Guys I'm curious about the line pressure that an 03 dodge diesel transmission has. I noticed driver fender well was oily and realized the lines had rubbed together and created a leak. Local mechanic told me to replace the worn spots with rubber hose. I did and it worked for months until now. I had the transmission rebuilt and went with a billet torque converter and almost instantly it blew the hoses out. Mechanic who fixed tranny tried to order oem lines but dodge has them on back order. So he replaces the rubber hose with high pressure hydraulic hose. This worked for about 2 days but now has a constant drip. I was thinking of trying a high pressure rubber hose to get away from the wire braid in the hydraulic hose to get a better seal with heavy duty clamps. Does this seem like a good option or should I order the oem lines and wait before using truck again?

 

A union with compression fittings should work pretty well....with no leak.

 

the hydraulic hose should work well if you can get the ends crimped on, i don't imagine the clamps would work very well especially if the hose is heavier than about 2 wire. try a local shop about getting the ends crimped on and score some fittings that will work right from the auxiliary cooler too the trans itself, and go with the hydraulic hose all the way inbetween, thats my plan anyways!
