Hi Chaps, i have noticed the gearbox seems a 'bit' more notchy than usual

TBH i cant 100% remember when i last changed it but it must of been around 20k miles ago, do you think i should change it or will it make F.A difference??? I'm off work tommorow so i could do it - I thought the schedule was quite a bit more than 20k!!??

Gearbox was replaced by previous owner @Honda though this was over 4 years ago

First thing just to check I'm correct when replacing gearbox oil its 75W90 and requires 1.5 litres?

Last time i used Motul stuff.

Thanks in advance

P.S

I used Motul last time, but is there any other brand(s) people recommend if i do change it I'll have to get some from a shop NOT honda (bit far away even though there stuff is generally good).

My 5th gear used to crunch when doing full boar 4th to 5th changes.

Since changing to Castrol SMX-S, it hasn't any more

Really nice smell to that SMX-S too

Might give this a shot then? you reckon its worth it and will help notchiness Ron?

When are you supposed to change the gbox oil at what mileage? according to the FAQ service sheet its 72k miles?

Whats rating of the castrol smx? 75w/90?

Ultra_Nexus

75-85w, but you can get 75-90 IIRC.

Since changing to it I have really noticed an improvement!

Personally, I change my gearbox/diff oil every 2nd engine oil/filter change which works out every 8-9k miles

I do excactly the same Do not leave your gearbox oil for so many miles.

If you use Amsoil 5W-30 you will never go back to any other tanmission oil

I was actually going to try Amsoil but i bought some Castrol edge in bulk and it seems to be good so far.

I have redline in my diff

Redline MTL chap

Redline is a very good choice too for diff oil . I use LE for my diff. It supposed to be one of the best but a bit expensive though

Do not know about Castrol in transmission so i cannot comment
