Clutch and transmission fluid

Jsolo

This is what I put in - Red Line Synthetic Oil - Gear Oil for Manual Transmissions - MT-85 75W85 GL-4 Gear Oil

I'm really not sure what the issue was or what caused it to perform so poorly in the cold after so few miles. I suppose I could of put in the same fill again and it'd be fine in the winter for a certain amount of time/miles. I just chose to go back to OE. It's not great, but it works year round

They make a lot of claims, but none of them address longevity of the fluid. I suppose when used for track or HPDE purposes one changes fluid often so it's a non issue.

75W90 trans fluid is not recommended for cold environments. It will shift poorly until the fluid warms up. 75W85 is what you want to run. I'm not looking forward to winter, but do expect the nissan oe stuff to work ok in the cold.
