my tranny grinds second on my awd as i made a forum before about but i have a question about it before i spend 40 bucks on gm syncromesh friction modified, my second gear will only grind when it gets hot like after a 20 min drive and i flushed out the tranny fluid and put in penzoil syncromesh wich isnt friction modified and its a lil better but not that much so do you think its definatly the syncro? or maybe if i get the friction modified it will help?im soo lost right now i have very low money and i cant afford a 700 dollar rebuild for my tranny.....maybe i am just not fit for a dsm ........need info thanks
