Flushing automatic transmission valve body valves
The automatic transmission valve body is a complex electronic device that controls the flow of fluid in the gearbox. Over time, the valves inside the valve body can become dirty and worn out, leading to shifting problems, fluid leaks and other problems. Flushing the valve body valves is an important step in transmission maintenance and can help eliminate these problems.
Stages of flushing automatic transmission valve body valves
1. Removing the valve body. To access the valve body, it is necessary to remove the transmission pan and disconnect the valve body from the automatic transmission housing.
2. Disassembling the valve body. The valve body is disassembled into its component parts, including valves, solenoids and seals.
3. Cleaning components. All valve body components are thoroughly cleaned with solvent or special solutions to remove dirt, metal shavings and other contaminants.
4. Checking valves. The valves are checked for wear, scratches and other damage. Damaged valves must be replaced.
5. Assembling the valve body. The cleaned and tested components are assembled back into the valve body. Particular attention is paid to the correct installation of valves and seals.
6. Installation of the hydraulic unit. The valve body is installed back into the transmission housing and connected to the hydraulic system.
