I was driving up a hill earlier today and the Jeep wasn't wanting to go... then it started stuttering a bit. Like almost bucking, but not quite. It's making me a bit worried that the transmission is starting to go. The shifts have been a bit rough and slow lately, as well as the weird RPM climb then immediate drop that I experienced the other day. Any ideas? No CEL or anything..
Test TPS?
Adjust TV cable?

Fluid level and condition? Use only Dex/Merc fluid. A drain and fill is easy as there's a plug on the pan. You'll need to have about 4 quarts handy for refill.

I've done the cable fix, and I'll look into testing the TPS.

So I just got home and checked the fluid... I figured out two things... there's nothing showing on the dipstick, and is the dipstick end supposed to be metal? I don't have a plastic handle, but a metal ring on the end...
And I also found this mess:
No idea what it is... or where it was coming from. Right under a hose labeled "heater" which I'm assuming refers to the heater core?

Anyone know the best way to get rid of the sludge in my 4.0? I was replacing my valve cover gasket and noticed a lot of build up. I removed most of what I could get but I'm gonna change my oil too and I'm wondering if there is a certain oil I need to use or an additive that will break it down.

Did you check it running, warmed up in neutral? If there's nothing showing on the dipstick when checked right then something is wrong.
(Even if you check it wrong I think something should show on the dipstick)

If you want to get extreme you could add some seafoam in and run for a hundred miles then change the oil again. Or just do it right before an oil change.

Sludge is like arterial plaque, easier to prevent than manage, change your oil every 3k. Best way to get rid of sludge is tear it down and boil it out. The cooling system can't be in much better shape either.

You think it would be better if I changed the oil and put Seafoam in it, drive it a while, then change it again and use a more expensive oil?

Cruiser said it took about 4 quarts just by pulling the plug... when I pulled the plug, I only got about 2 quarts (half gallon) out... so, not wanting to over-fill, I put in 3 quarts, then checked the dip-stick right after... and it's way over the full line. That was with the engine off though. So how should I check it to make sure I put enough/not too much in?
