| Dismantling, assembly | ||
| Pay attention to extreme cleanliness for all work on the shift valve housing. Do not use any fluffy cloths | ||
1 | Unscrew screws (arrows). | Installation: Tighten screws (arrows) only slightly so that both parts of the housing cannot move relative to each other. | |
2 | Remove valves (13, 24, 86) and chip screen (33a) | ||
| Primary pump non-return valve dispensed with | Transmission 722.5 | |
3 | Hold shift valve housing (A) and damper housing (B) together and turn over | ||
4 | Carefully lift damper housing (B) with intermediate plate | ||
| Small intermediate plate modified | Transmission 722.5 | |
5 | Remove all 19 valve balls (14) | The valve ball marked with number 14 is on a conical spring | |
6 | Remove valves, filter and shift pin | ||
7 | Unscrew side cover from shift valve housing | Check piston and valve for movement and chips, only if necessary. | |
The springs are installed upstream or downstream of the valve, depending on the transmission or vehicle model. | |||
8 | Adjust full throttle control pressure | Adjust full throttle or kick-down upshift. | |
9 | Assemble in reverse sequence |
