    hello
    I'm putting a chevy six in a 52 international with an 350 automatic transmission, right now i have a aluminum radiator with no hook up for transmission cooling , question is can i go with a separate trans cooler in front of the radiator and not have to worry about frying my trans ? if so any recommendations on brand of cooler?
     
  2. Would probably work,maybe also tie in a temp gauge.

    You should be fine. Just make sure you put the tranny cooler where you get good air flow.

    My son has a 1978 postal Jeep with a 229 Chevy V6 and 350 transmission. It has a separate trans cooler in front of the radiator. It is used daily on a rural route 72 miles long and 600, stops in Florida, It has never had a transmission overheating problem. You should be fine, just make sure use a large enough one.

    Ive gotten cooler coils from the junk yards and plumbed them in. If they look big enough, they probably are. Look for larger size though. In Tucson we deal with 110 deg and drive in it too. I haven't had a problem.

  6. Put a gauge on it an keep an eye on the temps. I imagine the only time you would ever have problems is pulling a heavy trailer during the summer. But then again, if you were interested in pulling you would be dropping in an IH 392 rather then a Chebbie 6.....

    I am running just a cooler on my 50. If you think about it, the one built in the radiator gets pretty hot. Bypassing that heat should not be an issue unless you live in a very cold climate where that may be needed to warm the trans in the winter.
     
  8. Lots of people recommend not using the radiator to cool your transmission and just ruing a separate transmission cooler. I am using the oil cooler off of a late model RX-7 on my T 400 but it may be over kill.

    Hayden makes a pretty good transmission cooler and you can probably buy lines while you are at it. Choose your favorite catalog speed shop or contact me if you don't have a favorite and I'll tell you mine. ;)

    just get a good plate and frame style trans cooler! DONT get the fin and tube.... they are a waste of money and time for running as a trans cooler standing alone.

    Put in front of radiator in good air flow...

    Been done like this on my '56 for 6 yrs and no issues... stock 1969 trans never rebuilt still running perfect.

    Hayden does make good coolers. Hayden number 1679 is a good sized cooler.
     
  11. LOL I used an AC Condenser once in an old Ford I had. They say that heat is the nemesis of an automatic but unless its 104 in the shade and your pulling a pontoon boat it really doesn't take much to cool one.

    Triple digits down here are normal for us... then put 75 to 90% humidity on top.. its hot.... most of the roads here are about 125 to 130 degree surface temps... So yeah I may be a bit biased on coolers... haha.. But keeping a trans in the 130 to 140 degree range keeps them very happy.

    We have 2 seasons... Hot and Mild... and this isn't chicken wings were talking about!
     
  13. We hit trips here as well and humidity as much as 90% but your car doesn't care about humidity it is not using sweat to cool itself. Humidity kills us because we use evaporation to cool ourselves and we can't evaporate when its humid.

    The 140-160 range is actually what I shoot for on a transmission I am not sure why I think a transmission guy told me that once. I think that is the reason that they say not to use the radiator to cool one. That said I got a B&M hydro in the garage that is air cooled and I would not hesitate to bolt it in and drive it. They were a slightly different technology though.

    What kills us here is the extreme difference in temps, hot in the summer ( not as many days as you) and blue cold in the winter. When I am using a transmission cooler once it gets down around freezing I block or partially block it to keep my transmission up to operating temp. Something that you willonly have to deal with if we go into an ice age or you decide to come visit your primo norteño para la navidad. ;)

    Go with one that is a low pressure drop cooler and size it for weight of truck and what you may tow.
    If you have a high stall converter you may want to up the size.

    I second the suggestion to use a plate type cooler. I am using a Setrab cooler on both my cars that I purchased from Godman Hi-Performance, 1-800- 456-2369. I had a combination of 90K on the odo with zero problems.

    I don't like running the trans fluid through the radiator either. In the Hudson because of space I have a separate cooler at the rear with an electric fan that pulls the air through.

    No one mentioned a deep pan with cooler tubes.

    I've used these Hayden coolers a few times, but any similar style cooler will be fine. I suggest building a separate bracket that spaces the cooler away from the radiator if you have room.
    If you wanna step up, get a cooler with threaded fittings and run hard trans line all the way to the cooler, mount your lines in rubber isolator nountings.

  25. Inline 6 or V6? Curious as to why this choice. Different but like it.

  26. Clik I completely forgot about a deep pan with tubes. I have one that I made for a t350 around here somewhere if I haven't given it to someone. You used to be able to buy them cast with fins and tubes.

    Hello Ben
    The IHC six spun a rod bearing, I have not been able to find a source for over size bearings for the IHC 220, Even if i could I was quoted 5 to 6 hundred to turn the crank and buy bearings if possible. I can pick up a running Chevy six for less than that, also making parts easier to find. Of coarse ether way i go doesn't include my labor . I helped my friend build this truck a couple of years ago and he has lost interest and I know it from top to bottom and thought it would be fairly easy to covet it to Chevy power.

    Sorry i should have said it would be a in line six
     
  29. I am not sure where you live but 500 to turn a crank, that guy better give you a kiss first.

    I would convert to GM power in a heart beat[​IMG]
    But you may consider changing the rear end at the same time easy to get gears for a Chevy rear.

  30. ...just mount a good small cooler (a 4 pass one will do) on the framerail beside your trans where it'll get air flow, use short hard lines off the trans with a 5-6" legth of rubber trans line to the cooler, have run dozens of cars/trucks this way for over 30 years with no trans problems.

    Can we see a couple pics of your truck?
