Ok well I bought another y block and I will be putting it in my truck. I noticed that the original ****** had a little box like thing with two hoses coming off of it then the hoses ran to fittings that went into the block of the motor? Well the new trans is the same way but the motor doesnt seem the same. What do I do and how does this system hook up or work?
I took a few pics. I noticed the old motor has ***tings on where the hoses hook up to into the block from the trans. The new motor doesnt. How does all this woork and go together?
What you have is an oil-to-water cooler for the transmission. This system uses jacket water to cool (or heat) the transmission oil. Your water connection appears to be a tube running up the rear of the block. You need to trace that to see where it connects to the engine water jacket. You should be able to transfer the complete system from one engine to another. While I've only seen one of these in the flesh, I'm not aware of any special blocks produced with special connections for cooling the transmission. You could also tap into the heater lines or just use a conventional transmission cooler, either the radiator bottom tank type or an add-on air-to-oil cooler. Regards, Farmalldan
By using "T" fittings , you can use the existing heater hoses. Those coolers were in use before someone had the idea to incorporate them into the bottom of radiators. 4TTRUK
Well what year offered the trans with the cooler like this? The new motor had an air cooled trans on it. Should I just put that one on? Would they be the same spline and everything else?
Can you pop it off the motor and count the splines? Does it work? What are the numbers on it or the old motor? Looks like it is together in the pics
Not sure what your asking I guess. If no outlets and you want to use that cooler you'll have to t off heater hoses. Not sure if it matters which way the water flows, you could hold a hose to both fittings and see if water comes out the other, if it works one way but not the other you need to pump to that side.
Haven't seen one of those in years. You would be better off to run an after market cooler in front of the radiator. Lot more efficient. Don't use the air cooled trans, they had a lot of cooling problems. Butch
Heater hoses. I hope this helps. The one on the intake of a V8 is the hot one, the cold one comes off of the water pump.
The trans fluid and the coolant flows need to be opposite each other,..in order to maximize the heat transfer. As for a "cooler kit" Hayden makes them in any size you need, and they're available almost anywhere. 4TTRUK
That is a trans cooler, I had one on my 59 Ford P350 stepvan 223 inline six. Now I have a modern radiator with a trans cooler in the bottom tank. The cooler is basic, oil in, oil out, water in, water out. I may still have the cooler in a s**** pile. Most milk / icecream/ delivery trucks had them to supplement the finned torque converter.
So I should just run this one then. Should be fine? Jist take it all off of the old block and put it on the new one. What type of sealer should I use on the threads on the fittings that go into the block?
