Thank you! Third girl! We have our hands full! Wife is doing good, sore though. Ended up being a last minute c-section.

As for the truck, just ordered a new radiator, should be here soon!

No, couldn't afford it. I went with another all aluminum one I found on Amazon. Hope its decent but I'm going to be the guinea pig on it!

Post up a link to the radiator you bought if you don't mind.

The brand is "Your Radiator". Welds look decent, its a bit thicker and has 3 rows of so I thought I would give it a shot.

You must have bought the last one... it says currently unavailable... lol

Do you mind disclosing the price, since it doesn't show on Amazon?

Price change like stock prices on Amazon. Remember those cheap long tube headers that were $190? They were over $325 yesterday.

Alright! Starting on the radiator today. There must have been a clog somewhere because there was still red coolant in the transmission cooler lines and auxiliary trany cooler and some of it was thicker almost like warm jello. Going to try and flush the stock transmission cooler next, maybe see how much they are and just get a new one.

There is also some type of radiator between the main radiator and the stock transmission cooler. What is it and does it need to be flushed also?

Coolant in the transmission cooler? The TransFlow machine tests the flow rate of the cooler and if below spec the cooler and lines need to be replaced as reduced flow can be a culprit to transmission failure. It also forwards and backwards flushes it out in an attempt to restore the flow rate.

A lot of debris has flown into those cooling fins.
