    Thanks Ichiban.

    So I set about doing my 6 month oil change but also had a go at doing the gearbox oil. Milage is ~55,000 on an 09 plate.

    First of all I did the engine oil change, see the guide here:

    Guides - How to change the Engine oil on a i-DTEC engine • Honda Karma

    I use this:

    Eng oil.

    Next the Gearbox Oil change:

    The Car


    The tools:


    Man oil.

    Jack up the car, placing four axle stands in the appropriate place ensuring that the car is level. You will then need to remove the under engine cover using a 10mm socket (7 x 10mm bolts)


    The engine bay:

    Next you need to locate the Gearbox Drain bolt which is found between the Air Filter Housing and the Battery. I decided to remove the Air Filter sousing to improve access but I still needed the 400mm extension bar for a socket ratchet. I also bought a 3/8" square socket for a firm fit. This will do both the Fill bolt and the Drain bolt. Note, the Fill bolt does not respond to a magnet!


    Air Filter Housing:


    Gearbox Fill Bolt:

    The gearbox fill bolt is found between the Air Filter housing and Battery.

    fillbolt1b. fillbolt2. fillbolt3.

    The gearbox Fill bolt removed:


    Removing the Air Filter housing:

    The Air Filter housing can be removed by undoing two bolts and prising off the rubber grommet. Also removing the Air Hoses connecting to and from the housing. There is also a sensor cable plug that requires unclipping.

    filt in. filt out.



    The Gearbox Drain and Level Check Bolts:

    These are easily found. The views below are looking forward. The Level Check bolt requires a 10mm socket.

    gearbox1. Gearbox2.
    Undo the Drain bolt and drain the gearbox. Once drained remove the Level Check bolt and replace the Drain bolt using a new crush washer, these are the same as the Oil Sump Bolt crush washers.

    Using an appropriate funnel, fill the gearbox using the Honda MTF-3 Manual Transmission oil until oil can be seen coming out of the Level Check bolt hole. Replace the Level Check bolt and then replce the Fill bolt using as a new crush washer. I used about 2.2 to 2.3 Litres of oil.

    Replace the Air Filter Housing and the Under Engine Cover, take the car off the axle stands and job done!

    Not sure I would trust a minion on the paintwork though. :shock:
