What is max tranny temp and max boost?

With a tranny temp guage, at what temperature do I need to start worrying about the 48RE tranny?

What is the max safe boost with the stock turbo?

I searched and searched, but couldn't find the answers to either.

25 psi is when the stock turbo will dump on the 03/04. I think it's 35psi on the 04.5/05 ( 325/600) engine. As far as the tranny temp I have seen mine as high as 185 when in traffic or jockying the 5VR around too much. Normally it will come down real fast once you get moving.
This data is from a 47RE and I think the 48RE is the same:D
