I am using Redline MT-90 for the trans. It's a 75W90 weight.

There seems to be lots of questions because of the GL-3 recommendation by Polaris. I called and talked to them. It was eye opening.
- Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified
1,3,4 GL applications can use the same fluids to a point. It's when you jump to GL-5 or a product you can use GL-5 in because it contains reactive sulfers
- Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
- Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
- Eliminates notchy shifting, even when cold
For the angle drive I am going to use Mobile 1
