He said the fluid is supposed to have a life of 100,000 miles, but he is a Stealer, so that can be taken with a grain of salt. He also said they use 13 quarts of fluid, and flush the four extra quarts through the trans to clean it. This just loosens the materials lodged in the screen, according to him. I have done the drain and re-fill every 25,000 miles, and at 53,000 it has been one of the best transmissions I have ever had, including a Lexus and an Audi in the past. I tow my boat every other weekend also. I sent the fluid from my 52,500 flush to a lubricant testing lab, we will see how much wear metal is in it. I plan on posting when I get the data. I also did the front diff., the transfer case (which had a lot of metal mung on the drain plug when removed), the rear diff. and the engine. All of this was part of my 52,500 service I did last weekend.

Did you get the results back?
