Hello, I have a 1999 Jeep Wrangler with a Manual Transmission. I need to know the procedure for changing the fluid. How much does it hold and what type of fluid should I use. Should I use ATF or 90 Weight?

Thanks.  

You can either use some rags to make a dam and drain the fluid right on to the skid or you can remove the skid.

Take out the fill plug first, then remove the drain plug. AX15 transmissions use 3.3 qts of 75w-90 GL-3.
