I made a similar post over on the RZR 170 specific forum a few weeks ago, but I’m hoping this forum can provide additional insight. Here’s what’s going on:

When you first put it in drive, and press on the gas it will engage harshly (slams into gear instead of clicking into gear). It won’t do this again until taken out of gear.

If you press on the gas very lightly when you first put it in drive it will engage much less severely.

No grinding or issues otherwise.

No additional issues with the machine once it’s in drive and engaged.

Thanks for your help! I’m hoping to open the machine up this weekend and your input will help me a lot.
