Fault finder chart

Using this chart it should be possible to pinpoint where a fault lies in your Borg Warner gearbox.

Put a tick in the "Drive" column for each working gear, it should then be possible to see which part of your auto box isn't working.

For example if you have drive in all forward gears except D1/1 and no reverse the problem is with the rear brake band. No forward gears means the front clutch has burnt out etc.

Before beginning tests ensure that:
A) The fluid is in good condition
B)The fluid level is correct
C) Basic settings are correct
D) Engine is in a good state of tune
