2020 1330 engine/trans

[mrwog]

If someone knows, would like to know if if they went to straight cut gears in the 2020 RT, inquiring mind.
I have allot of loud whining in 4th gear at 3500 rpm and same in 5th at 3000 rpm. 600 miles and no change in noise.
Working with dealer to figure this out, we rode 2 others and one had it and one did not.
BRP wants me to get 3k miles on it and change oil and see if there is a change in noise. They say they have not encountered this yet.

Good question. opcorn:

I drained the oil at 600 miles and the drain plug looked like it was a Chia pet

In every combustion engine that I have ever did the first oil change there has ALWAYS been more debris in the oil than in the subsequent changes .....this is why on any new engine I have, I always try to do the first change done by 500 mi. ..... yep it may be over-kill, but that is my reasoning .....

Straight cut gears aren't new. My 2015 has them for the camshaft drive. Why some seem noisier than others? Well, that's the mystery that needs solved.

This seems to be more gear related to trans. As I'm thinking also the dealer. {hard to tell} :dontknow: we shall see.
