The short answer

The EAT8 is an eight-speed automatic with a torque converter that Peugeot developed together with Aisin and has used since late 2017. Complaints such as jerky gear changes, a hard clunk when selecting D or R, slipping or limp mode can be related to the fluid, the software or wear inside the gearbox. Not every odd feeling is a fault: in Eco mode the gearbox can freewheel between 25 and 130 km/h when you lift off the accelerator. According to TopGear, gearbox manufacturers such as Aisin advise replacing the fluid, even when the car maker describes the gearbox as filled for life.

What kind of automatic is the EAT8?

The EAT8 is a traditional automatic with eight gears and a torque converter. A torque converter is a fluid coupling between the engine and the gearbox. It gives smooth pulling away and smooth transitions between the gears. So the EAT8 is not a DSG with two clutches and not a CVT.

  • Manufacturer: according to Peugeot, developed in cooperation with the Japanese specialist Aisin. The Spanish trade magazine Motor16 and the French Actu Automobile name Aisin as the supplier of the gearbox.
  • Introduction: in October 2017, Peugeot announced the EAT8 for the 3008 and 5008 GT with the BlueHDi 180 diesel. In 2018 it also became available for the Peugeot 308 with engines including the BlueHDi 130 and the PureTech 130.
  • Successor to the EAT6: according to Actu Automobile, the EAT8 is about 2 kg lighter than its predecessor, the six-speed EAT6.
  • Freewheeling in Eco mode: according to Actu Automobile, in Eco mode the gearbox switches to freewheeling between 25 and 130 km/h when you are not accelerating and not braking. That way the gearbox reduces friction and fuel consumption.

Because the EAT8 uses fluid to transmit power and to operate the clutches inside the gearbox, the condition of the fluid is important. That applies to every automatic with a torque converter, including the ZF and Mercedes automatics we maintain.

Which models have an EAT8?

The EAT8 is fitted to models from Peugeot, Citroën, DS and Opel. Whether your car has an EAT8, an older EAT6 or another automatic depends on the engine and the year of manufacture. The table shows examples from the sources.

Which EAT8 behaviour is normal?

The main thing that is normal is freewheeling in Eco mode. It feels different from an older automatic, but it is not a fault. If you know what the gearbox does, you can better judge whether something is wrong.

  • Freewheeling in Eco mode: if you lift off the accelerator without braking, the revs can drop while the car keeps rolling. That is the freewheeling the gearbox uses between 25 and 130 km/h to save fuel.
  • Other driving modes: depending on the model, the gearbox has an Eco and a Sport mode next to the standard mode. The gearbox responds differently in each mode. That difference is a setting, not a fault.
  • Paddle shifters: Actu Automobile and Motor16 mention paddles on the steering wheel for the Peugeot 308 and the Citroën C4 SpaceTourer with EAT8. With these you choose a gear yourself.
  • When to have it checked: if the revs drop while you are accelerating, or a warning appears, it is no longer freewheeling.

Which EAT8 complaints need attention?

Complaints that need attention are jerking, slipping, a hard clunk when engaging a gear and a warning on the dashboard. These complaints are similar to those of other automatics with a torque converter. Use the RDW Kentekencheck, the online vehicle check of the RDW (the Dutch vehicle authority), to see whether there is a recall for your car. The table shows what the complaints can mean:

What you notice Possible cause What we do first
Jerks or knocks when changing up or down Ageing fluid, learned values or software, wear of the clutches inside the gearbox Test drive cold and warm, reading the fault memory, assessing the fluid
Hard clunk when selecting D or R Fluid level, fluid or control system Reading the fault memory and checking the fluid level at the specified temperature
Revs rise without the car accelerating with them A slipping clutch inside the gearbox or too little fluid Driving no further than necessary, reading the fault memory and checking the fluid level
Warning on the dashboard, gearbox stays in one gear Limp mode caused by a fault in the control system or a sensor Reading the fault memory before any parts are replaced
Fluid stain under the car near the gearbox A leak at a seal, line or cooler Tracing the leak, checking the fluid level

General explanation for automatics with a torque converter. Which cause applies to your car only becomes clear after investigation.

You can read more about jerking and its causes in our article on an automatic gearbox that jerks when shifting.

Is the gearbox in limp mode, is it clearly slipping or is it losing fluid? Then drive no further than necessary. Driving on can make the damage worse. Read what you can do now in our article on an automatic gearbox in limp mode.

What maintenance does the EAT8 need?

Check the service schedule for your model first. If it includes a change of the automatic gearbox fluid, that is the requirement. If it says nothing, the manufacturer treats the fluid as lifetime fluid. The Dutch edition of TopGear wrote in September 2026 that gearbox manufacturers such as ZF and Aisin still advise replacing the fluid, even when the car maker says it is not necessary. What filled for life means is explained in our article on sealed for life gearbox oil.

Our own cautious advice is to have an automatic with a torque converter, such as the EAT8, flushed or its fluid changed every 60,000 to 80,000 km. That is not a factory requirement. If you often tow a caravan or trailer, drive a lot in the city or do not know the service history, use the lower end of that interval.

  • The right fluid: we use fluid with the specification set for your gearbox.
  • Filter: if the gearbox has a replaceable filter and this is part of the agreed job, we replace the filter and the seal.
  • Fluid level: we check the fluid level with the car level and at the specified temperature, following the gearbox manufacturer’s procedure. Too much or too little fluid can cause shifting complaints.
  • Learned values: on some gearboxes these can be reset after the maintenance. You will hear in advance whether that is needed for your car.
  • Test drive: a final test drive follows the work.

According to TopGear (September 2026), changing automatic gearbox fluid, with the filter if needed, costs € 350 to € 600 on average. With us, you receive a quote in advance based on your registration number. How we treat the automatics of these makes is explained on our page about automatic gearbox flushing for Opel, Peugeot and Citroën.

How does the mechanic find out what is wrong with the EAT8?

The mechanic starts with a conversation, a test drive and reading the fault memory. Only then do you hear whether a flush makes sense or whether something else is going on. This is how it works in our workshop:

  1. Intake: you tell us when the complaint occurs: cold or warm, when pulling away, at a certain speed or when changing down.
  2. Test drive: the mechanic reproduces the complaint and pays attention to the moments of each gear change, jerks and slipping.
  3. Reading the fault memory: where possible, we read the transmission control unit for stored faults.
  4. Fluid and leaks: we look at the condition of the fluid and check for leaks at the gearbox.
  5. Advice and price: you hear what we see and what it costs. We only flush the gearbox if it makes sense and only carry out extra work once you have agreed.

A flush is maintenance, not a repair. It does not fix internal wear, leaks or electronic faults. The treatment itself usually takes two to three hours, and the car is often ready the same day. Read more on our page about automatic gearbox flushing in Rotterdam.

How do you check whether there is a recall for your car?

You can see whether there is a recall for your car for each registration number in the RDW Kentekencheck. According to the RDW, the manufacturer informs the owner, usually through the Dutch importer. The RDW passes on the owner’s address for this. Once the manufacturer has reported the repair as done, the recall no longer appears in the check.

Have you received a letter about a recall? Then act on it. According to the RDW, the repair is carried out by a garage appointed by the manufacturer, often a main dealer, and is free of charge. For maintenance and complaints that are not covered by a recall, you can also go to an independent garage.

Frequently asked questions

How reliable is the EAT8?

That depends mainly on fluid maintenance and use. The EAT8 is a traditional automatic with a torque converter, a design that has been in use for a long time. If your gearbox has complaints, have the fault memory read first before any parts are replaced.

Is the EAT8 a DSG?

No. The EAT8 is an automatic with a torque converter and not a gearbox with two clutches. That is why it behaves differently from a DSG and needs different maintenance.

Why do the revs drop while I keep driving?

In Eco mode this is often the freewheeling function. The gearbox then disengages between 25 and 130 km/h when you lift off the accelerator and do not brake, to save fuel. If the revs drop while you are accelerating, something else is going on and having the fault memory read is wise.

How is the fluid level of the EAT8 checked?

In the workshop, with the car level and at the specified fluid temperature. Many modern automatics have no dipstick, so you cannot check it yourself. If you see a fluid stain under the gearbox, have it checked.

Does a flush help with a jerking EAT8?

Yes, if the jerk is caused by ageing or contaminated fluid. A flush can then reduce the complaints. It does not help with wear inside the gearbox, leaks or an electronic fault. That is why we read the gearbox first and take the car for a test drive.

Can I tow a caravan with an EAT8?

Yes, within the permitted towing weight of your car. Towing puts extra strain on the gearbox, because the fluid gets hotter. In that case, use the lower end of the maintenance interval.
