At 170k miles I changed my oil and came across some fluid residue...
one being oil coming from the timing cover
The other being transmission fluid coming from between the transmission and extended housing (2WD)
YAAAAAY! -__-
This coming up week i’ll be replacing the timing cover gasket.
I was planing to do that and go ahead and do a timing chain kit at 200k miles but i’m not going to have the time for all of that this week since I’ve been working out of state down in GA....so that’s going to have to wait.
I’ll share some pics when I can.
(I also bought a new tool for this job :D)

I start on it tomorrow!
I bought Genuine Mopar Coolant 68048953AB, the timing cover gasket (as shown below), and a seal kit that includes the crank seal, oil filler neck seal, and two other seals as well as a small tube of RTV
New tool that I purchased is a coolant vacuum refill kit/pressure test kit, to make sure I have no leaks and no air pockets when refilling :cool: (I’ll share the link of the one I purchased)

Just an FYI... the timing cover gasket I purchased will not work with the 3.7L timing cover. 3.7L timing cover has grooves for the coolant inlets which use their own preform gaskets. The 4.7L timing cover does not have the grooves so the timing cover gasket I purchased would work perfect with the 4.7L timing cover....and I’m pretty sure the 4.7L timing cover fits the 3.7L. (I may be testing that next year when I hit 200k and do a timing chain kit)

Well.... another leak!!
After traveling from GA back to NC, I pull up in my driver way. Take care of a few things around the house, come back to my Nitro and their’s some drips on the ground below the bumper.
I crawl underneath and take a look....
EVERYTHING underneath is coated!
I stick my finger in the fluid and it’s a dark red almost brown color. ( either P/S or Transmission)
I check my P/S fluid and the fluid level is good.
I do a further inspection and find that my transmission oil cooler is leaking -_-
Found an aftermarket HD transmission oil cooler kit for roughly $70.
Going to install it tomorrow and clean everything up. Then see how it goes

I purchased an aftermarket HD transmission cooler. The little gaskets OEM part# 68338217AA for the oil cooler lines to the oil cooler were not available at any part stores.
Was told I would need to purchase the lines (from the bypass valve to the cooler) to get the gaskets... roughly $100 and would have to be ordered.
Gaskets on eBay are roughly $10/each (need two)

I traveled 4hrs back to GA for work.
Get to my hotel and double check for leaks...
Leaking from the quick disconnects now.
Also.... does anyone know if their is a shaft seal that goes between the transmission itself and the tail housing? (RWD 42RLE Transmission)
TIA

I do not see one in the parts manuals. Just a bearing.
