    Default ZF 4HP14 Automatic Transmission

    I enquired at my local Automatic Transmission Specialist (the sign says they specialise in European Transmissions) about the cost of a service. I have a 1995 Citroen Xantia, but the box is also found in BX's and Peugeots (405 & 406). The cost was about $170.

    I enquired as to what this entailed. Basically, they just drained the oil and filled it up. They mentioned the sump was just to keep the oil in, it didn't hide any thing to be serviced and wasn't removed. The filters required a complete overhaul of the transmission to replace them, so this wasn't part of the service.

    The only reason I asked was that one of the two drains plugs felt like the Allen key was about too burr the recessed hole when I last tried to remove it. I have been looking for a spare one before trying again, just in case I stuffed the drain plug.

    In the past with both BXs I have owned and this Xantia, I have always dropped the transmission oil at the same time as dropping the engine oil (each 10,000kms). I check the amount drained to confirm I am not losing any and refill with 2.4 litres of Castrol Transmax M, a Dexron 2 oil (don't use Dexron 3 or later). Buying my own oil, I am saving about $140 doing it myself.

    John the 205 Si auto also uses the ZF 4HP14 Automatic box.
    There is a service kit readily available, Daewoo used the same box.
    Kit contains a gasket and a filter.
    As you say very important to use Dex 2.
    My silver Si was sold to me with a known problem with the auto.
    Ran ok for a while then was reluctant to shift into top. Rapidly deteriorated to stage where only operable gear was reverse.
    Oil that came out of it was black and thin, Dex 3 I guess. Filter was clogged with bits of gasket/friction material?
    Replaced gearbox with one from a tailended 205. It was full of lovely fresh looking red oil. Hasn't missed a beat so far.

    How many other ZFs out there are being fed the wrong diet?
    Lots of mechanics I have spoken with are unaware of the need for Dex 2
    Even a well respected Australian Oil Company lists Dex 3 for the ZF 4HP14.

    Another problem that has been reported overseas concerns the "donut" heat exchanger that bolts to the top of the gearbox.
    Some of these have broken/corroded allowing water to enter the gearbox.

    The filter is concealed inside the valve body; does not look hard at all to access. Also there is at least one band adjustment possible from outside the casing.

    I'm sure if you posted up the dimensions of the drain plug it would match something else.

    I use dexIII in my 4hp14. Shifts perfect. I found a 205L of dexVI at work, that will be going in next change. I got my filter kit from bursons, was under $20. And yes 1 band adjustment from outside.

    I am glad that I didn't take it to the "professionals". They stated that they didn't remove the sump and only changed the filter on a complete rebuild of the transmission.

    The car has done 150,000kms on the speedo, but I think 170,000kms is closer to the truth as there was speedo cable problems with the owner before last. As that owner was a businessman and I have the complete maintenance history, I was able to ascertain the 20,000km discrepency by analysing the service intervals and the tyre changes (fortunately done at the same place). The owner before me had the speedo cable replaced as soon as he acquired the car and realised it had a problem. Either way, I expect the transmission to last between 200,000km to 300,000km going on my BXs. At 10,000kms per year, I won't worry about replacing the filter.
