40mph, 1100rpm shudder/ buck

I am trying to get in this upcoming week, it went back to doing the same thing. Window of shutter is up to 1500 rpms. I get the feeling that they’re not going to do anything. Will see, will update with what happens.

 

Update, they are going to replace transmission and torque converter. 23163 miles on a 22 trains xp

 

Covered under warranty?

 

Yes sir! Was told that I was the second one that they have seen doing as well. Fingers crossed on the second one!

 

I have a 2023 OR bought new. At almost all speeds when in 6th gear it would shudder and feel like the transmission was slipping. It would especially do it in 6th gear at 52 mph, around 1200rpms. Took it back to the dealer multiple times for this issue. One of the times they discovered the transmission was half a quart low of fluid. They added fluid and said problem was corrected. It still did it, so I added a tube of Shudder Fix. Shudder Fix had no effect on the issue. I finally got the service adviser to ride with me to show them exactly what it was doing. They replaced the torque converter with 7000 miles on the truck. It drives much better now but not perfect. There is still a jerky feeling at lower speeds. I think there are so many of these 3rd gens with bad torque converters that people think it is normal. Even some dealers think it's normal because when they compare the customers truck with another one on their lot it would drive the same. That doesn't make it normal, it just means both trucks have bad torque converters.

 

I’m taking my 2023 in tomorrow to have the dealer check the transmission out. It is doing the exact thing the OP was dealing with. I have checked my fluid and it was fine. The transmission felt good when I did my test drive when I bought it. I love the truck, but it is hard getting past the transmission.

 

My issues only were present once the transmission got warm.

 

Make sure to drive it yourself and let the adviser ride with you or they will say, "could not duplicate the issue". I found a road that was flat and smooth near the dealership where I knew it would be obvious what the truck was doing. There was no way for them to deny the problem. Good luck.

 

Complete reman with torque converter. Took 10 days but it’s in there. We will see if it goes away?!
