17. Install the A trim solenoid (15) so that the electrical connection faces up. Do not seat the solenoid.
18. Install the B trim solenoid (9) so the electrical connection faces up. Do not seat the solenoid.
19. Align 2 accumulator plugs (3) so that their spring bores face up.
20. Install 2 accumulator plugs (3) and 2 accumulator springs (2).
21. Push the A and B trim solenoids into their bores until the solenoids seat.
22. Align the A/B solenoid bracket (1) with the main valve body dowel pin (4).
23. Install the A/B solenoid bracket (10) so that the A and B trim solenoids, the accumulator plugs, and the accumulator springs are retained against the valve body.





24. Install 3 bolts (1) retaining the A/B solenoid bracket (2).

Tighten bolts to 12 Nm (9 ft. lbs.).
