Hey everyone, I have some questions for people who prays with flluids- I dont have money for rebuilding trans.
Until my tranny gets super hot ( which is almost 1hr of fun driving) my gear change 1-2 is very crunchy/notchy, etc when it is cold.
After 1hour of 3-4K rpm driving, my 1-2 gears are smooth as new.
I am currently running Pennzoil Synchromesh fluid in my O2M VW/Audi 6spd Manual. 75W GL-4 is factory fluid. 73K mile.
I did money shifted once. Mistakely pushed my gear knob in 1st gear until it made grinding sound with clutch pushed in, at 55MPH! Didn't went thru, it was going in and grinding and I pushed knob back asap. All clutch in so no engine damage.
After changing to Pennzoil Synchromesh fluid it doesn't grind at all but just notchy and lil crunchy. 1-2 gear goes in with vibrating feedback from knob when it is cold.
The fluid I had 1-2 gear change high rpm grinding was Febi 21819 GL-4, for VW manual trans. 40.8 cSt at 40c (104F) and 6.7 cSt at 100c (212F).
Btw,
I found this:
BG Synchroshift II 37.85cSt at 40c(104F) and 7.11 cSt at 100c(212F) and GL-4 applicable [not sure it is full syn, but they have Mercedes approval (Mercedes Benz PN 900260315)]
Pennzoil Synchromesh 41.6 cSt at 40c (104F) and 9.08 cSt at 100c(212F) GL-4? (heard it is dino oil)
I heard MTL MT-80 is thickest among this , 50.8 cSt at 40c (104F) and 10.4 cSt at 100c (212F) and these are full syn.
Does viscosity matters a lot for smooth gear? or the friction materials matter?
My Febi fluid was 40.8/6.7, which is thinner than synchromesh fluid but synchro feels better with synchromesh.
Should I try MTL MT-80 or BG Synchroshift II?
Clutch is already bleeded and my car uses hyduralic clutch system if that matters, but I am sure my clutch life is almost done because most of Audi TT 8N owners replace their clutch around 72~78k mi.
+ VW official fluid for my car is

+ VW official fluid for my car is
VW G052527A2- which is 75W80 or
VW G070726A2
I think.
