hopefully.
what do you mean by 'catch' going from gear to gear ?
crunch ?
or sort of hang up ?
If the clutch disengages cleanly, like van does not start to move in gear
until clutch pedal is say, 2 1/2 inches off the floor ...
that tends to indicated complete and full clutch disengagement ..
and if that's the case , then any crunching would be more like a worn syncro
issue.
I also find draggy/dry/worn shift linkage on vanagons a lot. Like people
are driving them that way, and since they don't drive other vanagons with
smooth well lubed and adjusted linkage , they don't even realize how
draggy/dry their linkage is.....
not that that applies to anyone on this list of course !
For minor gear shift crunching ....I have improved or reduced that with
Prolong Transmission Oil Additive. I like that stuff added to Redline
MT-90.
I'm amazed at how well grease seems to stick on surfaces and lube them for a
long time.
I use a really good synthetic grease in the pilot bearing ..
like I have some Redline red grease - I use that on the pilot brg.
but for sliding surfaces in the clutch mechanism I use 'black slimey'
molygraph grease.
for the cross shaft bushings...a really good synthetic penetrating spray
grease. Until the shaft just flops around practically ...it's so well
lubed.
same for the clutch pedal pivot and clevis ..spray up in there.
it's bare metal to metal on the clevis pin in the clutch pedal - very cheap
construction for sure, especially since you can barely get to it to lube it
, and they do wear out there - mostly on syncro vanagons though.
