For anyone servicing or possible ownership of a truck that has a AMT, automated manual transmission. Those use 75x90 for lubrication but a special 75x90, totally different additives. The use of standard 75x90 synthetic will damage those transmissions. The Eaton EEO also uses a Special blend. If it is a DT12 transmission there is a cut off date up to 2016 uses 235.11 code 2017 up use 235.16 code. Expensive==a 55 gallon drum figure $2,800.
Good information TS! May save someone a whole bunch of grief. Thanks for sharing.
Does that apply to automated Eatons? I've steered clear of trucks for a long time but wasn't it standard practice to use 50W in regular Eaton manuals? What's different about the automated version that requires the special 75W-90?

The manual boxes ran more tolerance.
