Jerky shifts into third and fifth gear

[jacobsho]

In my 2018 SHO, I’ve seen that my shifts from second to third and fourth to fifth have some issues. For going into third gear, sometimes the transmission hesitates and jumps up a little bit for no reason, like going from 2700 -> 3000 rpms. I also launched my car in late March and the car went into (what I hear is called) limp mode, where I couldn’t reach 60 because it wouldn’t grab the third gear and practically went into neutral. For going into fifth gear, the car will approach 40 mph, but then it will jolt the car into fifth gear. I bought the car with 70k miles and got the OEM transmission fluid drain and filled around 77k miles after some issues, which helped a decent bit, but it’s still happening.

If you only did a drain and fill it may not hurt to do it again or have a shop do a full flush. Are you getting any DTCs and does it only lose gear when you have foot to floor or does it do it under normal driving?

Do you have any issues with reverse?

Having a similar issue. I'm going to drain/fill the transmission and add some shudder fix to see if that fixes it.
