I realized that those are not serious troubles specially that the transmission has no problems inside the city where I never go above 160Km/h for more than several minutes.
But, what is the failure that may confuse the TCU after over than one our driving on 180Km/h?
I suspect about the TSS (turbine speed sensor), that may send illegal information that fails helping the application regulation of the torque converter lock-up clutch!!!
My car is customized with 18" rim, and 180Km/h means 198Km/h actual speed which should be the maximum speed for the car torque, do you think the 18" rim is considered in this situation?
