I was not referring to MT90. He (ResidentWarui) stated he used 75W90 Redline Gear Oil. There is a difference.
Sorry I did not clarify which Redline 75W90 I was referring to.
Here:
THIS ONE IS BAD FOR NISSAN SYNCHROS (hard shifts, etc.)
75W90 Gear Oil - the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.
THIS IS THE CORRECT 75W90 TO USE
MT 90 - Manual Transmission/Transaxle Lubricant. A 75W90 GL-4 gear oil which is designed for manual transmissions which require 75W90, or 90 GL-4 gear oils or motor oils. Uses the same chemistry as MTL , but is a 90 WT in order to satisfy certain manufacturers which recommend SAE 90 GL-4 gear oils.
