Shuttering / vibration

[coyote5.0man]

Is anyone else experience shuttering or vibration when the truck is shifting from 1st to 3rd gear? I noticed the transmission skips second gear altogether if you are driving normally. "my truck may have used second gear twice since I've owned it" Each time you take off you feel like a shutter or vibration, it pauses while the transmission is shifting from 1st to 3rd gear. Thank you

Ok obvious questions, what year and how many miles?

Sorry good point. 2022 FX4 lariat and I'm currently at 2,170 miles

Have you tried using S mode? If not try it and see if you're still getting the shuttering.

That is a very good idea. I will try that. Thank you

Since I tuned mine I don't notice the shuttering at all. But before that I would notice it slightly and dropping it into S mode took care of it. Just remember that if you hit the +/- button on the side while in S mode you'll now have to manually shift.

I guessing what you're feeling is the engine lugging a bit. What RPM is it dropping to when it first hits 3rd?

It sounds like feathering the throttle during break-in period or trying to save gas. It try’s to learn your driving habits.. maybe a little more throttle on take off..??

It's still in adaptive period. Mine was fine until around 10k miles. Then I got the skip second shudder. There's a TSB on it. They reset whatever controls the shift points. Now I drive less Granny-like and I'm at 17,000 without a repeat of the issue..

Can you please list the TSB number for the 2022 year? I would love to have that TSB done. So are you saying it should not skip second gear? I have never see a transmission do that before so if there is a fix that will correct that I want to have it done ASAP. That can't be good for the trans or the engine.

TSB 22-2139

Mine only did it when cold. Once warmed up, the issue went away. I assumed it was trans fluid level but they checked it and it was ok. Since the TSB everything has been great but I didn't start experiencing it until 10k miles and I haven't reached another 10k since. The real tell will be whether or not it returns before I reach the second 10k.

It's is normal for automatic transmissions to skip second gear (or any gear) under the right conditions but not every time. Mine was jumping 2nd when it shouldn't have and was causing what you described.

You can also try tow mode. It's a good compromise between normal and sport

looking over this TSB, it looks very invasive. Did they have to take the trans out of the truck?
