My gear changes have gone notchy ... 2 to 3 in particular, just replaced my gear selector cable, £130 all in.
but still a little notchy, it feels notchy in neutral also ...
anyway, what gearbox oil should I buy ? Redline ? what type ?
Thanks All :worship:

I'm currently in the process of changing the gearbox oil in my 1.9 Multijet 16v, which I believe is a C530.6. The 120 is a C530.5 if I'm not mistaken.

It all depends on how much you want to spend tbh. I've just shelled out £53 (with a sneaky discount code) for 3 bottles of Redline MT85 from opie-oils

But you can also go for standard which is TUTELA 75w-85 from shop4parts

But any GL4 / GL4+ 75w-85 should be fine imo. If you've got any doubts, email opie-oils help desk at [email protected]. When I needed some advice, they were more than helpful.
