When connecting or disconnecting connectors to or from the TCM, be careful not to damage the connector terminals (neither bend nor break). Before connecting the connector, make sure that the connector terminals are not bent or broken.
After performing diagnostics of the malfunction, it is necessary to perform the procedure "Checking the fault codes". After the repair is performed, the procedure "Checking the fault codes" should not reveal the presence of fault codes.
Use in the automatic transmission only the working fluid that is prescribed by the technical specifications.
When carrying out repair work, use special paper that does not leave fibres instead of rags.
Used working fluid (ATF) must be disposed of in accordance with the procedure established by law.
Before disassembling the gearbox, thoroughly clean the outer surfaces of its housing. It is very important to take the necessary measures to prevent contamination of the contour parts.
Disassembly should be carried out in a clean place.
Use lint-free paper to wipe the parts. Regular rags can become frayed, and the threads can cause the automatic transmission to fail.
Lay out the parts of the disassembled automatic transmission in an order convenient for subsequent assembly.
Before checking and assembling, all parts must be thoroughly cleaned with a non-flammable solvent.
Gaskets and sealing rings must be replaced at each overhaul of the automatic transmission.
The valve box contains precision parts, and its disassembly and maintenance require special care. Lay out the parts of the disassembled valve box in an order convenient for subsequent assembly. Take all measures to prevent the loss of springs and other small parts.
When installing valves, bushings and plugs, do not apply force. They should enter the holes under their own weight.
Before assembly, lubricate the parts with the recommended working fluid. To protect the sealing rings and seals, as well as to position the bearings and washers during assembly, use technical petroleum jelly. Do not use consistent grease.
Special care must be taken during assembly with regard to O-rings, gaskets and seals.
After assembly, fill the automatic transmission with new working fluid.
When you unscrew the drain plug from the automatic transmission, only part of the working fluid is drained. Some of the old working fluid remains in the automatic transmission radiator and in the torque converter.
