Mechatronic Assembly: Disassembly

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.

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 mechatronic 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.
