RE: Changing Transmission Fluid in ML 320
I want to change the fluid because one of the trans cooler lines was leaking in 3 different spots where the rubber metal, and one at the transmission. The car has about 80k miles on her. I suspect the fluid has been leaking for some time and it's low. I think the car hums a little bit louder than it should. The ML has no dipstick. It has a cap with a locking tab that says "MB Tech Only" over the sealed fillter tube. I already purchased the dipstick from the internet. Somehow I got lucky and escaped for $31. People out there are trying to sell that thing for upwards of $80. I also scooped up a mitchell cd which has an a/t trans service procedure but it makes no mention of the differentials.
