95 Lexus ES 300 check engine light is on and the overdrive off light is flashing
In my 95 Lexus ES 300, the check engine light came on and the overdrive off light started flashing, the car did not have enough power to accelerate from a complete stop because the transmission will not shift to second gear until after a long delay.
After hooking it to the diagnostic machine my mechanic told me the solenoid shifter needs to be replaced, and it could be that the solenoid shifter has damaged the car computer, so after getting the solenoid shifter replaced, the car drove fine for a while but then the check engine light came on and the overdrive off light started flashing again. The car still has the same symptoms; the only good thing is that the transmission is now a bit faster to shift to second gear. A different mechanic told me that maybe I do not have to replace the car computer and just replace the two knock sensors, I got the knock sensors replaced but that did not help, my check engine light and overdrive off light are still on and the car does not have enough power to accelerate from a complete stop, after driving it for a while. Any ideas what the problem might be? Do I really have to replace the car computer?

Chances are you don't have to replace the computer. the reason i tell you this is because you did not mention that the car is running lousy. no complaints of rough idle or missfire or hard starting. chances are that your engine speed sensor which sends the signal to the computer which then controls the transmission is most likely the culprit.. and it could just bhe that there is a loose connection between the two. if that is ok then your transmission control module is faulty. this is not the main computer, but the gobetween the trans and the ecm.. hope this helps please rate this...thanks(btw....the knock sensors control timing not the trans mission)
