man o man i about forgot yes its a cut & past sorry. __________________
after you clean the trans. add this to your*chrysler*trans. an external fluid filter
1. go to auto-zone. get 2210, its called a power steering filter, but it is for transs to. it is for 3/8 tubing. by (magna-fine) be sure to use high pressure hose. Reff:http://www.magnafilter.com.au/magna-fine.html*
2. for other sizes wix 58964 5/16 tube size reff:http://www.wixfilters.com/filterlook...sionfilter.asp
3. i think most chrysler coolant line are 3/8 tubing, but to be sure check it.

 

gravity doesn't apply to this situation. the transmission fluid is moving under pressure from the pump. its not real high pressure, but probably something like 20-30 psi. so its moving pretty fast and its moving up or down or sideways or whichever way is away from the pump.

the factory routing is the pressure line goes in the bottom of the radiator and the return line is on the top.

the reason its piped this way is so that when the engine is off and the trans pump is off, the check valve in the pressure line prevents the cooler from draining back. gravity does apply when the engine is off.

it doesn't really matter that the cooler drains back. that's what happens when you remove the check valve. it doesn't hurt anything, but it might take a moment to recharge the system with pressure.

 

off the top of my head, i don't know which hard line is the pressure line - but be SURE you connect the PRESSURE line to the FILTER-IN

if you get it backwards, the check valve in the filter will prevent flow and you'll BURN UP you trans.

the line with the factory check valve is the pressure line.
if you are not sure which is which, put them both in a bucket and crank the truck, shift to neutral, and see the pressure flow. then label it.

 

I believe the bottom hose is return and the top greasy is pressure going to radiator.

Correct.

 

thanks diverger that is exactly what I was looking for

 

3 last questions:

1.) do these trucks come standard with a cooler. I was under the hood (waiting for the external cooler to arrive) looking at the lines, my top line off the radiator goes to a hard pipe. Following it, it apprears there is a cooler behind the condensor. If this is the case do I need another cooler?
Guess I should have looked first (2 pics)

there's definitely a cooler back there

it also looks like my check valve has already been deleted (maybe I am wrong)

2.) should I flush the cooler? My initial instinct is no, but what do you think?

3.) If I put the external cooler in, should I pipe to the filter assembly first or the external cooler?

 

1 yes some come with a trany cooler. Get a build sheet for your truck. http://www.dodge.com/wccsapp/univers...ull&category=U


2 cant hurt to clean the cooler and the tranny line side of the radiator.

3 do a search here on DF. There are tons of threads as far as adding aftermarket tranny coolers go. And dhvaughan has a good one.

 

Adding a cooler is never a bad idea. Very easy to do. Get a good one - this is not a place to cut corners by going cheap. It is good insurance to extend the life of the transmission - heat is critical and will kill a tranny very quickly.

 

1. you have a factory cooler, which means your truck probably has the "towing package".

2. unless your having transmission problems, or overheating, or unless you just rebuilt your trans - its probably unnecessary. however, it doesn't hurt anything and gives you something to do. use the flush product in the aerosol can and flush it backwards to the normal flow. be sure and blow it all out with air afterwards.

3. plumb the pressure line to the filter first, then the radiator cooler, then the aux cooler. this keeps your cooler cleaner.

BE SURE YOU PLUMB THE REMOTE FILTER CORRECTLY TO THE (IN) PORT !!!
if you route it backwards you'll kill your trans.

here's an old thread with some info and pictures.
