I just got my transmission back in and everything hooked up after having it rebuilt. I bought a can of trans flush and was flushing out the lines before I hooked them up to tranny and had a leak. The line that goes from tranny to the cooler on right side of block was leaking. I took it off and found the compression ring on the brass fitting was cracked. The Dodge dealer wants 180 bucks plus tax for the line! I have checked all the wrecking yards and no luck finding another line. Also no luck so far on finding the fitting or someone that can flare the 1/2 steel line. I pulled the fitting out of the cooler and it is I believe 3/8 male to 37 degree flare. Im not sure what type of threads or on the tranny end of line.
I am thinking about having a hydraulic hose made to replace it except for one thing. There is a coupling on the line right at the transmission that has some kind of sensor on it. What is that? Can I do away with it?
Any ideas or suggestions would be appreciated. I am so close to having it back on the road it is killing me! Now this happens!
If any of you South Texas guys know of someplace that could help, please chime in.
I just hate to spend 200 bucks on a piece of tubing!

 

If you go to a place that build hydraulic hoses that they could just put a new piece of rubber hose and fitting on you old tubing and leave the metal line w/temp sensor alone!

 

I believe the sensor is the tranny fluid temp switch. If u unhook it it 'should' be ok, especially this time of year. Unless you drag around 15 tons everywhere you go! You may not have Overdrive tho!

Flash's suggestion isn't a bad one. My truck had the same fix done to it. and it lasted right up until the time I bought the truck!

 

I'm surprised its even available, they they weren't when mine when bad. Pin holed up by the cooler, what a mess, 20*F, 5th floor parking deck at school. Put it back together with a pipe thread to 1/2" barbed fitting, rung the tube off in a convient place and stuck a piece of 1/2" hose I rounded up at school with plenty of clamps to hold it on there. Fixed the way I decribed it below.

Sorta what I did, I have new 1/2" tubing coming out of the cooler with crush ferrel style fittings with a coupler to the orginal 1/2" tube. I did manage to destroy the other side the line when I swapped the trans, so that side is 300psi rated hose going to the orginal tubing with a flare on it so it won't slip off.

 

I have a couple splices with compression fittings, and one with a rubber hose from when I bi-passsed my heat exchanger. I was worried about them for almost a year and checked them for leaks before I hit the road, but never a problem. I was on a road so bumpy the other night, even at 3mph, I snapped off a battery post, but the tranny lines are still tight. Worse case scenario, a regular 3/8 inch tranny line still has a lot larger inside diameter than the hole comeing out out the transmission leading to the cooler. Because of that restri ction, the 1/2 inch line is pretty much over kill anyway.

 

Its low pressure, common tranny hose and hose clamps will work unless you just want fittings.

 

Make shore you have some sort of lip on the metal hose so the rubber hose don't blow off!

Believe me, they won't leak.......they will blow off with out notice!
