On my zx2, We have L, D, OD. (auto). In L at WOT, it will shift from 1rst at 6100, and go to second and will NOT shift out of 2nd. On my auto focus, in 1rst, I was able to hold it in first till the rev limiter. Basicly, what im asking, is, can I make it stay in 1rst without a costly procedure...maybe like a switch or just a new shifter?
