Mechatronic Assembly: Assembly

Mechatronic assembly upper half 

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: 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.
5. Install the solenoid dampers, check balls, converter drain back valve and filter screens.

   2. Check balls
   3. Converter drain back valve
   4. Small screen
   5. Big screen
   6. Empty hydraulic passage (no check ball)

NOTE: The separator plates are different between the early and late build mechatronic assemblies to accommodate the different number of dampers. Failure to install the correct separator plate can result in harsh, soft or erratic shifts or damage to the transmission.
NOTE: If the drain back valves are not installed correctly in the separator plate, damage to the transmission can occur.
7. 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.

10. Install the 19 (short) mechatronic assembly lower-to-upper valve body bolts.
    • Tighten the bolts in the sequence shown in the illustration.
    • 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).
