No trimatics were chev pattern. The easiest way to bolt up a manual GMH 3 speed to a chev is use the GMH chev bellhousing off a 4 speed box.You will have to use the chev flywheel and put the holden clutch on it for the right spline match,as well as a spigot bearing/bush match,you will have to check input shaft length.If you use a 6 cyl box you will have to machine the bellhousing face as they have shorter input shafts than the v8 boxes{you can swap the v8 and 6 shafts in most boxes} If you want to use the 3 speed trimatic then you will have to use a redrilled flexi plate and modified bellhousing.But then why would you want a trimatic !Im guessing you are wanting a manual!

try and source a New Zealand new 3 spd chevy box and put the whole deal into the holden or a yankee one but use the crossover system down on the box and use the column shift. If yur lucky you may get a 3 spd and overdrive chev column box, that would be real cool in a holden.

is it manual!i once measured up the possibility of putting a slant six into my mate's manual hq ute (cos slant sixes are awesome and the 202 would barely get out of it's own way-and use pretty much as much gas to boot.) but the wiper motor was gonna be in the way :-(then he was told its pretty easy to put a holden v8 into it. never got around to it tho and in the meantime i think it just gets used for short trips where no hills are expected lol.
