Thumping / cycling noise. Continues to Cycle from any gear to neutral and back.

Thrustmaster T500 & TH8A Shifter. Continues in a consistent pattern to Cycle from any gear to neutral and back. It continues to repeat this pattern as long as I have in gear with clutch in. If I put shifter in neutral it stops. For example I have in 1st gear with clutch in. I can see the gear indicator continuously cycle to neutral then back to 1st. It continues to do this at a consistent pattern over and over. If I put shifter in neutral it stops. If I accelerate and drive the car it is ok until I come to a stop in gear with clutch in. I don't see the gear changing when racing but I hear the same pattern noise. It sounds like I am driving over expansion joints built into the highway. I've tried turning off every option except steering, pedals and gear shift assignments. I can't figure this one out. It only happens in Autobilista and no other games. Any help would be appreciated.

 

I suddenly had the same issue and couldn't get out of the pits. I would shift into 1st gear and the car would "thump and shift" back to neutral. Ultimately, I ended up changing any setting I could, restarting the game and although it stopped auto shifting back to neutral, I don't know what I did to make it stop. T300RS using Ferrari F1 wheel and paddle shifter.

I have my game set to maximum difficulty but with auto clutch and auto blip since I only have paddle shifter.
