Driving home from college today I noticed that sometimes when I go to pop it into 3rd, it doesn't glide in like the other gears, it gets a bit hung-up and then goes in. Have had the TJ for 2 weeks now, so I don't know the last time there was a fluid change done.
Should I be worried?
It's a '00 TJ, 4.0 - so I believe it has the NV3550?
It takes just over 2 quarts. I also did a flush using about 1/2 gallon of diesel to clean all the old crud out.
so drain old fluid, clean off the magnet (no big chunks was encouraging). replace drain plug, fill w/ 1-1.5 qts of diesel, replace fill plug. start engine, run jeep through each gear slowly a few times with transfer case in neutral.(not driving, just sitting in driveway) drain fluid, clean off magnet. Let it sit for 1 hour with the plug out to clear all the diesel out.
Also while filling the trans back up I used a 3-4 foot piece of fuel line slipped it on the end of the quart of fluid and had my brother squeeze it while I held the hose in the tranny. It takes just over 2 quarts.

It's a 17mm hex bolt. Also make sure you get the fill plug loose before draining it
Best advice on this thread!
Always take the fill plug out before draining. Alot of these plugs have never been removed since new and seize especially on gearboxes with aluminum cases. The absolute best penetrant I've found for loosening stubborn plugs in aluminum is made for GM. AC Delco Rust Penetrant and Inhibitor it's actually made for loosening heat valves but we don't have those anymore.
If it wont loosen it Your Gonna Need a Torch!
Redline MTL is another great choice for the nv 3550. It's only available online n 15 bucks a quart but sure is worth it. My shifting has gotten progressively better over the two months since I changed it with that fluid. Buy 3 quarts so 1 you have extra which is nice cuz you will spill some and 2 bc if it leaks or you need to top it off in the future you can.
