I have a 2001 Dodge Ram diesel 4x4 that has developed a transmission fluid leak at the transmission cooler line to hose "quick disconnect" connection, once I finally got the connection apart, there is an o-ring inside the hose side connector. Is the o-ring available and where? Anyone have the part number for the hose line with the connector, I have searched and cannot find a part number.

I prefer a good quality part, as it is very difficult to get to the trans cooler end and I don't want to have to replace it again.

There are two hoses and I can't remember now which one I need, I think it is the hose closest to the driver side, but if I had both part numbers I could figure it out.

think this is the hot line going to the heat exchanger on passenger side.

 

personally Id use a braided stanless stell fitting with -AN fittings ....... when replacing.

I thought of that, I hate those quick disconnect fittings!, where is a good place to find ss hose and fittings?

ebay, amazon - basically stainless steel fuel line with the appropriate AN fittings.

I have them on my truck - but I didn't do the work so cant  tell you the sizes. 

call a trans builder and get the fitting sizes in and out of the case ......... then route as required.
