I've got some shift problems with my VW 411. Just to try a quick and simple solution I changed the transaxle oil. In my (original) instruction book I found that there is 2,5 liter in the gearbox, You've got to let it out, and then fill it with (only) 2 liter.
So, I did. Problems wheren't solved, unfortunatily.
But now my question is: I've let out 2,5 liter and filled only 2 liter. Isn't that 0,5 liter to less? And will that cause problems?
For info:
I measured the quantity of the old oil > and it was 2,5 liter
I've filled 2 liter new oil > till it fluid over, just like the instruction book says
After the change I drove 100 km home, without problems (yet).....
