Hey guys, I can usually find what i need on here w/o bothering anyone, but I'm lost on this one. 2006 F150 5.4 4x4 155,000 miles. Plugs and coil packs replaced about 6,000 miles ago. Truck now seems to be in a bind while accelerating on an incline. Overdrive on or off has no affect. Sounds feels like rumble strips, jake brake..with a deep moan and bog down occasionly. Can make it do it on command when on a hill. sometimes upon take off as well. Ford Dealer said no doubt it was the Catalytic convertrs so both replaced. Engine does idle a little smoother but has had no affect on original issue. I've read threads about Torque Converter issues, is this what I have, Am I on the verge of a Transmission replacement? ANy other options? may trade it off if I am, hate to throw good $ at bad $ .....

Did you read this thread? https://www.f150forum.com/f4/bog-dow...solved-166431/
Have you cleaned the MAF and throttle body? Changed the fuel filter? Any codes?

Thanks but yes I did the foam gasket replace this morning, helped with the moan but still something going on with drivetrain, it's like something won't lock into place, I took videos for sound but don't know how to upload them

My guess is the TCC solenoid for the torque converter. I posted about the very issue either on this forum or another one.
