I also have a full synchro in my bug and I just recently switched to Valvoline Syn Power full synthetic 75/90wt. It has made a world of difference on shifting! Cold shifting is now very easy.

For my 1955 tranny,
Would this oil be fine to put in?.. not sure about the comment of "rear axles not requiring hypoid oils" - just don't get that.
Dang cracked axle boot..
Thank you

OK... pricey.... but I have to admit, my transaxle is worth it.
Of course I read the 70+ page on GL4, vs GL5, as well as another thread, and for me.. want to go with GL4...which I think the redline is... have to double check.
Thanks all.

Scott who owns MCM rebuilds racing transmissions for VW cars. He swears by Redline. He turned me onto Redline and I have not gone back!

Another confirmation, thanks!
Soon I will be changing out my 77 bus tranny fluid... if anyone continues to read this, do I used the same oil?
I can ask this in the bus forums otherwise....

VWs don't have hypoid ring gears so it should be fine, however, the consensus is that the Redline oil is the best.

The dedicated gear oil topic is now 70 pages long. There is no consensus on what oil to use.
Since Matt is asking about his 77 Bus, it does have a hypoid R&P, so it needs to use GL-5 gear oil.
Now, for all the nancys out there that fear GL-5, there do exist gear oils that are GL-4 and GL-5 rated.
I strongly recommend synthetic 75W-90. Then when the gear oil is cold, it shifts just like when the gearbox is warmed up in the summer.

It was just pointed out to me, that early transaxles use different bearings and "might" need a different gear lube than newer transaxles, so I unlocked it.
Please, if you have questions on other transaxles use other existing topics.

My point to Glenn was, that the early non synchro roller bearing transmissions are much more primitive than the later transmissions. What they were originally intended to run, and what works best in them now, and why is not really the same discussion as the dedicated oil thread..
I've got a few things to add, when I'm back on my laptop

I don't know the problem, but simply use the oil VW recommended to use and used itself. Is it really that hard?
Transmission: mineral oil SAE90 GL4 after MIL-L-2105. I drive every day since 20 years beetle only, summer and winter. You can also use 80W90 if you want. |

That was a lot of years ago and things change... usually for the better. Oil today is better formulated than it was in the 50's.
When light bulbs need to be replaced, in your house, do you insist on finding incandescent bulbs or do you use LEDs?
