Ive done some reading on here and so far know that I'll need 3.5 ltrs of 75w 90 for a 5 speed box. Ive checked the dip stick next to the gearbox mount and its dry!! so My question is - how do I drain what might be in there, and how do I re-fill with lovely new oil!?

Please help me fella's as I dont want my box giving up on me!

 

thought it was 4.5 litres something to do with covering third gear,drain plug at bottom of gearbox under car,fill with funnel carefully hope this helps

 

oh...I read 3.5 litres on here!? Will maybe have to dig a bit deeper to find out for sure. So fill carefully through the dip stick??

 

4.5 ltrs is for the 6-speed. An extra half ltr in the 5-spd box is ok
The drain plug is at the bottom of the front diff. Fill through the dipstick hole. Ideally, you'll need a tube to allow you to reach the hole from the 1 ltr bottles. Stand the bottles in a saucepan of hot water for a while to warm the oil for better flow, when filling.
