I think that using a complete drivetrain from engine to transfercase from a doner vehicle and all the stock electronics is a lot "easier" than taking a transmission that was never meant to be bolted to one engine, figuring out and building the adapter, torque converter, and electronics.

And the only reason I say that is his setup was already put together by Toyota and everything was known to work. We are trying to find a way to put parts together Toyota never intended to mate.

So this guy built a 40 using a 2UZ V8 plus A750 5 speed tranny and we are still pissing in our pants here about getting the 5-speed tranny to work in our trucks.

My UZJ40 Build - 2UZ iForce V8 and a750f 5spd auto

@scottryana what do you think?
 
Slee is asking for $25K to swap in the 2UZ using the A343 tranny, because as he stated the A750 will not work on our 80 due to electronic traction control and who knows what other gremlins.

This guy above got a 2UZ engine to work with an A750 tranny in a 40. No electronics problem there.
OK, the bolt pattern matches perfectly, since it was built that way.

On page 9 of this thread, we concluded A750 would not fit our application due to physical differences. So I moved on to a different obsession.
 
@scottryana I would like to revisit an old hypothesis regarding the A750. Gotta get this one completely out of my system.

If the early 2UZ came with A343 and later with A750, what exactly changed over the years?
Was it the bell housing on the A343 that was different than ours so it could be attached to the V8, or was the bolt pattern totally different on the early 2UZ engine to be able to work with the A343 and then later the design was altered to accommodate the new tranny (A750)?
 
It was the Bellhousing. The 2UZ bell housing fits the A343, and the 2UZ. On the later trucks it fits the 2UZ and the A750. On our trucks the Bellhousing fits the 1FZ and the A343. All 3 are different parts and you can't mix and match them. None of the 2UZ housings will bolt to the 1FZ and the 1FZ housing will not bolt to the A750 as proof of this thread.

I was hoping the Bolt holes on the A343 and A750 would have been the same but unfortunately they were not. So you would have to use a 1FZ to A343 bell housing and make an adapter to the A750. And likely a custom torque converter to take up the space from the adapter.

Haha, it looks like those bell housings are about $2000, not including paying them to R&D the first one. Add the transmission, and the compushift and you are looking, at a $4000+ swap....

group buy?

More than half way to a DIY LS swap with GM transmission at that price.

Best option for a Toyota auto 5-speed is the A750 with a 2UZ attached to it. Found some dirt cheap ones on Ebay.
 
Got a reply today from down under regarding a train conversion.

I cannot justify the effort in any way.


"Certainly its possible , but very costly.



I don’t know what your budget is like so I have included 2 different options below where I hope that one will suit you perfectly. I have also attached our 4 page brochure.

Most notable pros of this transmission:

  • Excellent gear ratio spread
  • Low 1st gear for standing start acceleration, downhill engine braking and off road.
  • Excellent torque multiplication from the diesel torque convertor “Will certainly bring the 1HZ alive”.
  • Compact 3 dimensional size.
  • Zero loss of engine power on manual – automatic conversion +/– 1%.
  • Able to withstand high HP and torque ratings
  • Very high OEM towing capacity.
  • Greatly Improves 0-60Mph times
  • Cable controlled T.bar assembly “Requires only very small hole for cable to pass through, so well suited to Armouring”.
  • Tip Tronic T.bar assembly for ease of use over a broad range of different driving styles “ in short idiot proof”.
  • Overrunning shift design meaning 1st through to 4th gear there are no clutch disengagement never leaving the transmission in a moment of apply/release. 4th – 5th is the only clutch to clutch shift.
  • I have attached a dyno sheet below that shows the transmission capabilities"
 
Any measurements on the A650?


I think we got the 5 speed auto all figured out though.

ATI adapter for 1FZ-FE to a GM style tranny (4L80 which is the same as TCI 6X --- 6 speed) ~$1500
ATI Transmission Adapter Kits

TCI 6X. 6-speed transmission $5300
6x Six-Speed GM 4L80E Automatic Transmission (850hp) - TCI® Auto

Transmission to transfer case adapter (Mark's adapter) ~$1350
50-1702 : GM 4L80E to Toyota Land Cruiser HF2A Adapter Kit | Advance Adapters

Torque converter - custom made? $200-$800???


Let's say a grand total for the parts $9000 +/- doesn't matter at this point anymore.

Given the length is correct for the adapters and transmission so not a lot of other work needs to be done to move the transfer case back, shorten the rear drive shaft and lengthen the front one. Let's just pretend that does not have to happen at all.
Let's also pretend the first gear can be shorter than 2.97 as it currently is in the TCI 6X, somewhere 3.2 - 3.5 range.

Who would be crazy enough to go through with this?
We are almost touching the V8/6Speed swap territory here.

I cannot find a good reason I should even attempt to look into it any more. (this setup at least)



So, what is our last hope?
A650 I think.
 
Anything helpful here?

That looks like the trans I put in my father's Mercedes diesel
 
Is that a trans you have access to or somthing off the Web. I have the a750f and a343f parts in my basement to compare measurements.
