Why is my manual car over revving?
If your vehicle has a faulty TCM, then it cannot communicate properly to the solenoid, which will cause erratic shifting and high revs. Some TCM problems arise from bent pins or excess corrosion around the pinout. Other components may be failing.
Why is my car revving high when accelerating manual transmission?
