I'm a little **** about servicing auto transmissions. I've never lost one with 40 years of towing because of what I call over servicing. I have always replaced fluids and filters before any long tow or every 2 years at minimum. Our 04 6.0 diesel had 5 services in 8 years same with my 5.0 Gas in our 1996.

OK what do I do with this one. I doesn't even have a dip stick I can find just to look at the fluid. Anyone out there have a clue? I won't need one for a while since it's only 6 months old ................BUT.......? thanx

 

The transmission is filled with Mercon LV or lifetime fluid. My 2011 owner's guide says to perform a complete flush and filter change at 150K miles under normal driving. I think severe duty still defaults back to 60K miles.

 

I read that in the owners guide too, but like I said I worry about that 1 item more than anything else. After warrenty I could replace a turbo or 2 but AT's are more than I'd like to handle.....Lifetime is a funny/reletive thing....Also sounds like a Dealer Deal.....Thanx for the reply....

 

I agree, lifetime doesn't exactly give me a warm and fuzzy either. I don't tow and haul very little but I intend to have it flushed at 100K.

 

Crawl under truck and on right front of transmission case is a plug that you take out and it has trans dipstick built into it!
