General Installation Practices
1. Familiarize yourself with the installa-
tion procedure by reading the installation
manual before starting work.
2. Throughout this manual, the left side
of the vehicle refers to the driver’s side,
and the right side refers to the passenger’s side.
3. Disconnect the negative (ground)
cable from the battery (or batteries, if
there are two) before beginning work.
4. Route and tie wires and hoses
7. Installing the Banks Torque Convert-
er requires removal of the transmission
from the vehicle. Heavy tooling such as
a transmission jack and an automotive
hoist or ample-height jack stands are
required. Professional installation by a
properly equipped shop is recommended. Failure to follow all installation
instructions during Torque Converter
install can result in bodily injury and/or
expensive damage to the transmission
and surrounding components.

area and tools clean to avoid possible
entry of dirt into the drivetrain.
6. When raising the vehicle, support it
on properly weight-rated safety stands,
ramps or a commercial hoist. Follow
the manufacturer’s safety precautions.
Take care to balance the vehicle to
prevent it from slipping or falling. When
using ramps, be sure the front wheels
are centered squarely on the topsides.
When raising the front of the vehicle,
set the parking brake and block the
rear wheels. When raising the back of
the vehicle, be sure the vehicle is on
level ground and the front wheels are
securely blocked.
verter must be removed as an assembly to avoid damage to the converter
drive plate, pump bushing and oil seal.
Converter, verify that your transmission is in good operating condition.
Transmission problems such as harsh
or delayed engagement when shifting into Drive or Reverse, no Drive or
Reverse range, erratic shifting, grating
or scraping noises, or lack of up and/
or downshifting can lead to torque converter damage. If necessary, have your
transmission repaired or overhauled
before installing the converter.
Caution! Do not use floor jacks to
support the vehicle while working under it. Do not support the
vehicle using concrete blocks,
masonry or any other item not
intended specifically for this use.
