Hey friends I'm new to the toyota world and I'm trying to seek some advice. I currently own a 1980 toyota pickup with a 20r engine and a 4 speed L43 transmission. My 2nd gear grinds real bad before it grabs and I've been doing some research on just swapping a 5 speed into it. What would you guys recommend as far as a direct bolt on? I'm not sure what transmissions will work best or really where to start so I thought I'd start here. Thanks any advice or recommendations are greatly appreciated.
