Thanks for all the responses. I was going to draw the fluid out with a large syringe and tubing since it's a small amount. Also, since its important to get the level correct I figured this would a good menthod to add fluid.
Have a 86 E32 with a 24 hp diesel and a Hurth transmission. I'm having trouble obtaining the Type A fluid required. I have found only one reference on the internet suggesting a replacement of Dextron II/Merc. Can anyone suggest where to obtain Type A or if a reliable subst is being used.
