One side-effect of project is the lingering stink. It's a mess of a project to drain the old fluid out, it gets everywhere......including across the top of an exhaust pipe that runs right underneath the back part of the pan. I wiped it all down with a rag and 409 the best I could when I was done, but still enduring the stink of transmission fluid residue on an exhaust pipe now. Just have to live with it until it finally burns itself off I guess. I did take the car this morning to a DIY car wash and put the wand underneath in the area the best that I could, hopefully that will help.

It's shifting perfectly now. Granted, she's no 4 speed Lexus, but I can't complain either for what she is. I think these days with these modern 7+ gear automatics, their true weakness is when you're puttering around at like 30mph or so....in 6th friggin' gear and going up/down the ladder all the time. Nothing terribly noticeable, but the occasional hiccup is felt. Same as before the change too. But when accelerating, I feel 0% on the gear shifts. Just the annoyingly even-level drone of the engine that makes you wonder if you're driving a CVT sometimes!
It'll take about 3 days for the smell to fade even with the car wash. Not sure which smells worse--ATF or conventional gear oil.

Posted this in December, but adding it to my journal so everything is in a single place:


Gang,

I just completed changing the fluid in the front axle, transfer case, and rear axle and added a Ford Performance cover on the rear axle at the same time. I changed all 3 at 2500 miles, the Bronco now has 5000 miles on it, so another 2500 mile run on all three.

I did not find anything unexpected and overall it was a smooth process--that anyone can do. I am not a professional videographer and so the rear axle is a few videos, but by the time I made it to the transfer case, I had figured it out. Apologies for the multiple videos, bad angles, and having to listen to my voice.

I am happy to answer any questions.

This funnel is a lifesaver - https://www.amazon.com/Hopkins-10106B-FloTool-Filler-Refill/dp/B000EH4UXM

Front Axle Video -



- Amsoil 75W-110 fluid (about 1.2 QTs) - https://www.amsoil.com/p/severe-gear-75w-110-svt/?code=SVTQT-EA
- Permatex 59214 High Temperature Thread Sealant (https://www.amazon.com/Permatex-59214-Temperature-Thread-Sealant/dp/B0002UEOP0)
- I chose 75W-110 because it is the upper viscosity that 75W-90 used to be before the SAE J306 table update in 2005 AND because the capacity is so small. I also had it in my stash--I will switch to 75W-140 when it runs out.

Transfer Case Video -



- Motorcraft Mercon LV fluid (about 1.8QTs) - https://www.amazon.com/Ford-XT-10-QLVC-Oil-Automatic/dp/B07ZTRVLX9
- Permatex 59214 High Temperature Thread Sealant (https://www.amazon.com/Permatex-59214-Temperature-Thread-Sealant/dp/B0002UEOP0)
- I chose Motorcraft Mercon LV versus Amsoil, Red Line, Royal Purple, etc. because there is no combustion by products, the temperatures are nominal, and Motorcraft is cost effective. From my viewpoint, changing standard Motorcraft Mercon LV more often is better than running a premium synthetic longer.


Rear Axle:

- Amsoil 75W-140 fluid (about 2 QTs) - https://www.amsoil.com/p/severe-gear-75w-140-svo/?code=SVOQT-EA
- PTFE Megatape (Gray) - https://www.amazon.com/HERC-15100-1-2X1000-MEGATAPE/dp/B00LO49TV2
- I chose 75W-140 because Dana recommends it for the M220 axle (they also recommend it for the M210 front axle). Any 75W-140 off the shelf (Castrol, Mobil, or Valvoline, etc.) will also work if you do not want to order Amsoil.
- The bolt thread depth in the axle housing is 23mm. If using the OEM rubber and steel gasket with the Ford Performance cover, then you need M8 bolts that are 25mm long. The supplied bolts with the cover are 20mm and they will be too short for the OEM gasket.

Rear Cover Hardware (NEW longer flange bolts are needed if using OEM gasket because it it thicker--there will only be about 6-7MM of engagement and it should be AT LEAST the diameter of the bolt; i.e. 8MM). They are not needed if using the supplied gasket with the Ford cover--use the supplied bolts that come with the cover):

Thanks @CarbonSteel for compiling the info and parts list. You made this very easy. I did mine at 44k. Had a small olive sized glob of paste attached to the rear diff mag, but fluid wasn’t what I’d consider bad. Front diff had a slight smear on the mag. Only took 1 qt in the front, I guess it’s hard to drain all the void volume. Transfer case looked great, but those skid bolts did not want to come out. Used a can of brake cleaner to flush the skid after I was done. 3 hours from setup through cleanup taking my sweet time and a beer break. Also if you have stepped drill bits and a vice the brake line clamps are easy to drill. Low speed low pressure and they won’t twist up
