I have a stock 73 302.

I want to separate the trans cooling system from the radiator.
;)
Does anyone have links on the "How To" on this change/upgrade?

I changed my gearing to help with overheating BUT I know I know I "NEED TO" make this needed change!

Thanks all!! ;D;)

Hi Matt!
This can be a can of worms, with everyone having their own opinion as to the correct way to do it.
Cold country drives or runs possible or likely, or only desert runs?

My own thinking is that the fluid is the consumable, not the trans. As such if I work the fluid hard, but keep the trans cool then I'm OK with periodically replacing the fluid. I prefer to route the fluid thru a Large external trans cooler first, then thru the radiator cooler. The idea being that if the trans is hot then any heat dumped by the external cooler is heat that doesn't go into the radiator, but if the trans is cold that the radiator will heat up the fluid and help warm up the trans.
Not everyone agrees with that, and depending on their location and use their idea may be better.

Most ideal would be to put the external cooler on a thermostat so that it isn't in the system until it is needed.

Good call on the can of worms
I just did the stat experiment with a rad bypass. What I have now accomplished is less spread between the 180/190 to my high temp. I do not like a high of 210. My next iteration will be no stat and no rad and see if I can hold the temp at 180/190?.
This is not my first deal. My most successful setup is on my '96 and it had 2 coolers up front (1 with a blower), no stat no rad and a 180 blower switch in the pan. It never gets above 200 on a 100 deg day in the deep sand/silt

And for sure warm weather guys sure do not need the rad connection.
And if a stat is desired look at all the options and choose one that is full open to the cooler at a temp around 150/160. The tranny should not complain with that kind of temp and you will get a bigger spread to the high end.

BTW, read again what ntsqd just said below. Others with little experience would benefit. (Let me translate: temp in the pan is always correct).
