not cut o-rings during reinstallation, Fig. #10 & 11.
STEP #18:
Connect case connector wires, Fig. #12. Note how wires are routed around the spacer to
prevent interference with dip stick. The front solenoid wire (converter side of manifold), goes
to the case connector Yellow or Black wire. This is your 1-2 Shift wire connection.
YOU MUST DO THIS RIGHT OR YOUR TRANSMISSION WILL NOT WORK PROPERLY.
STEP #19:
Connect the case connector White wire to 2-3 Shift solenoid wire connection, Fig. 13 & 14.
