Hey guys, what mtf do you guys recommend? I have an 88 crx si , im scared to use honda mtf because that stuff is so darn thin. Its not the og stuff back then . What i have now is gm synchromesh friction modified in my trans. And ive tried penzoil but it was so notchy and grinds. Gm synchromesh is good but still feels a little notchy. Is our trans notchy by nature? In the manual they state using 10w30 or 10w40 temporarily but the one sold in stores nowadays i dont trust them in my trans. What do you guys recommend? Thank you so much!
