==Aussie Four Speed Gearbox:==

Officially called the M20 or M22 gearbox in a 6 cylinder car or the M21 when fitted to a V8.

M21's were also made for 6 Cylinder cars. (LJ XU-1's only)

End of submission by 383HGBrougham:

Thread1

===Ratios:===

Yes, a bit misleading there. The M20-21-22 designations refer to the ratios, regardless of whether they fit 6s or V8s.
M20 ratios:
1st & reverse - 3.05:1
2nd - 2.19:1
3rd - 1.51:1
4th - 1.00:1

M21 ratios:
1st & reverse - 2.54:1
2nd - 1.83:1
3rd - 1.38:1
4th - 1.00:1

===Draining the Gearbox:=== To drain the oil remove the rearmost and lowest cover bolt from the offside of the gearbox and catch the oil in a tin.

===Filling the Gearbox:=== When filling the gearbox make sure the drain bolt has been fitted and tightened down. Remove the large filler bolt in the nearside of the gearbox and place a tin under the hole. Pour in oil using an external funnel and a length of hose until the oil begins to run back out the filler hole and into the tin. When the oil stops draining out, install the filler plug and tighten it down.

===Aussie 4 Speed Gearbox With Cover TCS:===

Submission by TomKelly88

note that the rubber seal is located in the side cover not on the selector shaft itself unlike the other selector in this gear box and the selectors in earlier gearboxes.

End of submission by TomKelly88

 

===M22 Ratios:===

These are the ratios

M22 Ratios:

1st 3.74:1
2nd 2.68:1
3rd 1.68:1
4th 1:1,
rev 3.74:1

They where used in one tonners for pulling a lot of load, but for everyday if you dont need it dont get one cause the would give good acceleration bu otherwise be a nightmare.

Cheers

 

===Output Shaft:===

ALL TRIMATICS , AUSSIE 4 SPEED AND 3 SPEED all syncro have the same number and type of splines on the out put shaft only the early part syncro boxes had a course spline output shaft... v8 have a different size uni to sixes..
