small grind while upshifting from 1st to 2nd and 3rd to 4th

All,

I'm new to my 2004 jetta tdi with 67k miles.

I've noticed that it likes to grind from 1st to 2nd and 3rd to 4th if I shift too quickly. Of course I can drive it like and 18 wheeler, but that's not really what I'm going for.

I've read about the different fluids. Does anyone have experiences with both the synthetic and mineral trans oil? The synthetic is pretty expensive, but would be worth it if I could shift fast.

Thanks

Chris

Well I wouldn't have thought that it would grind once you are moving because the syncros match the shaft speeds. I suppose it depends on how quick you are quick shifting?

You don't need synthetic fluid for a clutch Chris there is no heat involved a good old DOT 4 will do. Plus you can't mix/change fluid on a system that isn't designed for synthetic. ;)

Yes. It's surprising to me as well. Having driven old BMW's for years, I'm used to downshift (3rd to 2nd) grind. I wasn't talking about clutch hydraulic fluid, but I do wonder if a maybe there is some delay in the actuation. Does a stainless braided clutch line help this?

I was wondering about synthetic vs mineral fluid in the transmission. I think the current recommended mineral based oil is G060 726 A2 (g052 726 a2). The current synthetic is g052 171 a2.

I like to shift quickly, but am not ridiculous...

I would go with G70, get if from your local dealer or boraparts.com I would go with synthetic for sure.
