Thanks all, will post back here once they call me on their diagnosis.
The shifts are smooth, just the grinding noise and the strange throttle hesitation.Is it hard to shift at all, or just the grinding noise?
I would be raising hell at the service counter and my voice would be heard throughout the dealership. I would also be talking to the GM about refunding all the labor charges on that repair. They had you spend all that $ and they didn't even diagnose the issue properly before telling you that was the fix. Then to add insult to injury they tried to brush it off by not telling you that the problem wasn't fixed or not even testing it to see if their "repair" fixed it. That's complete bs and this is exactly why no one trusts shops and especially dealers to work on their cars. Call the Ford 800 # if they don't cooperate and I'd call your bank to dispute the labor charges since you were deceived.
Hello and thanks for the informative feedback. I don't hear any additional sounds and will share this info with the dealership in hopes of finding a resolution.I'm wondering why the engine would only make a grinding sound during a shift after light acceleration and then give a throttle hesitation if it were a bearing. That doesn't sound right to me. Chassis ears should be used to track down the basic location of the sound. All dealers have them.
Are there any other noises that you ever hear?
The 3V is notorious for the original timing parts failing. Maybe after letting off the throttle to shift gears the oil pressure drops and makes the chain go slack for a second. The original chain tensioners tend to blow out the gaskets and the oil pressure drops in the system. The timing system is dependent on oil pressure to function properly. If the chain is grinding into the guides or the timing cover then you would hear a grinding sound. It could also give throttle hesitation if and when that were happening.
Thank you so much and will also share this with the dealership mechanics.Worn thrust washer on the crank? The tranny input shaft pushing into the crank. Should be easy enough to check using the method FordTechMakuloco used to check for excessive thrust clearance. Just a thought.
Unfortunately I do not, the vehicle has been at the dealership since January 11th and even if I could , not sure my phone would actually pick up the noise over the exhaust.Do you have a video of the noise to share?
