with my new bumper my tranny cooler lines are in the way, i just need to cut back the hard lines about 2-3" and run a longer rubber hose.
will there be any problems once the fluid cycles back and there will probally be an air bubble or to going through the system while i change the lines.

also, what type of fluid should i use? i may as well change the transmission filter and the 3qts that come out of the pan since im comming up to 30k miles

 

As long as you don't contaminate the existing fluid with metal shavings, dirt, etc. then you should be fine cutting the lines and extending the rubber hoses.

As for ATF brand, if you can't find any Motorcraft Mercon V, then look for Castrol Mercon V (which has "Certified and Approved by Ford" printed right on the label).

 

Automatic transmission cooler hose is different from generic automotive hose. It is rated for a higher temperature and pressure. Do yourself a favor and use real trans cooler hose - it should say what it is in printing right on the side.

 

alright cool deal, hopefully i can get this done tomorrow

 

I want to do this as well, running without a bumper leaves those hoses right out in the open. Let us know what you end up doing.

 

i cut mine back far enough that they run over the frame rail now.

you can see them in the pics

 

Would it be harmful if I just rerouted mine like that? Or does it require cutting? Well nevermind it won't hurt anything just cutting them down a little bit would it.

 

nope just cutting them down does not hurt anything. ive been running it like that for 2 years now.

 

hey zach, how much fluid loss did you come across when you disconnected the lines?

 

I was just wondering the same thing, I bet if your quick and block the lines it will be very little.

 

Actually, it's not such a bad thing for some fluid to escape when you are cutting the metal lines. This will help "flush" the cutting area of metal shavings, dirt, etc.

 

not even a quart. most i lost was from cooler.

 

Ok another question, this one is pretty easy lol. What fluid is in the tranny cooler, transmission fluid right? lol

 

yep. sure is.

there is also tranny coolant in part of the radiator. see mine i completely by passed the radiator and added another aux cooler. so i have 2 aux coolers and not using the radiator cooler.

 

alrigth cool, thanks zach.
and i will try to get some pictures while im doin this for anyone curious.
