Hello,

The material I read said that Ford just post-specced all their transfer cases to DEX/MERC LV. The LV is key here.
About half of the 40 oz. capacity drained out of my 15 year old unit. That is in keeping with every used vehicle gearbox I've ever drained.
I combined Valvoline MaxLife Dex/Merc LV and Wolf's Head Super Universal Synthetic Transmission Fluid leftovers to make the 40 ounces.
Both are synthetic ATFs I've used a lot of before my '05's transfer case.
My unit thanked me with nice sharp clicks into and out of 4WD.

The trannie calls for MERCON V and that is what it'll get.

 

Roger that George. I used a semi-synthetic equivalent to Mercon-V in the trans and it works like a charm. Almost unnoticeable shifting throughout all gear ranges. At the time of purchase, I also picked up 2 litres of actual Mercon-V for the t-case. It was after that when I read online about them "blowing up," so I decided to go to Ford to get their input. Of course, I took all that "blowing up" stuff in stride. Never heard of a t-case grenading because of that. Now, if someone puts 15w40 (for example) in a t-case that calls for ATF, then yes. I haven't done the job yet but I'm going to stick with the Mercon-V for the t-case. Thanks for your input. I wasn't aware of the new spec for the fluid. Much appreciated.

 

I dropped the pan and filter as mentioned above and was surprised that only 4 quarts drained.
It was darkened Mercon V. I've seen it before on 2 other Fords and was glad to see consistency.
I included a 10 oz. LubeGard red.

The vehicle had exhibited a "soft, take-off bump" which matches descriptions of dry slip yokes.
My brief test drive was in frantic traffic. Maybe it was smoother.
I do want to lube the slip-joint. Everything is 15 years old so how wrong can I go?

 

I used that red and tacky grease from Lucas last time I did the slip yoke. Lasted about 6 years now without a bump. Before that I was greasing it every year.

 

I think I have the MOTAL equivalent. What do you think of having a boot on stand-by?

I mean, 15 years old and dry. I gotta get my hands on it before I order a kit (boot, grease and clamp).

I'll let you know what I do.

 

My boot is original and still very pliable. I just checked it last week while changing the oil. They seem to be made to last.

 

Good...but I still gotta get one of those clips and see if my weird@$$ Otiker pliers will work.

 

I just use a big ziptie. Cut it off, slide the boot back, grease, slide boot into place, put on new ziptie and cut the excess off. Have used them for years.

 

Many thanks. I guess it's the CV boots which can't take the zip-ties? Another thing to get the feel of. g'night
