Default Transmission gear ratios ??? Anybody know what they are???

I have been doing some reading in regards to doing a rear end swap and I would like to know the transmission gear ratios so I can figure out what final drive will be best suited for my needs (and yours too). Maybe one of you might work in a dealership and could look at a factory service manual and post the gear ratios for the GS400 and GS430 transmissions.

There are some good online gear ratio calculators to use so we can find our optimum ratio for our application. This is my favorite to use .... http://www.f-body.org/gears/

TIA

Stock GS4xx rears are 3.26. A lot of people here swap them out for the 3.76 rears (Supra TT, RMM Etc.) for better launches and acceleration.

The final drive gear ratios are a given, there are plenty of write ups on what car have what rear end gears. What I am after is the TRANSMISSION gear ratios.

all GS300/400/430 uses the same A650E transmission.

I got the info from the Lexus official press I printed out awhile ago.
