Chevron recalls 50wt trans fluid.

Ok so Chevron never e-mailed me back. Maybe my question was stupid idk but I guess they don't care about the little guy.
Anyhow, I found out that Eaton has a new spec for trans fluid called ps-386. It's supposed to be a more fuel efficient oil 1.5% better and backwards compatible. The old SAE 50 was ps164rev7 spec.
As of January 2017 all trans oil approved by Eaton has to carry the new spec. It looks like some oil manufactures call it a 40 or 50 while Chevron calls it a 75w90.
If it helps anyone...
