Mechatronic Assembly: Assembly
NOTE:
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.
Mechatronic assembly upper half
- Install the clips, caps, valves and spring into each bore. Refer to Fig 1.
Mechatronic assembly lower half
- Install the clips, caps, valves and spring into each bore.
- Install the solenoids into their correct bores as indicated during disassembly.
- Install the solenoid bracket and the 8 bolts.
- Tighten to 6 Nm (53 lb-in).
- Install the solenoid dampers, check balls, converter drain back valve and filter screens.
- Solenoid dampers
- Check balls
- Converter drain back valve
- Small screen
- Big screen
- Empty hydraulic passage (no check ball)
- Align the guide pins on the TCM
with the holes in the upper valve body and install the valve body on the TCM
.
- TCM
- Upper valve body
- Guide pins
- Position the separator plate on the upper valve body.
Check the 2 drain back valves to be sure they are correctly positioned in the separator plate when the separator plate is pressed flush against the upper valve body.

- Drain back valves
- Position the lower valve body on the 2 TCM
alignment studs, align the manual valve with the Transmission Range (TR) sensor on the TCM
and install the lower valve body.
- Lower valve body
- Manual valve
- TR sensor
- Install the 6 (long) TCM -to-valve body bolts hand-tight.
- Install the 19 (short) mechatronic assembly lower-to-upper valve body bolts.
- Tighten the bolts in the sequence shown.
- Tighten bolts 1 through 6 in the tightening sequence to 7 Nm (62 lb-in).
- Tighten bolts 7 through 25 in the tightening sequence to 6 Nm (53 lb-in).
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.

NOTE:
Lubricate the O-ring seals of the solenoids with clean automatic transmission fluid when installing them into the valve body.
NOTE:
Towards the back of the upper valve body there is a hydraulic passage that is shaped as though it receives a check ball. This passage does not require a check ball. Be sure not to mistake this hydraulic passage for a passage that does require a check ball or damage to the transmission can occur.
NOTE:
If the drain back valves are not installed correctly in the separator plate, damage to the transmission can occur.
