Disassembly
CAUTION: Do not touch the electrical connector pins or the exposed solenoid tabs on the transmission control module (TCM). An electrostatic discharge may occur and may cause damage to the TCM/Mechatronic assembly.
NOTE: Make an identifying mark on each solenoid and the corresponding bore for correct assembly.
NOTE: Solenoids may visually appear the same but their designs/functions are different. Caution must be taken not to assemble the Mechatronics assembly incorrectly. Incorrect solenoid installation will result in poor transmission shift quality.
NOTE: Note where the 8 check balls, 6 solenoid dampers, 2 internal valves and springs and 2 internal filters are located for reassembly.
Mechatronic assembly upper half
1. Make an identifying mark on each solenoid and the corresponding bore for correct assembly.
2. Remove the 6 long bolts from the TCM unit.
3. Carefully separate the TCM from the Mechatronic assembly.
4. Remove 19 short bolts from the Mechatronic assembly.
5. Separate the lower half of the Mechatronic assembly from the upper half of the Mechatronic assembly.
6. Remove and discard the separator plate.
7. Remove from the Mechatronic assembly the clips, caps, valves and spring from each bore. Note the location and order for reassembly. Refer to the exploded views.
8. Remove from the Mechatronic assembly the transmission control valves, check balls and filter screens. Note the location and order for reassembly. Refer to the exploded views.
9. Using clean mineral spirits, clean the upper half of the Mechatronic assembly.

10. Remove the 8 solenoid bracket bolts and the solenoid bracket.
11. Remove the solenoids.
12. Remove from the Mechatronic assembly the clips, caps, valves and spring from each bore. Note the location and order for reassembly. Refer to the exploded views.
13. Using clean mineral spirits, clean the lower half of the Mechatronic assembly.
Assembly
CAUTION: Do not touch the electrical connector pins or the exposed solenoid tabs on the TCM. An electrostatic discharge may occur and may cause damage to the TCM/Mechatronic assembly.
Mechatronic assembly upper half
1. NOTE: Many components and surfaces in the Mechatronic valve body are precision machined. Careful handling during disassembly, cleaning, inspection and assembly will prevent unnecessary damage to machined surfaces.
Install the clips, caps, valves and spring into each bore. Refer to the exploded views.

2. NOTE: Many components and surfaces in the Mechatronic valve body are precision machined. Careful handling during disassembly, cleaning, inspection and assembly will prevent unnecessary damage to machined surfaces.
Install the clips, caps, valves and spring into each bore.
3. NOTE: Lubricate the O-ring seals of the solenoids with clean automatic transmission fluid when installing them into the valve body.
Install the solenoids into their correct bores as indicated during disassembly.
4. Install the solenoid bracket and the 8 bolts.
