Hello my name is Egi
Come from Austria
My car is a C7 2014 with a 6L80e Atomatic.
Tuned engine LT1 Strocker 440 ci, 700Nm, 650 HP
Differential exchanged from 2.73 to 3.42
My problem.
in 5th gear the car only turns 5500 RPM and runs 150mph then it is like a limiter.
cannot be shifted into 6th gear either
Can it be related to the differential, the shift speeds, RPM or has the automatic transmission installed a limider?
Thanks
