My 2020 Explorer ST 10 spd Transmission is shifting erratically. Rough shift when coming to a stop and when accelerating at 55 mph.(73000 miles)

Dealer says I need a new transmission. I have read about PCM UPDATE and Valvebody issues.

Any thoughts to assist in the diagnosis is needed.

Thank you.

My son’s Ford Escape transmission went “blooey” on the freeway when it had 90,000 miles on it. Fortunately, it was under warranty and he got a new tranny. A couple months ago, the replacement went “blooey,” but no warranty as he has 220,000 on the clock. A replacement with a rebuilt tranny runs around $5,000, a lot more than the car is worth. He also has a small crack on the cylinder deck between #2 and #3 cylinders leaking gases into the coolant and coolant into the oil. So his now-worthless car is sitting in the driveway and he’s riding his bike to work. What a mess.

Ford has had notorious transmission problems the past decade. We’ve had one Explorer, and two Expeditions. Explorer was good. First Expedition got a serious connecting rod slap and went to Pick & Pull at 190k.

Oldest daughter had a trouble-free Explorer in college and then bought a 2012 Escape after moving to Hawaii. Non-stop troubles with her Escape. Middle daughter also bought a 2012 Ford Escape and had a lot of transmission problems.

Ford quality used to be good. Pretty pathetic these days.

Good luck to you! Have you bought an OBDC 2 diagnostic tool? That’s where I’d start.

A lot of dissatisfied customers with that same model year. Good luck.

Change the fluid and throw in a bottle of Lucas Transmission Fix.

If that doesn’t make you happy, get a rebuilt installed.

Oh man, as the owner of a 2010 Ford Explorer, would you like to hear some stories about Ford transmissions?

Speed kills.

Play it safe...

Buy a Ford

Couldn’t help it - picked it up in the 60s when the muscle car competition was on between manufacturers....

Check the air filter, manifold absolute pressure sensor, and mass air flow sensor. Some models use intake air flow and pressure to determine shift points. Also, check that the transmission fluid levels are perfect after the transmission is warm.
