Hello, I have a problem with Bugatti Chiron transmission system. When i switch gearbox to higher gears (much more resistance when i try to roll vehicle on whells) engine dont work smooth, with linear progres of pistons, but instead, pistons work look more "impulsish", in addition, i see efect of storage energy in gearbox (maybe twisted shafts) and in clutch gear (white one). On small distanses of rolling, engine working even after I stop a car (energy from twisted shafts and clutch gear was relesed), but on longer distanses clutch gear start sliding, what means i have to high torque on shafts. Problem occure only if drive system is in drive position, on neutral (no transmission of torque to engine) i dont see any problems. In addition, i check gearbox ratio on every gear, and from my measurments, on every next gear i have higher output ratio (cycle of 8 gears in loop). Do you have any idea? I dont feel any resistance on engine when i try to spin its using small black gear on front of it.
