Hey everyone need a little help. Got an 05 trx 450r was riding for about 30 mins then the trans kinda downshifted on its own so I stopped and put it in 1st went to accelerate and made an awful grinding noise that I could feel on the shifter. Tore apart the clutches didn’t really see anything that would really cause a grinding but ordered new clutch kit anyways. Anything I should check before installing new clutches? Oh also when I pulled out the clutch plates I could not get that pusher rod out.
