Beno were there 2 different bellhousing between the 100 series with the 343 and 750? If not why wouldn't the 343 bellhousing bolt up?

Here are some pictures of the A750F I have...
The bell housings are quite different looking between the A343F for the 2UZ and the A750F for the 2UZ. The rear extensions for the xfer are quite different looking as well.
The bell housings look different again between the A343F for the 1FZ and the A343F for the 2UZ.
That said, some money, access to a machine shop and an engineering friend could probably be useful in a project like this.

So would an A750F trans bolt up to the bell-housing pulled from the A343F FZJ80? the electronics could be circumvented in a manu-matic setup and a TC lockup switch, or the best option would be this: http://www.hgmelectronics.com/products-compushift-controllers/compushiftii
this would be awesome for someone running a standalone ECU as well which would mean one could do away with the stock ECU and TCU completely... the A750F is far more customizable as they have upgraded clutch packs & friction discs, billet converters, upgraded solenoids, VB's, etc...

No one knows that's why I started this thread. Lol. I think it would. But going to have to wait and be seen.
I talked to a guy name Mike at hgmelectronics he said the following:
Mike:
We do not have a unit for the 750 at this time. We are working now on the AB60 and may have the 750 some time after that. Check back with us from time to time.
Me:
There was some discussion that your A761 computer could control the A750. Is this possible?
Mike:
We have not done all the work on that yet, they are similar but not the same. We are sorting all that out as we go along. Stay in touch.

761 is the 6spd lexus trans isnt it?
the A750F input shafts look different there.
A person might have a chance if they could source an A750F from an early 100 that had a 1fz-fe in it as the input shaft should be the same. then it might be a simple bell housing swap or adapter plate.

Well, the AB60 is the automatic tranny from the 200 series sitting behind the 5.7L.
That transfer case is chain driven vs. the gear driven 80/100 series iteration.
The early AB60's in the LC had some electronic issues that necessitated an upgraded ECM logic as well as an updated ECU (including replacing the transmission).

100 series (with the 4.7L V8 2UZ-FE) never had a 1FZ-FE in it in the US market.
Worldwide, the 1FZ-FE only ever came with a 4speed auto A4XX/A3XX iterations.
I wonder if this standalone could be wired up: http://www.powertraincontrolsolutions.com/product/TCM2000/
Im sorry I messed that up I meant to refer to the early 100 series with the a343f transmission mated to the 2UZ
the input shafts do look different though, if one could swap the input shafts between the A750 and A343 you wouldnt have to have a custom one cut at a machine shop.

Ok I think we are all getting a little mixed up. lol.
Here is what we know with certainty.
- The A343F and A750F are dimensionally the same (probably without the bellhousing)
- The A750F never came behind the 1FZFE in any location
- The A343F came behind both the 1FZFE and 2UZFE
- The A343F used behind the 2UZFE is not specific to that engine
- There are different bellhousings used between the A343F and 2UZFE but everything else is the same (This I know because I used an 80 series A343F behind a 2UZFE)
- The input shaft on the A343F works for both the 1FZFE and 2UZFE
- The bellhousings "look" different between the A343F and A750F, we don't know if any of the bolts line up. The 6 from the 2 pics "look" like they do.
- The standalone shift controller is not ready yet for the transmission so you would be on your own if you did buy one.

Yes if you are looking to crawl, there is quite a difference between a stock 80 with 5.29:1 diff gears and an 80 with A750F, marlin and the same 5.29:1 gears.
35.5:1 for the stock 80
55.5:1 for the A750F and marlin's.
So 56% increase in crawl, err 56% decrease in speed. lol.
And you also get a higher top gear so on paper you could get better gas mileage. .716:1 vs .756:1

The A750F would be a really sweet setup and one heck of an upgrade if possible...

Yep. UZ over FZ any dayIf you are going to go through all the effort and work to change the transmission, why not just keep the 4.7 V8 on the front of it and put the extra gear to good use. Just my 2 cents
But for some looking for a relative 'simple' conversion ..this could be a hell of a lot better than the stock trans .
Im guessing here but these may be reasons KDXman
The 2UZ is more electronically complex. it doesnt appear to be as overly built as the 1FZ's bottom end, especially for turbo application. The desirability of this A750F transmission I think is that it might possibly mate with the 1FZ with our A343F bellhousing and stock transfer case. they can be found for 350-500 bucks in good working order and 1200 bucks brand new, have a lot of aftermarket support and may not actually have to "go through all the effort" as it may appear.
looks like its been brought up a few times and no one has acted on it...

With all the wiring required it almost seems simpler to swap the engine and transmission plus you get a V8 out of it in the process. Salvage 100's can be had for reasonable money at auction (https://www.iaai.com/Vehicles/Search.aspx?RefinerSetName=Vehicle+Type&RefinerName=Automobiles) and it sounds like you need a donor rig for all the electronics you would need just to swap the tranny.
When you could of had a V8
Now with that said will some one start this swap I would like to see if it works

No I think the basic operation is not that advanced. Granted you wouldn't get things like AI and flex lock up etc, but you don't have any of those things now.
But without the compushift II setup for it yet, I don't think it really matters. But once that happens, I "believe" this will be a bolt in solution. - Ryan Scott 9/15/2014. Lol.
