Tranny fluid leak... Fixes?

[Acidsniper]

Backed her out of the garage last night and noticed a small puddle of tranny fluid in the front of the truck. Crawled under and noticed it looks like it's coming from the radiator. Is this a fairly common problem or is there somewhere else it could be?

Looking at swapping out the radiator myself I couldn't find any good avenues to get the whole fan shroud off to get the radiator out. Any ideas there?

Check your cooler lines. If its a small leak it likes to travel down the radiator and make it look like the radiator itself is bad.

Reverse should have the most line pressure so clean off with brake clean and do some loaded stands (not a burnout) with the truck and look for leaks again.

It might be just a cooler line that is weeping fluid

Is it just the two cooler lines that come in at the bottom of the radiator? It looks like (based on the drip pattern) it's coming from behind the fan shroud then dripping down on to the passenger side cooler line

Try to tighten the 2 lines going into the radiator. I installed a new all aluminum radiator on my 05 and it was a guessing game at first to get it out. Remove the 2 top hold down mounts for radiator. There is 4 bolts bolted to motor holding shroud. The tip top little piece pops off, then next top piece pops off also, move shroud towards motor and lift out radiator, and of course you need to take hoses and tranny lines off first.

On my '06 I have those plastic quick connect couplers. Can those be tightened?

With that type there should be some o-rings on the end. My new radiator came with new nuts that you have to replace on the lines.

Do you have to use a flaring tool for that?

Also, I was looking online and found what looks like a really good deal on a new radiator but it's only a one core. What was stock in these trucks?
