[ROVERNET - UK] sd1 borg-warner 65 torque converter question

My first thought is the kickdown cable. That will
change the performance of the car completely. If the
unit worked fine before than by the installation of
the unit into the newer car, I am sure that you have
changed the cable connection.
Hope that helps.
