8 Speed 8HP70 Transmission Service
I am very curious what the owners of the 8PH70 transmission are going to do when it comes time to service this very sophisticated transmission?
I have read and heard that this is a Fill for Life Transmission. But in my opinion that is Hog Wash! This is the Real World not Wish Full Thinking Dream World.
So Far I have read the Plastic Pan and Filter are 1 unit.
The ZF Fluid is Ridiculously Expensive.
As for Service Intervals? Nothing!
Even though my Ram is new 458 miles on her... I'm trying to plan ahead.
I have seen the AT pan of many transmissions with only 40-50K miles on them, and I really do not believe any engineer who had seen what I have seen only within those miles, would even think of leaving that fluid in there for the life of those autos.
Any thoughts on the Service of this Transmission is appreciated.
