I have got this annoying problem with my gearbox, whenever I do a fast shift from second to third at high rpm (7500+), I can’t always engage it properly, it doesn’t crunch or anything but it just gets stuck in the middle and I can’t push it up to third. It used to happen like once every 10 races, but it gets more frequent now like more than half of the time I can’t shift 2-3 properly. All the other gears are perfectly fine. Any suggestions? Btw the box is a stock ITR box with ES bushings.
