I got a Automatic trans. 04 Sentra and it's been making a grinding noise (sounds like when a car sits for months and has rust
on rotors). Mainly I hear it the first 30 mins (off a cold start) of steady driving till it gets really warmed up, and noise fades away I guess
that I can hear. I hear it more at the beginning of each shift. If I have to press the gas a little to gain some speed i hear it but if
I press the gas just to have the car coast at the same speed, I don’t really hear it much in the first 30 mins off cold start. And it’s
heard just when I press the gas while driving. I think I am hearing a little of it at cold starts idling or even revving the engine then
but its much more noticeable while driving till car gets really warmed up.
I also got a P1111 code (Pending code, there’s no engine light)
just looking to see if this could be related to each other? And what to look for in the grinding noise and the pending P1111 code?
I got a recording of me driving about 20 mph and stepping on and off the gas.
