Note: this procedure should only be
performed if:
(a) A ”4,2” code for transmission slip
detection is repeatedly set or will
not clear and the transmission is not
actually slipping; or
(b) The Six-Gun Diesel Tuner is moved
to a new vehicle; or
(c) The speedometer has been
recalibrated for different gearing or tire
size; or
(d) Instructed to do so by Banks
Technical Staff.
Your Six-Gun Diesel Tuner also has
the capability to clear the information
related to the learned transmission
type and gear ratios. The diagnostic
code “4,3” will reappear after the
procedures are carried out correctly.

position but DO NOT start engine.

remains in stock level until the Six-Gun
Diesel tuner re-learns the transmission
and code “4,3” is eliminated. Follow the
