Vxr boxs are very rare. An omega one wont fit.

Your best bet is to either email a member called "raving" or contact gmperformance parts.

The americans are reluctant to sell me one

Bought private or dealer ?

If dealer, the dealer is going to have some responsibilities here.

And under what driving conditions ? They dont just randomy go bang cruising along the motorway.

I think Monkfish do rebuilds on gearboxes. It might just be a dropped shift fork pad

Its a good club

I dont think that gearbox would work as the op has a 2005 vxr, so i would assume ls2 which would mean M12 ratio or 2.97 first gear.

Richard im not trying to say that it wont work, the 6ltr bit threw me abit, but i know most people with ros say that the m12 ratio t56 is loads better than a mm6 ratio t56.

I know that the m12 t56 is also suppose to be a nicer t56 to use due to the double/triple cone synchros.

I wasnt arguing to trying to be awkard ringram, i was just trying to explain the difference between the early and the later monaro t56's

Neither was I being difficult mate, the CAPS are because I was quoting the site (copy and paste). I thought you may have missed the text.

Im sure it will bolt right in, whether the ratios are different enough to mean its a bad idea who knows.
Im pretty sure Granada said he had to buy the M12 specially as the UK monaro's usually had different ratio's, which suggests maybe most ran the MM6 anyway. Depends what a fix/repair is going to cost in comparison. Yours was pretty trashed.

Vxrguy mine went bang drag racing, i think it was playing up before hand though.

When i eventually got it apart i had broke 3 bearings, 2 shafts and 4 gears.

My car wouldnt move and i was locked in gear, if it still drives then it should be rebuildable. Monkfish do rebuilds, if your good with a set of spanners you can do it yourself.

The M12 t56 is what the americans got in all the gtos as the ratios suit the car alot better.
