I saw that my transmission cooling lines are leaking into the radiator fluid. Is this no big deal or should I go get a new radiator?

This is a simi big deal, nows your chance to install that external trans cooler. You'll have to flush out the cooling system and plug the two bungs. All cheaper than a new rad. It can be fixed at a rad shop also.
But if your rad is pretty old anyway new may be the way to go.

Can you tell me more about the external trany cooler. Where do you mount it and how does it work? I have a 70 Chevelle with a 454 and a 400 tb tranny

Not only is your trans fluid getting into the radiator, it is quite likely that you have water in your trans, too. Check your trans dipstick for oil that is milky looking.

Yes and don't forget to drain the converter also.

The easiest way to get all the fluid out is to go to a shop that has a device that can exchange ALL the fluid in your tranny and converter. A lot of the quick lube place's now offer this service. Get your radiator fixed first then get the fluid changed asap.

Lildog,
Depending on who you talk to in the transmission industry, you might not want to go to strictly an external cooler. Some knowledgable types have told me that not only does the trans "cooler" in the radiator help to cool the trans, but also helps get it up to operating temp in real cold weather conditions. I would say that for most street applications, it would be best to stick with the stock type cooler. An external cooler is good if you are towing, or really leaning hard on the car.
Just my opinion http://www.chevelles.com/forum/smile.gif

Thanks for all your help. I think I will stick with Radiator I have and get it fixed. And I'll check on lube places around here. San Angelo TX
