Thought I would share this with you.

I made a transmission filler last night because when replacing the clutch in my gti I felt new gear oil was in order.

After refilling many 914 transmissions over the years I know what a pain it is.

Here is what I did

using one gallon plastic garden sprayer

I cut the nozzle a couple inches from the handle and attached about 6 inches of silicone hose with a small band clamp.

(got it off my old hand oil pump line.

then I put the gear oil in and pumped it up.

duct taped the trigger open and let it fill up..

worked great.

Brilliant -

Another solution, make the tunk plug removable

I just use one of these:

Now THAT is really good! And no wonder your tranny and axles are so clean too.

Is that an electronic speedo setup?

so the idea behind the one I made was, put 2.5 quarts of gear oil in the container, pump it up, lock the trigger and eat dinner, when dinner is done, the trans is full.

Yup

I do similar funnel idea, except with a slightly longer tube and run it out through the right rear wheel well just behind the tire.
