Sorry for the topic, but where precisely is the fill plug on the T-case? Manual is fuzzy there, obviously don't want DIY'ers:( . Is it recommended removing the skid plate for this job? Thanks!

If you look toward the back side of the transfer case there are two plugs. One is to fill and one to drain. They are really large (7/8 I think) so you can't miss them. Real ***** to put fluid in though

yeah it is a real pain in the !@# too change the tcase fluid.

Thanks for replying! I gotta change my front diff and T-case. I did the rear diff and had the trans done at jiffy-lube as they can flush the whole system with ease. I did the trans myself on the Trooper I had and it was a pain to pump out the torque converter, didn't wanna try it on the massive capacity 'Burban. I may try it again and put in Mobil 1 synthetic ATF this time.

My beast is running nice with sythetic rotella and new oil cooler lines (I installed, what a pain in the a*s):eek: . Appreciate all the technical help here on this forum!:D

Tranny transfusions are easy but don't forget there is a filter in there that supposed be replaced every 30k. Thats why gm didn't put a drain plug on the pan, to make you drop it so you'll replace the filter too and not just the fluid.

First time I changed filter on my '93 I added a drain plug kit. Makes it less messy for subsequent changes. I have done that for all my auto tran vehicles and it sure keeps the floor cleaner.

The best way I've seen for tranny transfusions, is with a flushing machine. It get everything out of the transmission, including the dirt and build-up. They can even pressure check your filter to see if it needs replacement if you want them to. cost about 80.00 bucks around here but I've seen the difference inside a transmission after being done.

Those transmissions filters aren't really much of a filter. All they do is keep big stuff like cats and small children from being sucked in. I changed mine when I first got my truck, but I will never do that again and instead just drain the pan and put new in. I used to flush the torque converter, too but I have heard lately that that is not a good thing to do. All that new fluid can send it into shock.

Well couldn't say about that but I don't see how that new fluid with all fresh additives could hurt anything. I have this done when I buy any used auto truck or car and happy with the results.

i have heard that a transmission will get so used to an old, dirty fluid that when you change it and give it this fresh, clean oil, it goes into shock. who knows if this is true or just bull.

I'd be willing to flush it myself. I know old worned out transmission fluid only leads to failure, so I see it as all a win/win to me.
