I have a really nice 2010 lariat, that is in like new condition and I don’t want to have to trade it in but it’s got a issue with it and it’s driving me crazy. I have taken the truck to 2 ford dealerships to repair it, so far they have put some kind of stuff in the motor and in the transmission, it didn’t seem to help it so I took it to a higher rated dealership and they changed out the torque converter which didn’t fix it either. The symptoms are number (1) when you crank it up the idle is really rough running for a minute or so then it calms down, symptom (2) is when you are normal driving and easing the gas down at cruising speed a hum, low roar, very slight vibration you can feel in the gas pedal comes and goes, it seems like it can do it through the different gears, but at the same torque range. It seems to still shift like it’s supposed to and if you give it more gas it doesn’t seem to do it, or seems to mostly skip over the torque amount that it would do it and if you aren’t giving it any gas it doesn’t seem to do it. It seems to do it giving it about 1/6 throttle just easing going down the road and you’ll hear it/ feel it for 20-30 seconds then doing nothing different it’ll stop for 20-30 seconds, then back again. I’m thinking it might be something going on with the transmission since the torque converter didn’t fix it. Any ideas what that might could be? Thanks

Also I forgot to mention that with the 4 wheeler loaded on it climbing large hills it was slipping some, I haven’t driven it loaded since they replaced the torque converter so I don’t know if that helped the slipping or not.
