Trans cooler

[Jrosey]

I got a 383 I'm putting in my 69 dart but want to know some opinions should I cool the 727 from the radiator or should I get a trans cooler. It came out of a 70 newport and I'm not sure but belive it originally had a trans cooler because the lines go in front of the oil pan and face pass inner fender. If so how big do I need they have ones on ebay for $40

Huh?
An original radiator from a 70 Newport will have a transmission cooler. And they are more than sufficient unless you're pulling a trailer through the mountains.
Yes, there were a few 70's with standard transmissions and w/o transmission coolers in the radiator but I bet dollars to donuts yours isnt one of those.

i think both lines passed the front of the oil pan. one then had a 90 to go forward to the right port on the radiator. the other did a 180 back to the left then a 90 forward to the left port on the radiator. all this was to allow the lines to flex with the movement of the engine.

Yes it has a trans cooler in radiator but did they have another one the lines don't face the radiator they face the pass inner fender and I seen a pic online like it and it showed another trans cooler in series with the radiator was wondering those if there's any benefit if I went with separate cooler it would prob cost just a little more for a $40 trans cooler than the parts I need to finish hooking lines to radiator

Can you provide a link to the picture?

Pic would help a lot here... sounds like some homegrown add on cooler. If you do lots of mountainous driving or towing, an additional cooler is advisable, just to assure you don't over heat the fluid on longer trips. But as these guys pointed out... stock cooler should be sufficient for the car. It sounds like your add on cooler was before the radiator cooler, which I like because it allows the radiator to warm the fluid, but if its on the inner fender it doesn't have much airflow and really wasn't that effective.

If you are going to run a cooler, do it after the radiator. Unless you're towing, it just adds more connections that could leak, IMO anyway.

Here's Will's thread on a factory trans cooler, may be applicable to what you're dealing with.

I was always under the impression the forward line on trans (fluid from converter) goes to cooler if you add a air cooler it would be in this line then into he cooler in the radiator to make sure the fluid does not go back too cool in colder weather. Because most of these cars now are fair weather drivers it probably would not hurt if done the other way. Unless you are towing heavy (with a Dart?) or you have a really loose converter a additional cooler basically turns into more places to leak.

The trans cooler mfgs recommend installing the cooler after the radiator. I think the design is intended to knock off the engine heat , for a better safety margin when high trans loads occur.

I have a trans gauge and factory cooler in my 2500.The trans temp always follows the engine coolant temp - 15 degrees F, unless under heavy load, then the trans will heat up to engine temp.

I pulled a 48 ft tri axle race car 5th wheel over the Sunshine Skyway last year. That was the only time I have seen my trans temp go past 250,even though my coolant stayed right at 210.The red overheat lines start about 270

I guess in the first couple minutes driving in really cold temps, a cooler would be detrimental. Once the engine heats up, the trans is going to run engine temp - X degrees.

Maybe they do it different in Alaska?

FORTY EIGHT???

Yea, believe it or not, they are only about 10k empty.This one had a workshop inside so was more.
I pull a lot a different trailers for work. Some of the big 5th wheel RVs get heavy.

You For Hire?

Neg I own a repossession agency, I have a few clients that finance RVs. Funniest part about RVs is that you can steal a 500k motor coach in about a minute, if they have a dash mounted ignition.

You can usually steal my truck in 3 seconds, the key is in it. Most every trucking co. I have ever worked for the keys are in them in the yard 24/7.

Uh-oh Stan found a new hobby.

Of course if you want to steal mine right now before I change the clutch would be a good time

 

[65Fury440]

I actually got a truck out of Frostproof a couple weeks ago, voluntary surrender, would have happily paid you to grab it. I wait till after the scales and DOT guys go off,rarely do the voluntaries come back with good tires.

Damn, can you do that job in your home garage?

Yeah I went and bought clutch and picked up trans jack this morning now I need to get my but back out there and get it apart. Its more fun to surf FCBO though.
