My TD SX crunches if I change too quickly into 3rd and sometimes 2nd gear when it's cold. I suspect dodgy syncromesh but it's only done a genuine 80,000 miles. Is that likely? Could it be linkage adjustment or is that wishful thinking?
As the gearbox is so hard to drain (have you tried to get a spanner in there to unscrew the plug?!) I think it's never been done. I've tried adding some Molyslip additive but it had no effect. My next plan is to make a plug spanner which will fit and change the oil. I thought about adding some slightly thinner oil to the mix in order to try to make it easier when cold. My thinking is that it does not crunch when warm as the oil has thinned due to being warmer. If I start with thinner oil it should be okay from cold perhaps? Bear in mind as well that a lot of cars just use normal engine oil for gearbox oil so I don't think it will do any harm. Any thoughts?
