Changed the transmission 2 times and still the same results the car will not come out of first gear and the trac light stays on someone please help me
Traction assist is a measurement that compares the spin of one wheel to the spin of another. When a traction light is on, it means that the system is activated to make the two wheels spin at the same rate.
Traction control systems perform this in several ways. Some systems use independent braking to apply the brakes to the fastest spinning wheel. Other systems affect the engine so RPM is lowered and a combination of both methods may be used to brake one wheel while reducing engine RPM.
Now the spin counter can be mounted at each wheel or in the differential. Those that are mounted in the wheels are subject to debris like rust or brake pad material blocking the spin counters.
I can imagine the trans being tied into the traction system by limiting the trans from shifting into higher gears if the car thinks the wheels are already turning too fast.
Now I am not a Lexus Expert, but on Mercury systems the Traction Control has an on/off switch. If you go to alldatadiy.com or Autozone.com and register your vehicle for free. You will be able to get wiring and fusebox details. If the traction control system has its own fuse, pull it.
There is a good chance that with the traction control shut off, the car will shift normally. Then you can drive somewhere that can test the traction control and predict what is wrong.
