check the number of your mod and gradually increase until the problem disappears, in my case the problem was for the saturation of the FFB
I don't know if it is useful for you, but in this SCCA regulation you can find some information about the car on page 272. Gearbox is made by Hewland. I really like this mod, it would be great if you could improve it further. https://www.scca.com/downloads/45408-gcr-may-2019 http://www.hewlandclassic.com/manuals.html
