    Default 307 AM6 sliping and banging into gear

    Hi guys, first post here!

    I am having trouble with my new to me 07 307 136bhp AM6 110000km. I have changed the ATF oil with valvoline full synthetic max life just after buying the car, the old oil was wery Black!!

    Now the auto slips under load sometimes when changing down and bangs into gear, I am not sure if the new oil has made it do that or if it was already doing it beforehand?

    The maxlife oil I got is rated for JSW 3399. Does anyone know if I have used the incorrect oil?
    Or could it be another problem altogether?


    Thanks for reading.

    The AM6 box, the French designation for the Aisin Seiki AWTF-80 SC, uses a unique fluid. Because of this it is supplied by dealers. Fortunately for us, as Pug dealers want your eldest daughter, we can go to other makers who use the transmission to buy it, such as Toyota Type IV

    There are a few threads in AF about it.

    In some markets Aisin sell the fluid directly under their label. Not here.

    Welcome to Aussie Frogs! As seasink says, there are earlier threads discussing this very topic.

    Changing the fluid was on paper the right thing to do - it seems there is no such thing as "sealed for life" (or shouldn't be anyway). Here's hoping that using the wrong fluid hasn't caused permanent damage.

    Presumably you've only done one change? So a substantial amount amount of the original fluid would remain in the box (now diluted with incorrect fluid)? In any case, you will now need to drain all the fluid before refilling with correct fluid. Can't advise how - I'm no expert on autos .

    Cheers

    Hi thanks for the replys!

    I made two changes so there is about 7L of the new incorrect oil in the box. It actually runs fine until you load it hard or use the manual.

    Would doing 3 changes using Toyota Type IV oil be the best thing to do?

    I would get 3 x 4 Litre containers of Toyota Type IV oil and do the 3 changes, and see if it improves the gear changes.

    Hi guys

    In the weekend I replaced the ATF again but with Toyota type IV and all seams well! It is even using less diesel now.

    I was surprised how dirty the ATF was after a couple of weeks! on a positive note for putting the incorrect ATF in, now I have a super clean gearbox.

    Thanks for the posts pointing me in the right direction!

    Hopefully you haven't done any permanent damage having the wrong oil in the gearbox. I need to do both our 407's for peace of mind.

    I've used Penrite Fully Synth in my C5 X7 for a few changes over the years and it's doing fine. Clicked over 200k km today.
