My LS1 came packaged with a Richmond/TexRacing T10 Transmission, Hurst shifter, and a Lakewood 15005 bellhousing. From my research this should be fairly easy to adapt to the LS1 while using the LS1 flywheel/clutch and a specially made hydraulic throw-out bearing.
First, I’ll start with some links

My gearing:
1st: 2.64:1
2nd: 1.75:1
3rd: 1.33:1
4th: 1:1
Looks like it’s a ‘W’ gearset according to the catalog linked above. My stock rear end is a 4.08 final drive, which absolutely will not work with this transmission. I have already picked up a 3.54 final drive from a 350z that should make the gearing a little better for my application. However, I’m still looking for the 3.3 from the automatic 350z.
I still haven’t decided if I’m going to use this transmission. The lack of overdrive has me concerned that it will keep me from picking this car to drive to work, like I had planned on doing. On the flip side, this transmission would save about 50 lbs over the alternative (T56), so it isn’t something that’s easy for me to overlook.
With that said, I opened it up tonight to get an idea of what the gearset looked like. Without any oil, it shifted fairly smoothly and didn’t seem to have any binds. Of course I didn’t shift it too much since it was dry of oil.
Here are the internal pictures:
