I think 75w-90 as well, it just has to be a gl-4 type fluid, the diffs take gl-5 type fluids. If you google or search YT, theres a thread on the fluids needed, i can't seem to find it to save me though.

Transmission Gear Oil - very important - our transmissions do NOT do well with the current standard GL-5 gear oils. It's too slippery and the synchros don't work, making for very hard shifting. You need a GL-4 fluid, and the one nearly every Toyota techie recommends is the Red Line MT-90 which is a synthetic 75W90 GL-4 Gear Oil:

The differentials and transfer case, however, do better with a GL-5. Red Line makes several good synthetic GL-5 oils, this is a popular one:

Here we go, found it!
