Ok so i got one of those roush prepped tranny's from the GB last year, still havn't installed (along with the 3l block in my garage)

but anyways:
to those of you who got one and installed it;
1) did you upgrade any of the components inside b4 u installed?
2) how does the torsen diff seem to work with it?
3) which fluid did you opt to put into the tranny?
Just purchasing a few more parts b4 i dive into this massive rebuild in the summer
