Hello every body
I need help. my 2007 g35 S sedan 5AT is stuck in 4th gear, and engine light, transmission, slip, cruise are on. Have anyone experience a problem like this? can anyone please help me. different mechanic had me change lot of parts n the car but yet nothing seen to work.I Need help please.
Thanks

 

1) what codes is it giving you?
2) what parts did your mechanic change?
3) was anything done to your car before the issue started?
4) how many miles are on your car and has it had a trans fluid change?

 

The code is saying the speed sensor and throttle sensor. I have changed both of the throttle body, engine harness, ECU, TCM and the accelerator pedal. The car has 148000 miles. I bought it from the auction with 145000 miles however I haven't changed the transmission oil yet. I don't have anymore to my mechanic coz they had me change all this part yet haven't solve the problem yet.
