The line from the tranny to the heat exchanger (the one with the temp sensor) is leaking. At some point it has been patched with a short section of flex hose. There is a hose barb type fitting threaded into the tranny which I need to remove. I am wondering if I am going to need a fitting in order to connect a new OEM type line to the transmission or will it screw directly in?

Good question. The stock tranny lines on my 1995 2500 developed a hole where the tranny line had been rubbing against something and I pulled the lines out and replaced them with high-temp rubber line, and I wish to heck I hadn't done that. The stock lines are great except when they get a hole from rubbing against something. I should have just patched mine. Twice since then my rubber line has come off of the hose fitting and I had to get towed back home. I finally took the brass fitting and soldered a small ring around the end, so clamping would be more secure. So far so good.

 

A pic (or multiple pics) would help here, as I'm having trouble visualizing this. Are you saying that the barb fitting is going directly into the trans case, with a rubber line going to the remnants of the OE hardline that goes to the heat exchanger?

Dodge changed the case connections sometime during the 94-98.5 series - does your other cooler line use a quick-connect fitting or a flare fitting where it returns to the case? If flare, you will need a fitting to convert the case thread (which is either tapered pipe or straight pipe thread) to an inverted-flare fitting. The generic transmission-supply part number is 22996C, and as I recall it is 1/4 male NPT to 1/2 female inverted flare. Dorman offers that fitting, and the chain parts stores are often quite proud of it. You may be able to get the same fitting cheaper at a Parker hose dealer(https://ph.parker.com/us/en/brass-in...ngs/48ifhd-8-4). I got 22996C's from cobratransmission.com and theirs have o-rings where the actual machined inverted flare should be - I would not have ordered Cobra's had I known about the o-ring before ordering (Parker's and Dorman's are all-brass). Due to a line rub-through, I recently replaced my OE quick-connect lines with the flare-connect lines and they still leak slightly at the flare connections from the lines to the 22996C fittings. I'm going to replace the hard lines with a push-lock style hose kit.

Thanks for replying. Thanks for the info. I do need the fitting and you're quite right about the parts stores being proud of it. Most want about $40 for it. Found it at Rock Auto for $25 which still seems like too much but I bit the bullet and ordered it.

 

Texasprd, I don't have any pics. I have a Mag-Hytec trans pan, and the fitting is not a barbed fitting--it's a smooth on the O.D. I completely removed the original steel lines and replaced them with high-temp rubber. That was about 10 years ago, and so far no problems, except the two times that the rubber hose came off the "pipe" of the smooth brass fitting. Before I soldered a piece of copper wire around the O.D. I used to check it every few months to see if it was starting to move. But it hasn't moved at all since I soldered a ring around the OD.

 

Robert, I was asking Glockrow for pics, though I guess I don't really need them any more since he confirmed that the flare/pipe adapter is what he needs. Thanks for the description, though.

Glockrow, I found that fitting for 16.85 ea. with a Google shopping search - if RA hasn't shipped yours, you could save a few bucks. I don't know about the delivery time frame from that source, though.
