DIY gearbox fluid filler. AND easy gearbox fluid change !

Disclaimer: The following is provided as a GUIDE ONLY, and neither myself nor Ozhonda take any responsibility for the outcomes of someone else doing the following. You follow these steps at your own risk!


Aim: To make a easy way to fill gearboxes...rather than use a sludge pump from the normal "fill" hole.

Required: scissors. about 1m of tubing ( any sealed type) with a maximum diameter of about 2.5cms. Cheap funnel with narrow nose.
Cost = about $5 all up.

Steps:

Grab funnel , and firmly push into one end of the tube.

Grab the other end , and cut a diagonal slit into it. This is to aid in directing the fluid into the gearbox ( not to mention guide the end into the VSS hole)

Thats it. DIY filler.

Now to use it....

Easy to drain fluid ~ jack up car , open lower drain bolt + catch all excess fluid. Place drain nut back in.
Now , open the 17mm fill hole ( located on side of diff housing)
Place a small container ( take away etc) under the open hole on hte ground below

Heres the easier part.

Lower car down to a "normal" ride height.
Make sure its supported by a BIG jack or on stands / bricks etc.

Take out the VSS ( located on the top of the diff housing) - simple CLIP it off. Then use a 10mm socket + extension to get down there and take out the 1 or 2 bolts , remove VSS.

Simply place the slit end into the hole carefully , hold up the piping and slowly pour the MTF ( or chosen fluid) into the funnel. It will slide down and slowly fill the gearbox.
Put 2 containers in , then slowly top up with 3rd container. Should take about 2.3-2.5 litres.
When its full , it will flow a small constant dribble out ( look !)

Once done , retighten 17mm fill bolt, place VSS back in ( be CAREFUL on the small 10mm bolts) and thats about it.

Easy !

Other comments

This Way is much easier , more accurate , quicker ( and less messy ) than using a sludge pump or similar. It pours the fluid thru the gearbox and then gives a very accurate indication of level.

Enjoy.

"normal" ride height, but the car still on the jack? Won't the front still be higher cause it has the jack on?

On the jack , it should be able to drop down to "normal" ride height.

You can do this with the wheel on or off - probably easiest to do the last filling step , with the wheels on and jack removed to give best level.

I assume the 2 bolts have been put back before filling it ya? Otherwise I'll have to jack the car up again to put the bolt.

As said ~ You re apply the drain bolt. Leave the FILL bolt off - this is to give you a gauge of how much fluid inside. When it leaks out slowly, thats it ! Put nut back on and finish up.

nice work, 1 rep point for you!

I assume this method applies to all Honda gearboxes?

Id say any FWD honda is pretty much the exact same principle.
Keep the "tube" alittle longer ( say 80cm) to reach larger engine bays etc.
Best thing about it , is that once you get the tip in firmly in the VSS hole, the fluid will 100% lead to the whole and properly fill :)

Beats holding a leaky pump under the wheel arch !

sure does! sort of on topic, anyone using the new Honda MTF fluid? Its in a white container with a white lid or something?
