We are an independent service specialized in oil and filter renewal, adaptation reset, and software updates for PSA EAT6 and EAT8 (Aisin-built) automatic transmissions in Peugeot, Citroen, Opel, and DS vehicles. At our workshop in Kadosan, Ümraniye, we restore your vehicle's shifts to that factory feel through computer-based fault diagnosis, guaranteed workmanship, and a transparent process. We never push unnecessary parts replacement; we make the correct diagnosis first.
PSA EAT6 and EAT8 transmissions are torque-converter automatic systems built by Aisin, with 6 and 8 forward gears respectively. These transmissions are widely used in the Peugeot 3008, 5008, 308, Citroen C4, C5 Aircross, Opel Grandland, Astra, and DS models. As part of our service, we first connect the transmission to the diagnostic computer and read the stored fault codes and adaptation values. We properly drain the old ATF oil and filter (cartridge filter or internal strainer, where applicable) and refill with the correct amount of the manufacturer-specified oil type at the correct temperature. After the procedure, we reset the shift adaptation values, load the latest control unit software when needed, and verify shift quality with a road test. The entire process is documented.
If you notice any of the symptoms below, a prompt expert inspection is important.
Shock, hesitation, or delay felt especially in the 2-3 and 3-4 shifts is often a sign of degraded ATF oil and drifted adaptation values. We pinpoint the real cause with a computer-based inspection.
Revs climbing while the vehicle lags when pulling away from a stop can indicate low pressure in the clutch packs or torque converter. We measure pressure and solenoid values via live data.
Delay or free play felt when changing position with the shifter points to adaptation drift or a hydraulic pressure issue. We diagnose first, then intervene.
When the fault lamp or a transmission fault message lights up, do not push the vehicle. We read the stored codes and distinguish whether it is an urgent mechanical fault or a software/adaptation-related issue.
The vehicle hanging at the revs without upshifting, or dropping into limp mode, can stem from a sensor, solenoid, or oil quality. We perform a systematic inspection.
City stop-and-go traffic, trailer towing, and long climbs wear out the ATF oil quickly. Even without an obvious fault, periodic oil and filter service extends transmission life.

“Jolting had started during shifts in city traffic. They connected the car to the computer first and explained what was going on point by point. After the oil and adaptation, the car felt practically brand new. They didn't replace anything unnecessary; they did it the right way.”
“I had vibration when setting off and the revs hanging. Somewhere else told me the whole transmission was gone, but when I came here they took measurements first and said the problem was the oil and adaptation. They offered a much more sensible solution, and the car is doing great now.”
“I panicked when the transmission warning lit up on the instrument cluster. They read the codes and clearly showed it was software and oil related. They explained every step, and I was completely at ease because I knew what they were doing. They handed it back after a road test.”
