Dismantling the shift plate
74 - Valve assembly; 74.14 - Control valve for switching on 1-2 / 4-5 gears; 74.15 - Valve for fixing the inclusion of 1-2 / 4-5 gears; 74.18 - 1-2/4-5 overlap adjustment valve with sleeve and piston; 74.19 - Gear change pressure control valve; 74.20 - Control valve pressure control valve; 74.21 - Switch valve pressure control valve; 74.22 - Torque converter blocking adjustment valve; 74.24 - Pressure switching valve when 3-4 gears are turned on; 74.25 - Control valve for switching on 2-3 gears; 74.26 - Valve for fixing the inclusion of 2-3 gears; 74.27 - Switching valve B2
1. Loosen the fasteners (82).
2. Remove the bolts (71).
3. Remove valve cover (72) from valve assembly (74).
4. Remove the sealing plate (73). All 12 balls are located in the valve body, four 75 of which are plastic, the remaining eight (76) -steel.
5. Turn away covers of the case of valves. Control valve bushings and pistons (72.2), (72.8) And (74.18) should not be mixed.
6. Changeover valve B2 can be removed and installed when the valve body cover is removed.
Assembly
Dismantling the shift plate
59 - Guide pin; 75 - Plastic ball valves; 76 - Steel ball valves; 143 - Central lock
Assembly is carried out in the reverse order of disassembly. Insert guide pin (59) into the valve body (arrow).
