I was also told to add something called "Lucas tranny additive" How much of the 75W90 do I put in and how much Lucas do I put in?
Yup I put it in the last time I serviced the 5 speed. Altogether you use half of the bottle of lucas about 350ml and the rest gear oil. You know when to stop filling when you have the gear oil spilling out of the bottom of the filler hole/check plug and just screw it back. Btw I used an 80-90 oil.
