Efficient mode transmission jerk (DCT)

Bigsean714 · 03-07-2019, 01:33 PM

Hello everyone, in 2nd gear in efficient mode when driving slow i barley tap the gas it'll sometimes jerk. I feel like the transmission doesn't know if It stay in 2nd or shift into 3rd. Is this normal? Also is there a way to reset the transmission?

Yes, it's normal with the DCT, the solution is never drive slow

It's a characteristic of a DCT. Can't baby the throttle.

Yes characteristic of a DCT. No matter if stock or GTS Flash.

We only see this in transmission auto level 1, doesn't happen in level 2 or 3.

And it definitely goes away as driving adaptation learns when we flash GTS DCT (we've tested this on and off).
