m22 gearbox

[wal]

hi
will an m22 gearbox out of a 1tonner fit in my vc commodore.....its a red 2o2
and has a borgwarner 5speed in it.....tight on cash to fix five speed at the moment but can get a free m22 if it will fit..thanx wal

yes, it will fit, just need the aussie 4-speed bellhousing, tailshaft, x-member, speedo cable, clutch bits and shifter... fairly basic swap.
i had one in my torry, they're the same strenght as the m20, but 1st gear is a real low ratio...

if its the M22 i know of it should be a lot tougher than a M20/M21. I think Muchie(spelling?) is the maker so its one tough gearbox.

it has the bellhousing shifter clutch fork and it is a muncie.....wil get it in just not looking forward to doing it this weekend lol...ps sle nut we went down to tassie early may..first time...beutiful place me dad moved to geeveston on 5 acres went to bream creek show and tahune air walk and fishing in the huon river gonna retire there in another 20years lol

just pulled 5 speed out put m22 in spline at rear is bigger if i get a 1tonner tailshaft the universals are bigger will i have to change the diff
my mate had a vr commy tail shaft the spline fits length is ok but it too has larger universal i cant bolt to diff
stuck we thought maybe change the diff with a vr one if it will fit any help appreciated ..wal

Woh there. It would be no good if you try to put the 1tonner tailshaft it will hit the floor, the Commodore are design for a 2 piece shaft.
Also the VR diff is a little to long too.

But there is a way of fixing this.
1. Try to source a VB-VK 308 tailshaft, this might have the right spline.
2. You may need to get a custom built shaft.

ill have a look at a 308 tail shaft tommorow what about if i undo the centre nut on the diff where the rear uni bolts on can i change that. as the vr tail shaft will fit the rear just needs to hold a bigger uni....thanx for your help

[wal]

[wal]

If you want to fit the M22 again you need a tailshaft for an aussie 4 speed tailshaft, The M76 5 speed uses a smaller shaft and isnt suitable and the VN V6 & later shafts have bigger universals as you found out.

The splines are different on the salisbury diff yoke to the 78 series borgwarner diffs so you wont be able to change diff yokes/flanges.

I nearly put a M22 rock cruncher in my VK once but I got a good buy an an M20 instead. Is your M22 a Short or wide ratio box?

cheers

wide ratio me mate said ill prepare it incase the five speed dont last everthing anyone has to say about em being weak dont sound good its onlly behind a red 202 should b ok........thanx for yor help
