transmission

We were towing a light fiberglass trailer (~6K lbs) in tow/haul mode on a very slightly rolling and winding two lane road (speed limit ~45 mph). Twice the truck seemed to get stuck in gear and wouldn't shift to a higher gear (in automatic mode). The RPM would hold at ~4K in 3rd gear. I tried...

Hello. I’ve been doing a ton of research (I am not good with vehicles or mechanical work) But I just recently purchased a 25 Lariat Powerboost with 3k miles on it. Thing is bad to the bone. But I’ve noticed that while im going from 3rd to around 2nd or below, I feel a small jolt. It’s...

Hey everyone, new 2025 F150 STX 5.0L v8 owner here! Loving the truck so far! This is my first pick up truck coming from a Honda Civic. Radically different machinery here. I’m so impressed.. I knew that these trucks can tow trailers but wasn’t aware of the tow mode until 400 miles into my trip...

Got an OTA update last week (don't know how to look at the version) and the trans has been way smoother since. Does Ford update the trans tunes via these over the air updates? It's usually a jerky mess like most 10Rs are but this week it has been smooth as butter. Trucks got 14k miles so it...

Just finished a 2,400-mile RV trip towing a travel trailer (3,000 lbs dry, likely 4,000+ loaded) with a truck bed full of camping gear and two fat-tire e-bikes on a rack above the bed. My wife and I were in the truck. The transmission was replaced at about 16,000 miles (the truck currently has...

First off this is my first post and first Ford truck ever… coming from a decade of running 3/4 ton rams and while I loved the deleted diesel it just wasn’t practical and started to have issues so I fell in love with the King Ranch I have had about a week or so now…so forgive my ignorance on some...

Hoping someone here may have experience with this issue as my dealership doesn't have a clue. Truck is a 23 Lariat 5.0 6.5 Bed 4x4 3.31 Issue started around 5000 km casually accelerating and I believe is shifted from 5-6. I thought I got rear ended that how badly the truck jolted when the...

Hi, I'm new to the group but somehow I think we have a connection through the other transmission complaints I have seen. I have a 2020 F-150 XLT, 3.5twin turbo 40k miles. Here is the list of issues so far. The engine falling flat between 3rd and 4th gear. Having a very spastic episodes if you...

Hi All, Purchased my dream truck back on Aug 2021, a F150 Roush from a dealer out in Orange County, California. Took it to my local dealer this Jan 2023, they charged me for diagnostics the first time around and said they couldn’t replicate the sound even though the sound was absolutely there...

2021 STX. 2.7L, 3.55 rear. Sometimes when my truck is cold and I leave my driveway it will shift to 3rd momentarily, then when I lightly decelerate it will slip like neutral then slam into 1st when coming to a complete stop. After about 200 meters of odd accelleration everything will seem...

Anyone else have their truck jump forward like you’ve been rear ended at stop lights? Started late June been to dealer 4 times with no resolution. It only does it in electric about 15 seconds after coming to a stop. Dealer ship figures trans aux cooling pump but I doubt that’s the issue...

I drove a 21 F150 King Ranch and I am on a trip out of state and I’ve started hearing a loud squeaking or whining noise coming from what sounds like the rear of my truck. It’s pretty Im loud I can hear it with all the windows up and it seems to be pretty much whenever I’m at low speeds applying...

2021 F-150 5.0 I was driving about 60 when I heard a loud bang, the truck stayed in drive, but acted as if it was in neutral. Got a service engine light on the dash. Pulled over, checked for leaks, found none. Turned off the truck and the problems all disappeared. Took it to the dealership...
