can it be done...
im looking at an XF and really want to keep the 250 but hate 3spd autos...yes i could put XG running gear in but dont really want the 4.0lt
am not going to change it to manual either so dont bother with the usual autos are crap thing (unless I cant convert to 4spd) |

Anything is possible, that is why this forum was created, just it depends on money or skills or both.  I do not remember if how different the bell housings are on the 4.0L to the 4.1, I am sure someone would have one they could take a picture of, you might need an adaptor plate and spacer to space the flex plate to towards the gearbox.
Not sure about the tranny tunnel, I have a V8 4sp auto outside and it doesn't look any bigger than an FMX from memory, FMX fits with heaps room as the tunnel is basically the same as fitted to XD-XE. I am happy to be proved wrong here  .
Nothing is going to be as simple as a pull out and bolt in no matter what you do.
You would either have to use an EA or pre EBII tranny ecu or V8 tranny ecu, you would then need to hook up a throttle position switch, speedo transducer is the same, gearbox yolk is the same but I think the 4 spd is a longer gearbox, so the tailshaft would need shortening.
Then you have to mount your new 4sp shifter.
So why do you hate the old BW auto? If you think you will kill it, you could instead bolt in a C4, as they were an option on some of the older Falcon 4.1, lower first gear and much stronger. |

4spd's dont fit - its been tryed many times with a OHC conversion, all end up 3spd auto or manual
and C4's never came out behind 6's, but c9's did (had to clarify as ive seen wrong box's purchased before!) |

| have you given it a try to see how close it goes to fitting ? it may just need some hammer action. i put a C10 onto an escort motor once. i just got the centre hole in the escy's auto bellhousing bored out. then welded on some plates so it could all be bolted together. that was 5 years ago and it's still going strong. wiring in the trans computer won't be too hard either. you would need a tps somewhere. the relevant manual would tell you what other inputs you need. andd if everything went to plan, you might even be able to use the 4.0's converter. have you considered an aod ? still get the overdrive with less hassle. |

I think you'll find they just used an E series pressing - same for the XH too. |

I cant see why the 4 speed auto would not fit the tunnel. I have a XG and 4 speed in an XE ute and the only thing that hit was the gearbox mount which has to be modified to suit the 4 speed anyway.

PS I have a C4 behind a six that was factory |

That's good to know.
I am considering a 4.0 4sp conversion to an XE wagon.
It's gotta stay auto, or believe me, it wouldn't.
And I too hate the slug-o-matic.
I did 10,000km in 3 months in an auto XF and by the end I hated it with a passion!!! |

4spd auto's do fit in everything from XR-up without enlarging the trans tunnel...even V8 ones which have a bigger bellhousing!
AND FOR THE FOUR MILLIONTH TIME THERE IS NO SUCH THING AS A f**k C9!
It's a 6 cylinder C4 for chrissake!!!!! |
