Well to me it looks like Tranny fluid on the paper. I hope the worst has not happened. Which would be that the tranny cooler in the Rad took a dump.Which means coolant is also getting into the transmission.

But I'll also let one of the experts here do some more investigation and or Diagnostics...Just My $.02 Worth.

 

Most of the time it's the flexible rubber section of the transmission cooling lines that start leaking where it's crimped out of the metal pipe. The part is available... They sell the entire metal line with the crimped on rubber section. Which will eventually tend to seep again. You have two real good options.

1. Use a Dremel tool and carefully cut the factory crimp. Peel it off and remove the hose, which exposes a typical hose barb. Replace the hose with the clamp of your choice. Oetiker, screw clamp or spring clamp.

2. Or you can simply cut the metal pipe, put an adapter... 3/8 compression fitting to 6AN, then assemble your own easily replaceable section.

Here's one I did on our Escalade 2 years ago:

 

If it appears the transmission fluid is dripping down from one of the fittings into the radiator, those fittings are readily available and come with an o-ring inside. Very inexpensive.

Here's one of my old ones

 

check the spring clamps on the water pump. i had the big lower one rust apart. from the top 3/4 of the clamp looked perfect the lower 1/4 part i could not see of the clamp was gone. caused a tiny leak of coolant.

 

excellant. I am hopeful it is this "minor" and easily fixable.

 

Thank you. Will do a deeper dive this afternoon. I am encouraged by the replies, that this is "minor" and readily fixable.

 

I was just down in the shop and here's a photo of the retrofit I did on the H2 for the transmission lines. You'll know you can either use standard oil rated lines like on the Escalade above, or the steel braided I went with on the H2 which is a bit overkill LOL

 

It's definitely worth checking where your heater hoses come out of the water pump.... Depending what coolant you have, previous owner could have used an ELC which is red. You can reach over the passenger fender and feel underneath the connections at the water pump, as well as the inline Y fitting that goes up to the coolant reservoir bottle. That's a plastic fitting that's well known to get brittle and crack with age. Dorman makes a nice metal one that comes in a package with spring clamps.

 

[QUOTE=RobertDez;412377]Other than the hood, the body is aluminum. Probably a good thing if you live in the rust belt. If everything checks out and do the routine maintenance on it, should be good to just drive it 😀

Never heard the H2 body is aluminum, It's made of steel.

 

some quick pics...the paper under the front is identifying the fluid leak...








Rarely have i seen a drivers seat this good - especially with 72000 miles. The rest of the interior looks as though it is new.
