Hi All,
I've got a 2004 6 speed and think a gearbox oil change is long overdue (not had one for at least 12 years, possibly never? But car has only done 36k miles)
I've taken the speedo cover off to have a look at the oil and found the oil was only about 2cm below the cover. From what I've read it shouldn't be this full. I was planning to drain via the 24mm plug and then refill via the speedo cover (not got ramps so access underneath is difficult), and use the hex filler hole to set the correct level. I'd expect to put in about 1.8l but I'm nervous about putting back less oil than it has now...and has been running happily for more than a decade.
Thanks for any advice. ;D
You can do it without ramps without any bother although it's easier if you jack it up from the nearside to make it easier for reaching in at the drain and fill holes. Just sit it back down to fill it up.
Helps to take the airbox out to see where you're feeding the hose down for filling but there's a very good "how to" in the academy section here.
1.8l is the recommended fill which SHOULD just start coming out of the fill port, regardless of whether you use that or the top one.
Just make sure you can get some fresh in before you drain the existing stuff (I know you've already had the top plug out)
Thanks for the tips ;D
Can you confirm how much oil I will need? I see some posts on here (including shnazzle's excellent how to's) say 2.1l/3 bottles whilst others say 1.8l and 2 bottles is enough?
The six speed box takes the larger amount of oil. The unused speedo hole will be very close to the top with the correct amount of oil. I do know the five speed box will overflow if you fill that way. I did it once, but jacked the rear of the car up to prevent the overflowing.
It's best to use the filler plug as your fill point because it will set the level properly. Remember, when you drain the box, not all of the oil comes out, so the required amount to refill is a slightly variable quantity.

When I did mine (not ramps) I tried to fill by using a funnel and long piece of tube down into the filler hole. Nightmare.
Gave up and bought a 500ml syringe and it was a doddle.
That's great - thanks all for your help 8)

Yes, I did consider Red Line as it is well regarded by members. In the end, as I don't have any issues currently and I'm pretty sure it isn't Red Line in there at the moment, I went for fully synthetic GL-4 from Comma that's on offer in Halfords at the moment :)
I've not changed the oil yet...job for a wet Saturday :))

Halfords also had Comma brake fluid at a good price earlier in the year, maybe still do.
