Mt90 compatibility with other mt fluid

Can I mix redline mt90 with the amsoil manual transmission and gear lube 75w90 both are gl4 i only have 2 quarts redline so I bought a bottle of the amsoil to make up what I needed
Hope this hasn't already been addressed at infinitum

 

I would not mix oils. Why don’t you get same MT90 GL-4 for your manual transmission?

 

These are the 2 manual transmission fluids they are also transaxle gear fluids so not differential gear lube I don't think. But i posted pics

 

Never mix oils …

• Mixing different transmission fluid brands can lead to chemical incompatibility, potentially harming the transmission system.

 

Already drained and filled with 2.6 qts. Of the amsoil manual transmission fluid shown in pic gl-4 didn't even run it just drained and ate the
90 $

Of course they’re compatible.
