Hey guys, I have a 1995 Ford F250 4x4 XL. It has a 7.5 460 Automatic Transmission. My radiator is split and I need a new one. However, I have this line and I DO NOT HAVE ANT TRANSMISSION COOLER LINES PLUGGING INTO THE RADIATOR. The radiator coolant line ports are plugged. I have another smaller radiator in front of the main radiator which I believe is another cooling radiator. My question is what do I do? Do I buy a radiator for automatic transmission and plug the two ports like it is now or should I buy a radiator for a manual transmission with no ports? I'm confused, which is normal for an old man my age, but what is this long line in the picture and should I be worried that I have no transmission cooler lines plugging into the radiator? The truck runs great apart from the radiator going bad. Any thoughts? Please help!
That picture doesn’t show anything about the other “radiator”. Is it the condenser for the air conditioner? Is it an auxiliary cooler for the transmission so the previous owner bypassed the one in the radiator and is only using the auxiliary cooler? If you follow the hose that runs across the top it goes back to the throttle body. The replacement radiator would work for either automatic or manual transmissions. It will also have the port on the filler neck to connect that line.

Buy the correct radiator for an automatic transmission truck. Re-plumb the transmission cooler lines like the factory did. Transmission fluid supply line goes to one of the radiator transmission cooler ports first. The other transmission cooler port goes to the input of the exterior mounted transmission cooler in front of the radiator. The output port of the front mounted transmission cooler then goes to the return line port of the transmission. Someone mistakenly plumbed around the factory transmission cooler in the radiator. That's a big no-no.
Example of how the transmission cooler lines should be plumbed when using an auxiliary transmission cooler:

Thank you so much for your reply! I will try and redo the lines the way they are supposed to go! A small project just turned in to a major one which is tough for an old man but I will give it a go! Appreciate your time!

It's not a huge project, you got this.. just follow the simple diagram and all will be well, I know it sounds confusing but the guys here were helpful when i added one to my truck and it wasn't as daunting as I imagined.
thabks for the pep talk I will try my best to get this!

Send a photo showing the top of the engine. Something that shows the upper intake manifold and throttle body. I am very curious after you sent the photo that shows a throttlebody cooler line. I thought only the 5.0/5.8L engine trucks got those cooler lines. Could be wrong
Thank you I will take the pictures in the morning and post them. The engine is definitely a big block 460 so I am worried now that it has been rigged up wrong by the previous owner. Thank you for your reply,
Grant

The separate throttle body cooler line isn’t going to hurt anything. I procured one from the junkyard and added it to one of my trucks that didn’t come with it from the factory.
I didn’t think they still made separate manual or automatic transmission radiators. At least the last one I bought did not ask me what transmission I had. I just didn’t remove the plugs for the transmission cooler lines.
Just checked it out on my stock 94 F250 460. It goes to a tee in a heater hose which goes to a fitting below the thermostat housing. I'm sure mine is stock, hope this helps.
Yes it does help. It's not used for throttlebody heating as I suspected. Perhaps a bypass path so water flows through the heater core when the thermostat is closed?
Both transmission lines feed in and out of the small cooler in front of the main radiator and I traced them back to the transmission. There is a t in the metal line that comes from the top of the radiator neck and splices into the other 2 what I believe are heater hoses. All I wanted to do was replace a leaking radiator now I have this mess on my hand. For an old man who lives to tinker on vehicles this has taken on a new meaning. I would like to put everything back right. If I get 2 flexible hoses and route them from the passenger side of the transmission and plug them into the radiator and do away with the oil cooler in front would that work? Thanks for any help!
Please see my new pics and post in this forum I am stuck with this project and need help badly! I am older on a fixed income and can’t really afford to take her to a shop! Thank you,
Grant
