Gearbox Oil

Wheres the drain and refill plug on a 9A Gear box?

There are two 17mm Allen key sockets. The one nearest to the bulkhead and parallel(ish) to the floor is the drain.

The other is about half way up the ?diff? housing and is the refill/level. Make sure you can remove the refill one before you drain?…

Warm up the oil by going on a run 1st. If replacing all the oil you need 2litres. Some people use the speedo cable hole to refill but I?ve heard remours that the plastic cog can fall in the box. 75w90 multigrade GL5 is usually recommended I think.

Cheers
