what tools to change gearbox oil ?

[dridgy]

Hi guys,
I want to change the gearbox oil on me van, it looks like the plugs are these big allen key jobbies.
what size are these plugs and where do i get the tools from to undo these plugs?
any help appreciated.

thanks

If its the same as mine you need a 17mm drain plug bit, you can get them from Halfords or most car places, access can be a bit tight depends on your system, i managed the filler one without dropping the gear links but the drain plug was a beggar to undo as it was so close to one of the exhaust pipes, use lots of plusgas and a long breaker bar.

Take the filler off first coz if it won't budge after you've let all the oil out you'll have fun getting the new stuff back in through the drain.
