Title: trimatic 3 spd convertion to Aussie 4spd M22
Post by: sjsargent on July 14, 2014, 08:30:35 PM: Hi guys,

Ive got a 202 3spd auto and im having issues with the shifting of gears and Hi revs. Does anyone have advice in regards converting to 4spd? would a Aussie 4spd M22 fit?

cheers,

sam

When converting from auto to manual dont forget to put the spigot bush in the end of the crankshaft.
The 4 speed ausie gearbox needs this.
The auto has a large round center on the torque convertor that slips into the crankshaft, where the manual gearbox has a thinner spigot shaft.
