Tune up time, what to do?

Ok Titan brethren, I have had my Titan a little over a year now, and love it. I figure this spring would be a good time to go over the truck and tune up a few things. I have seen a few threads about changing transmission fluids, but I want to make sure I get the correct information.

Spark plugs-
Transmission fluid-
Differential fluids-

Also, on cold mornings, I notice my transmission is slow to slide into overdrive, is that common? I would imagine it would be, just making sure.

So far I have zero complaints about my titan. I have 5 more years to pay on it, and need to keep it running smooth. Any advice is appreciated. Thanks in advance.

I'm assuming you've done the air filter and cabin air filters already as routine maintenance. You mention "differential" so I'm assuming you're 2wd. If that's wrong, you need to add the front diff and transfer case to the list. Depending on the age of your truck and number of miles, it might be time for a radiator flush and refill. I'd definitely do it if it's over 100k. Go through the front end and look for grease fittings (may be on the ball joints) and hit those with some quality grease if you have them. Check out your brakes (including the e-brake inside the rear rotor "hats" and consider replacing the e-brake shoes as the OEM ones are prone to delamination and cause pretty catastrophic failures if they do.
No special additives for the diffs. I believe the T-case uses ATF, but your owner's manual will have the correct specs. Definitely do both diffs and the T-case along with the trans.

I hear the only thing to do plug-wise is put a new set of the OEMs, which are the NGK Iridiums, I believe.

Sounds like you're on top of it.
