I have small drips of transmission fluid under the car when it is running... I crawled under the car and I can see some wetness on the transmission fluid cooler lines near the radiator side so I suspect that one of the lines, or fittings, has a small leak... But I am not 100% sure... The transmission pan edges appear to be clean... Are there any other areas that are prone to tranny fluid leaks that I need to check out?

EDIT: I forgot the Dexcool coolant is also a reddish color... I think it's engine coolant, not tranny fluid...

Dexcool is orange in color, and will feel like water when rubbing it between your fingers.

The trans fluid is red in color. If you get some on your finger the trans fluid will be a little thicker and make your fingers slippery like oil.

I posted too quickly... It's dexcool and it's orange... I see a drip-drip-drip when the engine is running... Looks to be coming from the front of the motor (passenger side) so maybe the water pump is going, or one of those "L" elbows is leaking?

Coolant elbows are pretty common to leak on the 3.8 engine. I don't think it's easily spotted without removing the coolant reservoir, alternator, tensioner. Sort of a pain.

I'd probably pick up the elbows and the pump, then return the pump if it's obviously the elbows once you're in there.

Does Autozone carry the elbows? I see the pump and gasket on their website, but not the elbows...

Autozone does carry Dorman brand coolant elbows, but do yourself a favor and stick with GM elbows. The Dorman ones are generally crappy.

So I guess a trip to the local Chevy dealer for the elbows?

OK, I just did the same... Ordered the metal elbows from ZZP eBay Store...

What about the water pump? Is the Autozone Duralast water pump BWP-9016 OK quality for $35??

After looking at what the Azone offers online for my area I would say it looks like the best of the three offerings Not having had a failure of a water pump on either my 1988 or 2005 3.8 motors that I have owned I can't say anything for or against truthfully.
But the higher dollar part has to be better right? Laughing

I can see fluid around the upper coolant elbow on the side that enters the manifold... The wetness is actually on the engine/manifold area directly under the elbow... I can't see the other lower elbow at all... I also see some wet lower on the engine under and behind the big crank pulley... There is kind of a "well" area under and behind the crank pulley and I can see evidence of fluid or oil in there... The areas around the water pump I can feel and see seem to be dry... When I run the motor I get a drip of orange coolant every couple of seconds on the ground... What do you think?

From what you have said it does seem like a elbow leak.
A pressure test would confirm

Yup... Going to borrow a pressure tester and check it out either Monday or Tuesday...

I had the manifold gaskets changed by the Chevy dealer about 5 years ago... I don't see any evidence of them leaking again but I am always paranoid!

Sorry, I never updated this thread... Pressure test confirmed it was the upper elbow leaking on the manifold side... I bought the metal elbows... It was not too bad a job to replace them... No more leaking!!

I had a coolant leak that was troubling to find, and I was going through a gallon of Dexcool a month. I finally found it was indeed the elbow. At Advance Auto Parts here in PA, they had the plastic ones for $4, or you could get aluminum ones for $14.

I ended up ordering these aluminum replacements from Amazon for $8.

I thought I would share this for future reference.
