this is a problem that the dealer is unable to figure out after multiple tries.
once the car is warmed up, after 10 mins of highway driving between 65mph to 75mph, only in 5th or 6th gear, the car will feel slight jerkiness (as if someone is modulating the clutch on/off) then wrench sign comes on, at full stop then "hill start assist not available".
this issue started happening at the 3rd year of the ownership, no issues on 4th gear and below, only 5th and 6th, more frequent on 5th than 6th. and it doesn't happen at colder temps, only when everything is warmed up and only happens at constant highway speeds.
been tracking the car often, but on track i don't use 5th. changes my ATF yearly so it is mostly clean, no signs of metal when changing ATF.
Dealer replaced the clutch sensor, didn't help one bit.
any ideas of what could be the issue? this is super rare.
car is 16 GT350 tech pack no cooler on transmission.
Thanks
