it's very short though;About 10/11" long.

I'd be happy wit that...

was under the vx today and messed with the breather tube, theres a white cap on top of the piece the breather connects to.. im assuming thats normal to keep thing out? as soon as i pulled the flexible part of the hose from the piece connected to the frame there was a pressure hiss.. couldnt figure out how to get that white cap off, it felt like it was threaded but i guess not.. wonder if that cap was just stuck down or something... ill check it again tomorrow i guess

so we never got a write up on this huh bart??

a lot of info on changing the diff's...but none for the transfer case...

[etlsport]

the transfer case is super easy.. there are two plugs with square holes.. a 3/8" socket wrench extension fits perfectly in them.. undo the top one first then drain from the lower one... fill with atf until it dribbles out the top one

great....got all the info i need for tranny, x-case and diffs.... guess i just gotta start buying parts now and wait for a day off..

thanks ETL

FYI
I know there are a few post that says the trani requires 10 Qts. mine only took 5 and that was with a complete drain (cooler as well) and new filter, I have yet to recheck it but I doubt it will need 5 more qts!

[etlsport]

i was talking about the transfer case which takes like 2.5 quarts... the transmission is much more involved. if you dont think you put in enough double check your procedure. car should be running while you check and you need to cycle the gears first ..

Even though you drain the trans huge amount of the old fluid remains in there, it's difficult do drain all the old fluid a 100%

I was hoping to get it all, I disconnected the cooler and with everythin unhooked and open I started it up and ran it through the gears hoping to pull out as much as I could, at any cost its shifting a whole lot smoother, not sure if I should attribute that to the fluid/filter or the missing bolts in the trani mount, my guess is they both helped

Good,With a sucking pump you may be able to get almost all the old oil outter the trans

Yesterday i flushed & refilled my VX's differential fluids,the rear had a lil leak & the pinion seal were replaced. I did it because the VX LSD developed a kind of kicking behavior,ever time i make a full stop the differential behaved like the following car just slight tapped your bumper,thought something was going wrong with the differential assemble.

The mech checked the differential for potential damage,hopefully any was found.Said the old fluids were very clean & still with a high concentrated viscosity level.

I add the castroil full synthetic 75w-90 (black color bottle) with a bottle of LSD addditive by CRC industries which meets GM's LSD requirements called K&W,very happy with the outcome

Though i can share this one with guys,specially if any of you are'bout to do the same.

Have good one guys

ok i know this has been beaten a little bit to death, and i have read this and other threads multiple times...
so i finally broke down and spent $120 at advanced auto parts today...

i just wanted to make sure that i got the right things...

front diff-
1.5 qts. of Mobil1 Synthetic Gear Lubricant 75W-90 at GL-5 quality

rear diff-
3.2 qts. of Mobil1 Synthetic Gear Lubricant 75W-90 at GL-5 quality
add 6fl oz. of LSII (limited slip axle additive concentrate) made by BG part no. 328

x-case-
2 qts of Mobil1 Fully Synthetic ATF Mercon V (for Ford, GM vehicles)

tranny-
4 qts of Mobil1 Fully Synthetic ATF Mercon V (for Ford, GM vehicles)

drain bolts- 24 MM socket

so, how did i do?? did i purchase the right stuff guys???
im not very intimidated by the F/R Diff or X-case, but the tranny does scare me a little

Well Jack, are you going to drop the tranny pan and change the filter? If you have never done that, I personally think it is something you should do.

The diffs are super easy. The tranny is a bit of a pain if you are going to drop the pan and do a full service and swap the filter.

You have to support the tranny with a jack stand and drop the big cross member, and then you can get at the pan and drop it. Replace the gasket and the filter and clean the pan and magnet out real nice, refill, and your VX will be a happy camper.

Honestly, it is really simple, it's just messy and hot under the VX. And get one of the those graduated funnels with the lid, tube and valve attached to it from Wal*mart, add some clear tubing from home depot and then filling the tranny is very easy with a helper (one person holding the tube in the hole, another person holding the funnel and pouring the fluid) using the siphon method.
