Accessing Xdrive Transmission Fill Plug!? Help Needed

cjdzombie · 09-28-2018, 01:43 PM

I'm in the middle of changing fluid in my transfer case and transmission. I'm stuck at the transmission fill plug. I just cant seem to access it. I cut down a 8mm hex key but the damn drive shaft is right in the way. Does anyone have a pointer of trick they used to get at the plug? I'm basically at a stand still until I can access that thing.

You have to disconnect the front drive shaft to access the transmission fill plug, not a big job.

I figured that. I'm going to try and avoid that if possible. I think I might approach it like the transfer case fill plug. I'm going to use a 1" piece of 8mm hex and a ratchet wrench. Maybe I can weezle my way in there that way.

just make sure you get the fill plug out before yo ucrack the drain.

I've made this mistake.

It must be an auto, because on the 6sp manual, you don't disconnect anything... easy access to all of them; just have to remove the metal shield.

To follow up, I ended up just un bolting the drive shaft. It was really simple.
