Grinding Noise from my 2005 Grand Cherokee
I'm new to this forum so I'd just like to introduce myself first. I'm not sure if that's the thing to do or not, but hey. I'm gonna. My name is Christopher, I've had my WK for a little over a year now. She's a beautiful black beast, appropriately named Black Betty and hopefully I'll be able to share every modification I make to her with everyone here.
So now that that's out of the way, here is my dilemma. I've got this grinding noise coming from what seems to me like the transmission area. I've tried to record it and the only spot that gets the best ans loudest sound is on either side of the cup holders closest to the floor. I have an 05 Grand Cherokee 4x4 V6 with just under 155 on the odometer. I'll try to attach a video of it for you to here. But I've noticed that it's a high-pitched grinding noise that only happens when I am a pressing on the gas. It happens whether I am moving or not. It seems to go away until the next gear and it mainly occurs in all gears up until the 3rd. It doesn't get slower or faster depending on the speed, nor does it get louder or softer. I've recently had my transmission fluid checked and it's apparently on the up and up. I had my transmission 'rebuilt' shortly after getting my Jeep and if you have ever been to the place that I got it done at and met the people there you would understand the need for quotations around the word rebuilt. They're uber sketchy. The kind of business that is no longer there after you go the first time. But I digress. I've recently gotten two engine codes as well; the first one being a P0700 and the second a U0404. For the P0700 I know that it has to do with the Transmission Control System and the U0404 is Invalid Data Received from Gear Shift Control Module "A".
I tried to provide as much information as I thought would be relevant to the situation, so if there is anything else that I should be looking for, let me know and I will provide an answer to help with diagnostics.
