I finally have the engine running pretty darn good on my 85 300 D. The car sat for a decade and I discovered that the radiator and coolant mixed. I replace the radiator and all of the hoses and cooling lines going to the radiator. I drained the old transmission fluid and replaced the transmission filter and transmission pan gasket.

The transmission fluid was a milky pink gooey mess.

Even after installing brand new transmission fluid it’s still very milky and thin and the transmission is definitely not liking it. I’m going to drain the brand new transmission fluid is there any other procedure that I need to follow?

I let the old transmission fluid drain out of the car for weeks before I put the new fluid in so I’m really surprised that there’s so much of the old fluid still in the system
