain operation
- Transmission replacement or refurbishment
The Electronically Controlled Power-Shift Transmission keyword can be targeted on the product page for users searching for power-shift transmission solutions, while the technical description should remain consistent with the hydraulic control structure stated in the manual.
Customization Options
For applications requiring a different transmission configuration, customers can submit the existing gearbox information for comparison.
Useful technical information includes:
- Machine and transmission model
- Input power
- Input speed
- Input torque
- Required gear ratios
- Hydraulic pressure requirements
- Installation drawings
- Existing transmission photographs
- Relevant maintenance or technical documents
The Electronically Controlled Power-Shift Transmission keyword can be used as a search term for the product category, while any actual electronic-control requirements should be confirmed separately because the supplied TY320 manual describes hydraulic clutch control rather than an electronic control unit.
FAQ
Q: How many forward and reverse speeds does the TY320 transmission have?
A: It has three forward speeds and three reverse speeds. The forward ratios are 2.86, 1.52 and 0.83; the reverse ratios are 2.36, 1.25 and 0.68.
Q: What is the maximum input torque?
A: The maximum input torque is 3,982 N·m, with a maximum input speed of 2,000 r/min.
Q: How many planetary gear sets are used?
A: The transmission contains four planetary gear sets and five disc clutches.
Q: How is gear selection controlled?
A: The manual states that the control valve uses hydraulic pressure to engage the required two clutches for the selected speed and direction.
Q: What transmission oil is specified?
A: The manual specifies No. 6 or No. 8 hydraulic transmission oil. The oil should be properly filtered before being added to the system.
Q: When should the transmission oil be replaced?
A: According to the maintenance schedule, transmission oil should be replaced at the 600-hour maintenance interval, together with cleaning the oil pan and oil filter.
Q: What should be checked if the clutch slips?
A: The manual lists low control oil pressure, a blocked oil filter, blocked oil passages and worn friction plates among possible causes. The corresponding checks include inspecting the control valve, cleaning the filter or oil passages, and replacing worn friction plates.
