    Default 4HP20 Oli Change

    I have just changed the oil for the 3rd time in 300,000km, on my 406 ST. It is now a challenge to see how long the transmission will last. So far its fine.
    However its not clear how to check the fluid level.
    Haynes says check with engine off, but I thought the convention was with the engine running.
    Any thoughts?

    If your 406 is indeed an ST, it has a 2 litre 4 cylinder motor. These had an AL4 gearbox, not the ZF 4HP20.

    The 406 with the 2.0 16V petrol engine (XU10J4R) was initially fitted with the 4HP20, but later switched to the AL4 in March 1998 (built date).

    The ZF 4HP20 can be identified by its two buttons next to the gear selector (sport and snow), whereas the AL4 had three buttons (sport, snow & 1).

    Well there you go, you learn something every day. A quick google shows that cars built before the 27th of March, 1998 used the 4HP20, and those afterwards the AL4.

    Certain mine is a ZF, luckily, and except for some strange Peugeot programming a far superior transmission.
    Question is, how long will it last?
    So far 300 000 km's.
    Interesting to note, each time I change the oil it is black, so something is wearing away.

    Or something is slipping and it's burning the oil? Is there debris in the oil?

    The early C5 V6 with the 4HP20 had a converter lockup point that was set too low and resulted in bad vibes going up hills at 60/70. Change it to the Peugeot software for the contemporary 407, which for some reason was set differently, and you had a different and much better car. Citroen never offered that software for reasons only known to them.
