75W-90 gear oil is too light and can be used in the diffs only! The stock "chaincase" lube is 80W-140. The 140 number is of most importance.
I'm currently running Mobil-1 75W-140 in my tranny with some additional EP and friction modifier (not the limited slip stuff) additive of my own specification (my company makes electric motors and gearboxes for spacecraft applications where lubrication is of paramount importance and has to work down to cryogenic temperatures).
The Mobil-1 75W-140 IMHO is fine as is for use in the tranny and is available at both Pep-Boys and Autozone for about $18/quart (one quart is enough for two changes). If you can find it, the Redline synthetic 75W-140 may even be a better choice (but not their "lightweight" stuff) since I know it uses a truly synthetic group-V base oil (the short scoop is that group-V oils are the best available). Shaeffer oils also have a good reputation, but I don't know whether it's available in a xxW-140 weight. I never used Shaeffer personally.
Just as a side note, non-synthetic, dino-oil, group-III oils can be legally marketed as synthetic even though they're not. Mobil-1 lost their lawsuit against Castrol Syntec which wasn't true synthetic, just dino oil that functioned virtually as well as the synthetics commonly available at the time.
I don't know what the 75W-140 Mobil-1 uses as a base oil, but suspect it's group-IV or group-V based on the fact that the 75W-140 is twice the price as the Mobil-1 75W-90.
As far as Royal Purple is concerned, don't get me started. My opinion is that RP is over-rated, overpriced stuff. You can do better.
I need to say this, though... What I'm saying here is to the best of my knowledge technically accurate and doesn't put your tranny at risk. Can-Am (or the dopey service manager with zero lubrication acumen) may disagree if you run into a problem and ask why you didn't run XP-S chanicase lube as specifiied.
