I'm new to this forum as I only recently bought an E320 4matic wagon, 1999. It has 105,000 miles and I have a stack of service records 2 inches thick. Literally everything the dealer tech recommended was done.....Or at least it was listed on the R.O. One thing notable is the lack of a transmission service.
Yesterday I changed the trans oil and filter and drained the torque converter. I've changed a lot of auto trans fluid in my 40+ years working on cars. This was as dirty as I've ever seen. There was gray matter in the goo on the bottom of the pan. Looked like lead I used to find in engine oil pans from the days of leaded gas.
Anyhow I balked at paying $25/qt at the dealer for oil. So, I researched the specs and found that on 722.6 transmissions, Valvoline Max Life claims to meet the spec. A bottle I have from summer 2010 lists the 3403 spec that has been discussed on this and other forums. The Max Life Fluid I just bought lists the NAG-1 spec.
I changed the fluid and filter and after 50 miles it shifts just fine. If the trans craters anytime soon I will let you all know.
All this said, I was unable to measure the fluid level in the pan by any method: bicycle cable without housing, clear plastic tube or anything else I could stick into the filler tube. They all stop at the same place. So, I assume there is a screen at the bottom of the tube. I carefully measured the fluid I drained out and put exactly that amount back in.
