leak transmission or coolant

[jraker]

I just got back from a trip and my wife said truck was leaking oil. The white paper under the truck indicates red. So I thought transmission. I climbed under truck and found a 1" hard line down by the bellhousing. In that line is a insulated flex connection about 3. 5-4" long. It is leaking from the bottom of that flex connection. Now looking at it from top I could see it and it looks like it y's off and one of the connections goes into the firewall. So now I am thinking this is a coolant line for the heater. I do have red coolant but the fluid felt slightly oily on my fingers. Is this coolant line or a transmission cooler line, I am confused and admit not the most mechanical in the world. Anyway it is leaving spots on the driveway about 4" around right under bell housing. I can see it is dripping from that connection down to the housing so I don't think it is a leak infront of the transmission. Both the coolant and transmission levels are full, do you think I can still drive this around say like 70 miles round trip to go to the pumpkin patch?



Thank you,

Joel

It is probably the coolant line in behind the turbo. I am on vacation so only have this i-pad with me and am not having a lot of luck doing searches with it. Maybe someone else can provide the link for you. Just make sure it is not coming down the front of the engine which would indicate the water pump is leaking.
Your description certainly sounds like the little line that many of us have had trouble with. Go to the pumpkin patch, just keep an eye on the coolant. If it is the hose it is leaking the worst overnight when the coolant is cold.

transmission fluid will smell like shoe polish.

Thank you MWilson, that is exactly it. When I saw part of it going into the firewall I suspected coolant. I think it is most active when it is cool but not sure, I have been in DC all week and just got back at 1230 this morning. I am glad it is not transmission or oil but I will get the new part. Thanks again to TDR for your help.

dont need a new part just tighten the hose clamp..... but i do guess there was an upgrade of a hose or something like that... I just put a little more turns in the hose clamp... just a little... or it will break
