Antifreeze in transmission.

I had a problem with what I thought was oil leaking into my antifreeze. The color of the oil was black I replaced the oil cooler and ran the truck. It then stopped going into gear. I added more trans fluid and found the oil in the antifreeze again. It appears the prblem was the trans fluid cooler that runs trough the radiator. I drained it agaian tonight and have removed it from the truck. I'll replace it tomorrow. The problem is the water in the trans fluid. I drained the trans and found the color to be chocolate. How much damage have I doe to the transmission. I just had it rebuilt two yearts ago. What is the best way to flush the trans fluid.

Here is a good way to flush the trans. I have done it twice, and it works good.

water in trans is not the worst thing as long as you caught it early and no slipping has taken place. i would be a little bit worried as the color you described was dark and chocolate looking. trans fluid should stay reddish and with water it should look like pepto bismol or close. either your fluid was in bad need of being changed or some slippage has been occuring to discolor the fluid. just do a good job of flushing the old fluid out and see how it goes. you might have to flush twice. good luck.

Install a cooler from a 6.0L/torqueshift and bypass the internal radiator cooler permanently (remove the thermostat bypass on the side of the transmission while you're at it)

Thanks for the information and 4Play, that is part of my dilemma is that the trans was rebuild 2 years ago and the tranny oil is pitch black. I had the tranny cooler replaced 6 months ago and they commented on the some thing. What would cause that. I have not had the time to fush the tranny yet or install a new radiator. I'll let everyone know how I made out.

depending on what trans fluid was used i.e. ATF type4 the dye used in the trans fluid can become oxidized causing discoloration to brown/black. dodge and alot of asian vehicles used type4 fluid and almost all of them will have dark brown/black fluid showing within 30-60k miles. i am sure some brands of ATF use a different dye to color the fluid so this might and i hope why your fluid is dark.

plus it might be hard to tell with the fluid being contaminated already but if it was discolored due to slipping clutches it would stink and smell burnt bad.

The fluid does not smell bad at all and I'm sure the transmission place did not put what was supposed to be in there. I have been talking to the dealer and the price I have gotten for a new radiator is $280. But they wanted $5.06 for mercon 5 trans fluid. They said my truck does not take ATF.

Your truck takes Mercon NOT Mercon 5.

You do not need the cooler in the radiator, bypass it and install a stock tranny cooler from a '03+ 6.0L...no more worries about coolant mixing.

The cooler is about as direct bolt-in as you can get, you'll just need to replace your coolant lines from the tranny, I used 1/2" hose with MPT/barbed fittings in the transmission, the cooler already has barbed fittings for hose.

Plug the cooler in your radiator, you do not need to replace it unless you're having engine overheating issues, or it is leaking elsewhere.

I had already ordered the radiator and I'm stuck with it. I did price the tranny cooler for the 6.0 and it was $511.00. I'm sure I could get it cheaper some place else but I need to get the truck done and I'm still not sure of the condition of the tranns. I have purchased Penzoil ATF to flush the trans first. Is that Ok.

i am not a big penzoil fan but thats probabaly a good investment for flushing trans and without being totally sure the trans will be ok. i for sure wouldnt buy anything expensive untill i could verify the trans appears to be ok. . if it seems healthy after a thorough flushing you could always put better fluid in it afterwards.
