The is AC/Delco Synchromesh and then there is AC/Delco Synchromesh FM (Friction Modified).


The latter is what I use and it's a great trans oil for the A4 5 - speed.

Commenting on an old thread but I used this GM fluid:
ACDelco-10-4006-Synchromesh from Amazon and it made a newly immediate difference in shift quality and cure my third gear clash I was experiencing.
I changed the factory fill at 120,000 miles and ran G072 (I think) until about 160,000. I had problems with third gear for the past year until I used the GM Syncromesh.
ok. old thread eh? i found one yesterday that hadn't seen use sense 99 and i thought about reviving it just to ask my question but the thread answered it for me so i didnt... kinda wanted to any way tho.
