Nicely designed but needs better welds
Haven’t installed it yet so idk how good it’ll fit with the 4l80, looks nicely built but it needs better weldsThe weld on the part where the transmission mount goes is pretty bad, I’m going to test fit it, if everything fits perfect, I will grind off the existing weld and put a better weld on there
