I have removed the battery and air intake assembly and got clear view of the top of the transmission. On the following pictures I have pointed out devices, purpose of which I don't exactly know.
This seems to be the cover of a device that is very similar to an oil-filter.
The black plastic cap removed, and the filter-like device.
There it is.
We have confirmed that that liquid is the transmission fluid, clean, honey colored oil, smells nothing like other fluids in the car, and obviously comes from the transmission itself.
We have removed that plastic cap with the yellow mark on it, and wondering if it is a possible fluid refill entry point.
The location of those two devices.
Since it was evident to us that the hole under the filter led to the transmission chamber, we gave it a try and started pouring in some fluid, and even though slowly, but it started going down. We did this to see how much would go down, and to test that our weld is leak-proof, assuming that the fluid reached the pan/bottom. We poured in 2 litres so far, until now there's none of it on the ground or around the weld.
So could any of you guys specify what exactly the function of those devices is? And also, does any of you have specifications how much fluid is required exactly? The one dealer I have called so far said it would be 7.2 litres for a completely empty transmission, but i will call a few more to get a confirmation on that.
Thank You for any comments, suggestions or opinions, I greatly appreciate it!
