The other day i noticed that i was leaking a lot transmission fluid from the front of my truck. I took a closer look and noticed that there was a leak in 2 of my tranny fluid pipes, so i decided that i will do it the cheaper way and replace the busted lines with rubber hoses. Although me being the moron that i am didnt label them, so now i have two cut pipes and i dont know which one goes where lol. I know it would be to hard to explain so i took pictures and labeled the pipes to make it easier. Pipe A and B connect to Pipe 1 and 2 but i dont know which one goes where. My truck is a 99 durango 4wd, v8 engine. Please help thanks.

 

Is that a 5.9L motor?????

 

Either way, the straight one (#1) is the hot line from the pump (pressure). #2 is the return (cooled) line to the trans.

Not sure on the lines though. You could always find the line on the front of the trans as this should be the Pressure (Hot line) going to the radiator. Trace the line and hook a tube to it, next place the end of the tube into a bucket and place another one under the trucks other line and have someone turn the motor over with the coil wire un-hooked. This should turn the pump enough to see which is your pressure line out to cooler.

Now before you hook up the tubing make sure it is:

1. Rated for petroleum fuel.
2. Make sure the steel line you are taping into (both ends) is flared so after you put the hose on and Stainless Worm Screw clamp on it can't be forced off.

 

Also, the #1 connection has a check valve in it. You can see it between the steel line flared fitting and the rubber line connection crimped fitting. Right in the center of each. If you blow into this line air should get in meaning this is the pressure line from the transmission pump.

Also they make a inline filter you can add in your line before the check valve.

If you hook it up backwards you can burn your trans.

 

Man the D looks like a rusted mess. ???
