I've got a 93 W250 with the A518 auto trans. I started out to just service the tranny, fluid, filter and gasket. The truck doesn't get driven much and the tranny seems to be working fine, truck has 114K miles on it. Now I'm wondering if I should try to make some adjustments since the pan is off. They would include the front kick down band adjustment, rear band adjustment, line pressure and shift points. I've never tried anything like this and am wondering, should I mess with it, or leave it alone. What advice can you guys give me.
