Transmission Modification

[TURBOTAXI]

Hi,
I just thought I would see if anyone on this forum knows how to modify the AU transmission using resistors. A gentleman was going to help me, but I think he has been waylaid.
I have10 x 5 watt 33 ohm resistors (I think I need three) and I believe they are meant to go somewhere on the wiring for the trans. I just dont know where.
I looked at the mod on the AU falcon site, but it uses different resistors.
I have to drive to Sydney on Sunday and back on Monday I just want to give the trans an easier time.
Can anyone help me???
