Anyone use the penzoil syncromesh? Its about $5 compared to GM’s $16 a quart and they swear it meets warantee and performance requirements as GM 12345349 part number but its not the same fluid. Anyone had any good luck with it? ---

stinkromesh is the bomb. The royal purple stuff is very slick stuff, so if your syncros dont like life now, dont use the royal purple stuff they will take alot longer to speed match for a smooth shift. My VW trans syncros are shitty and dont slow down very good at all, so I like running the heavery syncromesh stuff for slightly smoother shifts. When i tried royal purple in it they ground like a mother fucker becasue the friction for the syncro surfaces just wasnt there to allow them to slow down and match speeds. ---

I’ve always had great luck with the gm shit in hondas. I tried the penzoil shit in the cobra and it seemed fine. Id bet penzoil makes the shit for gm. Do you really think gm makes its own fluid? ---
