Every 2-3 weeks, when I start up my truck and drive away it makes a horrible grinding noise on acceleration. I’ll take my foot off the gas and. It stops, but then I step on the gas again and it grinds. Once I either hit a certain speed and it shifts out, or I get half way down the block and it shifts out, it stops and that’s it. Ford can’t duplicate the problem since it happens so rarely, it it is happening enough that it will cause damage if it isn’t fixed. No codes pop- please help.
I managed to catch the noise on a quick video. Please take a listen.
