Gearbox oil to help syncro crunch
Hi guys I have a crunch when im changing upto 4th (not back down) Im pressuming the syncro. I have read on a lot of sites about the GM Syncromesh and its magical powers that has stopped the crunching !!!!
I cannot seem to find it available anywhere allthough im a bit skeptical.
Is there such an oil that can help with this or have I got to just face up to the fact the box is going to have to come out and cost me a fortune....
What about the castrol syntrax ? I heard this is good but not suitable in a sti type r ?
The car is a my99 type r by the way as I think it makes a difference that it has the dccd.
Any info would be appreciated .
thanks in advance
