Transmission coolers
Those of you that use aftermarket trans coolers, what cooler do you recommend, are you running the cooler in series with the radiator cooler and where did you mount the cooler on an AC car. I am going with a higher stall converter and need to keep the heat down.

I bought the largest cooler Kragen had in stock, and used some steel strap material to secure it to the radiator support in front of the rad. Run the fluid through the rad first, then the cooler(recommended by BTO).
I have a BTO 200-R4 with a 2200 stall converter, this set-up keeps the trans at about 150 dgrees

Going to run mine without the radiator cooler in line, no reason to add whatever the coolant heat is to the tranny oil. The coolant will be hotter that the tranny juice most of the time, so running it thru the rad doesn't make much sence.

I have a high stall converter in my TH200R4 and the transmission ran 220 degrees after 2 passes with the B&M cooler. Went with 2 18 inch heat sink design dual pass coolers and I haven't seen transmission temps above 150 degrees since (even after 5+ passes at the track)

I always thought the same thing, but I figured I'd better do it the way the vendor says in case something goes wrong. Think I'll try it your way, it does make more sense
Tankers-I would like to have posted a pic, but theres no way I can get a camera into the nose of my 68 for a clear shot

Actually I am doing mine the way grandsport did, Haven't bought yet but found some deals on ebay. The heat sink is the way to go, mount it under the car to take advantage of the air flow under there. Normal operating temps of under 150, it males no sence to run it thru the radiator, will clean up some plumbing and enhance some air flow thru the radiator.

As my wife has explained to me BIGGER IS BETTER, at least when it comes to tranny coolers, get the biggest one, or two, you can fit in. I highly recommend routing it through your existing rad cooler also, your tranny temps on a bad day will far exceed your coolant temps, the extra help makes a difference ( ITS BIGGER THAT WAY) yes honey I heard you.
9 times out of 10 you will cook a trans before the engine

I used a heat sink: mounted it up infront of the rad support on the valence braces: trans cooler mounting
