I've been doing some research for my 4 speed auto project and I thought I'd share some information I've compiled. The following is a list of speedometer sender drive gears to suit ALL Borg-Warner / BTRE transmissions fitted from at least XD to AU and most likely others.
Diff ratio___Gear teeth number__Gear colour
2.77_____________18____________purple
2.92_____________19____________pink
3.08_____________20____________brown
3.23_____________21____________light green
3.45_____________22____________grey
3.50_____________23____________black
Please feel free to add others. This information was taken from various workshop manuals I have. I have C4 (and FMX) information too, I can post that if asked.
