greater than 8-10 inches. The converter clutch will
release when the transmission is down shifted out
of 4th gear or engine vacuum falls due to increased
throttle.
Step 6 —
Refer to
Figure 5.
If you desire more
control over the TCC you have a few options:
Option 1
will allow you to manually lock up the
torque converter in 2nd gear, 3rd gear and/or 4th
gear by running the green wire (Terminal B) to a
grounded dash mounted toggle switch.
Option 2
is for drivers that may want to shut down
the TCC system through a second dash mounted
toggle switch between to the red wire on the TCI
®
external harness (Terminal
A) and the switched 12-
volt source. Now, you may manually turn the lock
up system completely on and off.
Option 3
is for those who desire immediate release
of the TCC when braking. For this, you'll need an
OEM brake pedal switch with a normally closed
circuit. Run your switched 12-volt source through
the brake switch and then to the red wire on the
TCI
®
external harness.
Step 7 — Reinstall Transmission Pan:
Install a
new filter. Remove any pan gasket material that
may have been left on the transmission case/pan
during pan removal. Always replace transmission
pan
gasket
when
reinstalling
pan.
Refill
