EAT8 problem during low speed

General Discussion Technical Documentation

Hi everyone,

I’m driving a 2019 DS7 Crossback 2.0 HDi with the EAT8 automatic gearbox, and I’m experiencing some issues that I’d like to check if anyone else has had.

The gearbox is not working perfectly under acceleration. At low RPM and light throttle, especially during upshifts (e.g. 2→3, 3→4, 5→6, 6→7), I feel a slight shudder/vibration through the car.
It also sometimes happens during downshifts (e.g. 6→5 or 5→4) at low speed.
At very low speeds and low RPM, there is a kind of rattling sound, almost like a metal vibration.
When I press the accelerator more (higher load), everything becomes perfectly smooth.
There are no vibrations at idle.

Also, when I use Tiptronic to manually change gears and the RPM is over 2000, there is no problem.

Has anyone had a similar problem, and what could be the possible solution?

Thanks in advance!

What’s the car’s mileage?
The EAT8 sometimes has leaks in the hydraulic oil cooler. It might be worth checking.

Engine mounts, gearbox mounts. Higher rpms less vibrations, so might be worth checking those.

Also, i presume gearbox oil has never been changed so that should be done anyhow. While doing it you will see verify how much oil was there actually, and are there any leaks, etc…
