I recently developed a part throttle late shift problem 1-2 and/or 2-3. If I speed up, it will shift. I was advised to see if a spring fell off the governor (based on my habit of flooring it and immediately stepping off the gas...no rev limiter installed). I am supposed to have 2 springs, but I only have one on there. I cant find the spring (not in pan and screened the fluid). Where can I buy this spring? I'll buy the whole governor if I need to.
