Looks like Trans fluid leaking from cooler

[mick883]

Is this a normal problem? I see fluid on the ground, red trans fluid. It is coming from the front. It seems to be leaking down from the cooler. Do they tend to leak? or do the hoses tend to leak? Just looking for some advice.
If I do have to replace things...where do you recommend getting the trans cooler parts from?

i'd get an upgraded one. the 6.0 cooler is worth it.

Ditto on the 6.0 trans cooler! They are huge and worth it. My lines were leaking on the 6.0 cooler because I used a hose that the shop told me would work for trans coolers. after 25k miles beating up the trans pulling the 5er they started to leak. I just replaced them with real trans hose and hope to never have this issue again!

Also remember that the powersteering system is full of atf so it might be that leaking too. There is a small cooler right behind the front license plate that might be leaking. that is for the powersteering NOT the trans.

Is the 6.0 trans cooler a major change? Brackets? lines? what all is involved?
How much am I looking at?

The 6.0 cooler will bolt in place of the stock cooler. you need a few feet of 1/2 TRANS line (NOT any hose that is 1/2!!) and some barbs to go from 1/2 to 3/8. I paid $50 for my cooler on craigs list. most seem to go for $100 to $300. Even at $200 its worth the cost of doing it if you pull anything.

Very easy install after you pull the nose of the truck off. that was the hardest part for me. Kinda a pain.

You dont need to pull all the front end off. You can just pull that cover off right there when you open ur hood and look down. you can install it from there. Will help your trans a lot. Plus it will like you more
