ZF 4HP22 auto box??

Rob

Apparently some Volvos came fitted with a ZF 4HP22, any idea which ones?

83-85 760 Turbo's, and 85 740's. They aren't really that great though and mostly removed...

Philia_Bear

some 740's and 760's got them
IIRC it was some specific models or options that got them

its a **** trans but I want to get my hands on one cause the bell housing might be adaptable to ZF

Ok.. interesting.

I assumed (for absolutely no reason at all) that it would be an ok box.

might do some more research

The aw70 is 10x the box stock

The zf has the nice habit of wearing the bands when reving above idle speed in park or neutral
thus they die quickly and easily

And yet they are fine in range rovers etc.

egads (she/her)

I am only basing this off internet research so take with a grain of salt, but it is just that the AW boxes are really really good. The ZF does seem to do well in lots of other applications where there isn't a better stock box to easily upgrade to.

Volvo did exchanges to the aw71 when new on the turbo cars. The non turbo ones survived until they die from old age.

Rob

So... does anybody have one?
