2018 F-150 10-Speed Transmission Shifting Rough - Is this normal?

0

James R. · rep 0 · May 22, 2:30 AM · 1 replies · solved · Question

Hey everyone, I've got a 2018 Ford F-150 Lariat with the 3.5L EcoBoost and the 10-speed transmission. Lately, I've noticed some really harsh shifts, especially between 3rd and 5th gear, and sometimes it feels like it hesitates before downshifting. It's got about 75,000 miles on it.

Is this a common issue with these transmissions? I've heard some chatter online about the 10R80, but I'm not sure if what I'm experiencing is normal 'character' or a sign of a bigger problem. It's making me a bit nervous about long-term reliability.

Has anyone else dealt with this? Any TSBs or known fixes I should be aware of before I take it to the dealer? Just trying to get some insight before I spend a fortune on diagnostics.
