I heard you can purchase syncro mesh at a GM dealer. I heard that when your car starts acting hesitant to go into gear, it's because the syncros are going bad. Supposedly by adding in syncro mesh it prolongs your syncros there for keeping your tranny from grinding a little longer. Not really sure but my tranny is kinda acting funny and it's not grinding yet but i've heard rumors of syncro mesh and i just want to know if any one has used it and what was the out come. LMk plz and thanks
