Installing ZF 4HP22 transmission in MK2

Postby obrienpb@eircom.net » Mon Apr 22, 2019 8:04 pm

I'm carrying out a complete bare metal rebuild of my 1961 MK. It's currently fitted with a 4 speed Moss with O/D. I want to fit a ZF 4HP22 auto box from a XJ40 and I believe that this is quite a feasible swap which has been done before. Has anyone out there got experience of this swap? I can't find anything to help me with the conversion. Especially reworking the bell housing. I know that I'll have to widen the transmission tunnel to take the wider ZF box. And I'll probably have to modify the prop shaft. These items are not a problem. But information on mating the ZF box to the engine would be much appreciated. I plan to use the J Gate selector from the XJ40 but another gap in my knowledge is what to do about a kickdown cable.Any help would be much appreciated.

Graham Whitehouse (Classic Car transmissions) is the expert in these conversions and can probably sell you all the parts you require for a conversion. Mike.

Thanks Mike. But I was hoping not to spend the £5,000 plus which is the price of their conversion :-)

It is expensive but it is a complete kit. Just to make you jealous, about 18 months ago, an advertiser in the JEC classifieds was asking £2000 for an unused kit for XK engine cars. Mike.

I like the Moss box! Why not a good synchromesh box if you must change it?
