I recently got some mud in my rear cvt intake. No funny sounds but i knew there was mud in my cvt but it shifted fine. so i removed the cover washed all the dirt out belt looked fine i didn’t take anything apart inside. Got it all back together and now its giving me a hard time trying to put it into the different gears. Especially high to low. even when i forced it to low the wheeler stayed in high. Any advice? Should i take it somewhere to have it professionally cleaned? Thanks
