2. Install the bolt.





60. Tighten the bolts in the sequence shown.





61. Inspect the lead frame for damage.
^ Using the special tool, check all lead frame solenoid connections. The gauge should fit tightly and not fall out after being inserted.
^ If the special tool passes through any lead frame connector pins or does not feel like it makes a good contact, install a new lead frame.





62. Connect the molded lead frame to the solenoids.
^ Connect the bulkhead inter-connector by pressing it in place by hand and fully seating the connector in place.
^ Connect the EPC solenoid by pressing it in place by hand and fully seating the connector in place. Make sure that the terminals pass fully through the connector slots.
^ Connect the TCC by pressing it in place by hand and fully seating the connector in place. Make sure that the terminals pass fully through the connector slots.
^ Connect the shift solenoid SSA and SSB by pressing it in place by hand and fully seating the connector in place. Make sure that the terminals pass fully through the connector slots.
