So I'm really new to RRE and been trying to learn heel n toe while waiting for my SHH Newt shifter to come in, won't be here for another month. So right now, I'm using a T150 with T3PA pedals and using paddles with clutch on older cars, and turned on h-pattern shifting so it wouldn't auto blip for me on downshifts, but no matter how slow or fast I shift on any old cars, I just get a loud grinding from the transmission. Is it because I'm not using an H-pattern shifter, or is it just my shifting ability? Thanks.
