Just wondering if a 4 speed auto box out of a 240 would fit into a 264, I assume the bell housing would be different and possibly the torque converter. Just a thought because I saw the 240 wagon being wrecked on Ebay (see below) and it is fitted with a 4 speed?

Short Answer, yes.
Long answer. Requires finessing. AW41...
@Angus242164 @volvodriverman et al... It is what I am about to do with my 264 but using a later V6/auto combo...
Stay tuned...

It is possible to fit an AW71 to a 260, my father did this conversion to an '77 265 he had many moons ago.
You need an AW71 from a 760GLE*, which is a direct bolt on, in terms of bellhousing and torque converter. The AW70 from a 240 has the wrong bellhousing and torque converter, and isn't as strong.
Issues he had to overcome:
Tailshaft: He found that by fitting the front half of a 164 tailshaft to the original 260 rear section, it all lined up. I'm not sure if it was a manual or auto 164 shaft.
Speedo drive and trans mount: The 760 trans has no speedo drive, and the mount is totally different in design. He found that the extension housing from the 260's original trans was a bolt on fix for this, it has a hole for the speedo drive gear, and the original 260 mount bolts up to it.
Crossmember: It had to be moved to the most rearward set of holes in the chassis, where it was close to lining up with the mount on the trans, but in this position it was too close to the trans pan, so he had to cut sections out of it with an angle grinder to give enough clearance from the pan. I think some custom work was also needed to make the mount line up with it. An annoying result of this was the need to remove the crossmember to get the pan off to service the auto.
Exhaust: The twin pipes had to be cut alongside the trans and peices welded in, to move the "Y" section back behind the longer trans, obviously a section of the same length had to be removed from the single pipe behind the "Y" section.
Shifter and linkage: The shifter from any '83 or later 240 is a direct fit, and has the button and wiring for the OD built in. He had to cut the linkage and weld a piece of rod in to lengthen it.
*My memory is hazy, but I think 265's from '83-'85 had the AW71 trans from factory, so you can source a complete bolt in setup from one of those, if I'm correct.
Good luck finding one, they were one of the worlds most expensive station wagons at the time, not many were sold in Australia, and not many survive today.

Thanks for that very detailed response, I'll will pass on the auto upgrade, maybe a manual option would be better :-S

T5 , 5speed?

Not sure, torn between the desire to keep an orginal car 'original' and the want of having a nice lowered 264, 4 or 5 speed with nice alloys and tinted windows. It will be on historic rego anyway so maybe the former?

I have the view that unless its a very low mileage perfect example its open slather. I want my car to have the best brakes and other modifications that make it easier and fun to drive . With the 245 wagon I had the dash was going to be replaced with an E34 BMW one as it fits in and let's me put in guages and a stereo I want and looks good.
Even more so on club plates , you are able to do most anything you want as long as the safety officer doesn't mind! So thats me , others would have had seizures if they saw my car , that's for another time tho as she has been sold.

A small number of 264's around 1980 had an M46 (4 speed manual with electric overdrive) fitted from new, if you can find one then this is a complete bolt in setup, the only issue you might run into is finding a new clutch kit and master/slave cylinder rebuild kits at reasonable prices. There was a manual 264 for sale in Melbourne recently, not sure if it's still on the market.
Anything else is going to require significant custom work, so if you're going to go to that amount of effort, you may as well use something that's strong with lots of aftermarket support, such as a T5. Converting to something like a T5 is going to make an AW71 conversion look like a walk in the park.
Even when using a commonly available gearbox, you're still going to need to track down some rare parts, such as a manual 264 flywheel.

I have a 265GLE in bits here. It would probably have everything you need for a AW71 conversion.

My wife won't drive a manual so as much as I'd like one I think the auto is the best option. My primary goal now is to get the car home and enjoy it for a bit before I start tampering.
This is all good planning though, so if I happen to find a 760 being wrecked I may just grab the bit needed to do the change over. I assume the extra gear makes a big difference to economy drive ability? My last 264 (1980 Californian) liked a drink.

I'm at a loss regarding the term AW71, I assume this is a 4 speed auto box? And can I also assume the 260 wagon trans would fit straight in? Perhaps the tail shaft might be different & then the wiring for the o/d switch? If the o/d isn't wired up does it just run as a straight 4speed? What would the conversion cost?
Rob
Yes. AW71 is the 4 spd auto gearbox.
I also assume that everything would bolt straight in but Angus would know better. I think the wagon tailshaft front half and the sedan rear half would come together and fit perfectly.
Not wiring up the O/D switch would either prevent it from selecting 4th or prevent the driver from being able to lock it out of 4th, not sure which one but wiring it up would be easy.
On top of the mechanical components the cost of the swap would be minimal..

The AW71 is a 3 speed auto with an electrically controlled overdrive gear, it's not a straight four speed, but it does the same thing.
Assuming that 265 does have an AW71 (easy to check, just see if it has the button on the side of the shifter), then it'll all be a direct bolt in. The tailshaft is the same, fitting the wiring harness is easy. I think you can buy a blanking plate from IPD with a bypass passage in it, which goes in place of the OD solenoid on the trans, which means that it's always in OD when in 3rd gear, but means no wiring or button is required.

If you mostly drive around town, you're unlikely to notice a change in fuel economy, as the trans won't be spending a lot of time in OD. If you do a lot of highway driving then it should use less fuel, as it'll be in OD on the highway and revs will be lower. I don't think you can expect stunning fuel economy from a 35 year old V6 regardless.
beema41
Probably not expecting stunning fuel economy but Canberra has a lot of 80 zones and a few 100's and of course heaps of roundabouts, but not expecting anything spectacular, really just trying to save the engine revs. My old 164 would go down the Tuggeranong Parkway (100k zone) screaming it's head off with the old 3 speed.
Tigabu
I have found the 3-speed(BW35)/V6 Combo is actually pretty bloody good on fuel, considering its age etc, so I would think that a 4-speed in situ would be even better. Launceston is about the size of Canberra but even hiller... :)>-
beema41
I will get the car home first and get it running properly before I even think about playing with engine/trans combo but good to throw it out there to see what the concensus is :-/
Tigabu
Aye...
