Now this is directed to the average everyday daily or street driven vw's. I have had a problem with my trans grinding into 2nd and 3rd if I don't pause before each shift and when I down shift into 2nd. I have already replaced the shift bushing and the trans mounts so those possibilities are out. I know the possibility of the syncro being shot could be the case too but I want to check every avenue before I replace the trans. I recently discovered that a specific gear oil, GL-4 should be used in our vw transmissions and using anything else can cause what I am experiencing. The weight of the gear oil isn't the issue, it is the type of gear oil that is the main concern of this thread. I haven't confirmed MY issue yet but I have heard that the use of anything but GL-4 type gear oil doesn't coincide with the material that is used to make the syncro's. I will keep everyone updated and if someone is already aware of this issue please ad to this thread to help us all out!

Redline MTL. I have this in all my VW gear boxes as well as the diff and transfer case of my work truck (2500 dodge 4x4). I was first introduced to this product in 1986 when my then employeer was racing GT 5 in SCCA. he had lost a drainplug in the gear box (unbeknown to us at the time) during a race at Atlanta Motor Speedway. Not only did he finish the race but won. When we went to service the car before the next session we found the missing drain plug. I have used it ever since
