Buddy of mine has a 2019 F-150 w/Eco-Boost 3.5ltr engine and 10 spd trans that is beginning to give him fits. Shaking, binding, sluggish action more frequently than in the past. Engine oil changes every 5K, transmission oil and filter Bi-annually with both services performed at the local Ford dealer. He asked me to look at it and I've read enough, and know enough people with this transmission and it's characteristics to know what he's in for. There are product redesigns, software revisions, driver adaptability algorithms updates, (software) and Ford is involved in class action lawsuits over this transmission. Here is a small blurb I found on the internet that explains just a few flaws folks are experiencing with this transmission series:

Same tranny as GM but the valve bodies are different, both have issues with valve bodies. Next Gen Drivetrain makes kits and rebuilt valve bodies. ------------- 2-8050 1-7080 6080 D-19 modelE & A 7040 R50 |

would that be the same 10 speed that was developed in conjunction with GM (allegedly)? The same 10 speed that GM was marketing under the Allison trademark that Allison is now taking legal action against GM for?
well, I see NG beat me to it by 50 seconds!

| It is the same basic trans as the gm. They are junk. Being run in school buses as well and failing with less than 10k on them. |

| Sad part is we have the tech, material, and brain power to produce a tranny that would take on all comers, fit many applications and live a long life. Just no money in it. |
