Transmission lines

[mantonetz]

Hello gents,



This is my second post so bear with me. My question is: has anybody repalced the transmission cooling lines due to a leakage? I noticed a few drips developing on the cooling lines. My last truck(95 CTD) did the same but it was totaled before I had a chance to fix it. Is this a common problem, and is it hard to replace the lines? As you can see from my sig, the trucks a 94 4wd.

Thanks in advance!

It's a somewhat common problem. Some folks have found it easier, cheaper and more reliable to replace the metal lines with 3/8" hydraulic hose for their entire length. Most after market AT coolers are hooked up in the same manner.

I had mine replaced by Dodge, they were willing to install the upgraded ones on the pressure side all the way to the cooler. They remind you of the older days when flare fittings etc. were used rather than the mickey mouse plastic insert ones. Mine were seeping slightly, and the dealer said no way. I contacted the zone rep who was more than nice and ordered the change. If you buy them yourself from Dodge, take some oxygen along as they are pricey.

THANKS,

HOW DO TEH UPGRADE LINES DIFFER THAN THE OEM 94 LINES? DOES ANYONE HAVE A BALLPARK FIGURE ON WHAT THEY WOULD COST. I CAN REPLACE THEM MYSELF. YEAH WHAT EVER HAPPENED TO THE OLD FLARED LINES? MY 69 CAMARO HAS THEM AND I NEVER HAD A LEAK?

 

[SRehberg]

The lines from Dodge are approx. $500 for the full set; i. e. both pressure and return. This includes fittings lines etc. They look real similar to the OEM ones, but have the flares etc. They are formed to fit exactly.



I only replaced the pressure side, this is the hottest oil and the failure point that seems to occur.

15 ft 3/8" single wire hydraulic hose = $52

I have quite a bit of experience with hydraulic lines. I do not think that it is necessarily the best way to go on this application. If you can do this at the hose shop, and they are willing to spent a lot of time, then maybe.



Illflem forgot to mention each fitting can cost 10 to 20 dollars, hose does not work without them.



I replaced the pressure line last week. I used the ’95 line because I wanted to install a temp sending unit (no leaks).



The line cost about $110 (including shipping) from DTT.

COOL,

I'LL GIVE DTT A CALL. I'D RATHER PUT ON OEM LINES OR BETTER RATHER THAN RUBBER HYD HOSE. DOES DTT HAVE THE COMPLETE SET UP INCLUDING THE FITTINGS?

Made up lines have their advantages, but I do not think this is the right application.



This is the number you want for DTT 1 866 504 4002 (toll free Canada) or 1 800 922 7782.



This is the factory hose, which includes the check valve and fittings. Takes about one hour from clean hands to clean hands. You will loose about ½ to 1 quart of transmission fluid.



Use care on the transmission end of the line. The line attaches to a "male pipe to flare adapter", which is screwed into the transmission. Do not turn the adapter if you can avoid it. This adapter is typical in aluminum transmissions, and because the adapter is pipe thread (tapered) on the transmission end, over tightening can result in a cracked transmission case. Do not let this caution deter you, but do keep this in mind.



Line cracking is typically caused by vibration of lines and/or rubbing on something. There are at least two clamps on the lines to keep them from rubbing and assist with reducing vibration. You may have to loosen the other line/s to position them properly. This is not rocket science , but it is often over looked.

reddog1,

Thanks, I'll give them a call this week. I with you, I'd rather use somthing equivalant or better than OEM. Just makes sense.

Thanks All!

I had to have mine replaced following a severe leak caused by my own stupidity. I had replaced several of the original leaky fittings with weatherhead compression fittings and one of them developed a leak that I could not stop. The truck was needed the next day so it was towed in and the dealer replaced them with the newer lines.

$700 paid for the tow charge and complete line replacement.

The new lines are good quality with dependable flare fittings.

 

[mantonetz]

Well I traced the leak back to the line that connects to the juntion plate on the pass side. The fitting is leaking... when I push on the line is bleeds like a stuck pig. This line is the one that wraps around the transmission and has the sensor attached to it..... is this the high pressure side? The other side looks fine, what about just replacing the leaky line? or would it be best to replace both lines from the junction plate back?

When you see these parts it will be obvious where they fit.

These were dealer prices 2 years ago, they may be different now.

Thanks guys,

Dieselnerd... thanks for the p/n list. I think for now(Small Budget) I will replace the leaky line. I'll probably have to do the other one next year but that's next year. .

Thanks Again

I've always read that since I have a '97 I don't have to worry about the infamous plastic fittings on my transmission lines. Supposedly 97's and later had better fittings.



Anyways, the other day whilst crawling around underneath the rig I noticed that the fittings on the radiator end had plastic "tabs" on them.



The question is: Are these the "bad" plastic fittings?



Thanks,



Tim

I had DC dealer replace the fittings with a metal fitting upgrade the line itself did not have to be replaced. The ouput line had been replaced when transmission temp gauge was installed so other 4? lines were only ones touched. I paid about $275 did I get rooked? or is there an upgrade fitting without replacing line?

 

[Dieselnerd]

Tim: Short answer, NO. The nylon clip that melts and leaks is at the transmission, especially the front "hot" line. I believe that they were changed to the new style in 1998 not 1997. If you have nylon clips at the transmission and up at the small heat exchanger on the passenger side of your engine that look similar to the plastic ears you saw on your front lines at the radiator, then you have the old style lines.
