Auto to Manual Swap

I understand how it works and is designed. I've even seen inside a few of them as well as other transmissions (T50, R154, V160, and a bunch of transaxles as well), I know people have had some issues with them in the past as well. I did a lot of research on the RA62 before buying a car equipped with it. Almost no issues that I've seen have been related to breaking anything due to power.
The AY6 transmission is installed, from the factory, in cars with similar weight and torque to the IS350, as well as trucks with significantly more weight and approximately the same torque output as the IS350. The transmission is an unconventional, lightweight design. It was clearly not designed to take abuse like other transmissions were (V160/161), but in my opinion the 2GR-FSE isn't going to break it.

Well even if the RA62 can handle the torque of the 2GR, nothing will prevent it from having the problems of the 4GR. Is the 6MT from the x-runner the same design?
There is a community of swapping T56 with the 1JZ/2Jz/1UZ out there, perhaps that would be a more reliable option for the 2GR? Bolting the auto bell housing with the T56 body on an adapter plate. More info here:

Agreed, there will still be the inherent design issues with the AY6/RA62 on any vehicle you install it on. If you REALLY wanted a manual transmission behind a 2GR, and you wanted a proven transmission, adapting another transmission is definitely the way to go.
EDIT: Yes the RA6x from the Tacoma/FJ Cruiser is essentially the same design.

There are 2 videos on there of it running as well. Read on their development blog that they seem to really enjoy driving it as well.
Hard to tell from the pics, I wonder what transmission they are running. I can't seem to find the info anywhere.

It looks like they are using the setup from the IS250 MT, just because things look so OEM. I would be very interested to know what they did to fool the TCU, but I doubt that info will be publicize just like most of their secret projects.

The BG6 is a much newer design than was used on the MR2, Celica, etc. As far as I know it has never been used in North America, though it is used in Europe, etc. Especially in Diesels (Corolla, RAV4, Avensis, etc.)
Toyota's code for the BG6 is the EA6x. I checked into it further, and it looks like the Evora uses the EA60.
The similarly designed, but medium-torque range transmission that is sold in North America is the Aisin BH6, which Toyota calls the EB6x. The 2010+ Camry and 2011 Scion tC both use this transmission.
The 6-speed manuals used in the MR2 Spyder, Celica GT-S, Corolla XRS, Matrix XRS, etc. were all much older designs, the C65M (MR2) and C60 (Celica and XRS models).

That list is not 100% correct. Note that while the Scion tC is listed under both the BG6 and BH6 columns, there is in fact only 1 type of 6-speed transmission that's ever been used in the Scion tC, the EB62 (BH6).
Every other car on the BG6 list only uses the BG6 (EA6x) outside of North America.
The Toyota C6x-series is what was used on the 1ZZ/2ZZ (MR2 Spyder, Celica GT-S, Corolla XRS, Elise, etc.).

The list IS correct...
1) the bg6 is the older design ( feb 2005) while the bh6 2008 approx.
2)i dont know where you sourced youre info but a brief google search reveals that the bg6 is infact currently being used by quite a few vehicles, ie mazda 3 , 6 ect.
3) no offense, but until proven otherwise id rather believe the OFficial source. Verifying info on the net is very arbitrary and contextual

Sorry, I was referring only to Toyotas, I'm sure the BG6 is used in North America, simply not in any Toyotas.
The list cannot be correct. There is only one type of 6-speed manual transmission in the Scion tC. There's no possible way that both the BG6 and BH6 were both used for the Scion tC.
Also, I work at Toyota, I got my info by looking it up in the parts catalogs/new features manuals. Aisin's lists don't list application information about which models used which transmissions. It doesn't say "Corolla XRS" and it's a global list, it does not apply to any specific region or country.
For example, the Avensis is not sold in North America, the last RAV4 with a manual produced for North America was the 2005 (ACA2x) model year (same transmission from 2001-2005). The Corolla Verso is not sold in North America. The only Corolla sold in North America with a 6-speed was the 2005-2006 Corolla XRS, which used the same transmission (C60) as the Celica GT-S and Matrix XRS. The C-series transmission was first used in 1983, and the first 6-speed was the C160 used on the 4A-GE in 1997. The only Camry with a 6-speed manual in North America is the 2010+ 4-cylinder (ASV40, 2AR-FE 2.5L) model with the EB62 manual transmission, and it only utilizes 2 shafts, while the EA6x (BG6) uses the 3 shaft design.
The Scion tC is a North America-only vehicle. From 2005-2010 it used the 2AZ-FE 2.4L engine with a 5-speed manual transmission (E350). The E35x transmission has been in use by Toyota since the 80's. It is quite old. The first Scion tC to use a 6-speed manual is the 2011, which borrows the 2AR-FE and EB62 transmission from the 2010+ Camry. This is the 2 shaft BH6 design.
In conclusion: Of Aisin/Toyota's "New Design" 6-speed manual transaxles (BG6/BH6/EA6x/EB6x), the only Toyota/Scion models sold in North America utilizing them are the 2010-2011 Camry 4-cylinder (EB62) and the 2011 Scion tC (EB62). The Scion tC is not sold outside of North America, and has never used a different 6-speed transmission. Both of these vehicles uses a 2 shaft design (BH6), while the 3 shaft design (BG6) is not used in any North American Toyota.
Clearly if the list is wrong regarding the one item, it can be wrong in other regards. Aisin's website is often ambiguous, and this is just another example.
PS: This doesn't really even have much to do with the thread at hand, considering all of these vehicles use transverse mounted engines and transaxles, neither of which is employed in the IS. So none of this is relevant to the actual topic of the thread, haha.

Ok.....il make this the last post cause its getting moot.
1) toyota should be a great company to work for.
2) using the toyota book isnt the best way to rearch products from an affiliate.
3) the website is correct
4) the scion tc was developed in 2004... The bh6 transmission didnt EXists back then; in toher words there has been more than one manual for this car.
