8 Carefully remove the two cooler lines from the vehicle.
9 As required, separate the two cooler lines by removing the bracket and the two clips.
Reinstall
1 On the transmission end, ensure the spring clip and/or O-ring seal in each quick-connect fitting is not damaged, replace the complete fitting if required.

as required.
6 As a security check, push and clip each verification disc into place over the quick-connect fittings. If difficulty is experienced, repeat the installation process until the verification disc can be clipped into place over the
transmission quick-connect fitting.
7 Reinstall the transmission support, refer to 3.7 Transmission Support and Mount.
8 Remove the plugs from the cooler lines and radiator fittings and wipe all exposed parts clean.
