I'd get the largest regular type one that will fit in front of your radiator fins & you'l be fine if you get a large one & I plumb the hot fluid in to the top of the cooler just like hot coolant goes to the top of the radiator. A bit picky but that's me live every 24 hour block of time like it's your last day on earth

I would keep it through the tranny heater for now, most foot brake race converters and trannys don't usualy get hot enough to use a auxilary tranny cooler If you don't have a tranny temp. gauge buy one now and see if you really need the extra cooler, if it runs under 240 F at peak don't add one ATF needs to be at 160 + F to start to work properly Mr.Cab Racing and winning with Mopars since 1964.

They are pricey through the dealer though. I bought my firs one for around a hundy in 04'.. Now my dealer cost is around 189.. I just pulled one at a pick and pull... Less then $15.00..

A bit picky but that's me You can't compare the engine radiator to a transmission cooler that way. You'll want the transmission pressure line coming in from the lowest linefitting on the cooler to properly/quickly expell any air present in the cooler. With an engine radiator you indeed do want air to end up in the radiator as that's where the vent/cap is located. On a transmission the vent is in the transmission itself, not in the cooler. So that should be 'airless'. I reality it's probably not that serious as the line pressure and flow in a transmission cooler is usually high enough to always push out any air either way. My 2 cents anyway. BigBlockMopar.com

Hard lines would be best to use. It is a lite extra money and time to bend them but worth the time in longevity. The lines I run out of the stock cooler go over the rad support to avoid road debrise. This is how it is done on the OE extra cooler on my '78 Cordoba that came with a 400 P code engine.

I use a B&M trans cooler on both of my street cars, its the largest one they sell. Both cars have 8 inch convertors and I drive both cars a fair amount, just drove my Challenger to Vegas for the MATs and put on over 600 miles. The trans fluid has about 4000 miles on it and looks like new. 8126071-IMG_1273.JPG (31 downloads)

I beg to differ with you on the cooler the fluid the better comment, most ATF has additives in it that are based on general automotive use,based on 160 F operating temps according to Valvoline techs . I bought a new 1998 1/2 Ram 2500 24 valve CTD automatic with the trailer towing package, I installed several after market gauges including a tranny. temp gauge in it, that trucks tranny temps would never exceed 120 F when running empty, the most I ever saw was 230 F when towing my enclosed 24 ft. car trailer at 70+ MPH up the 17 mile long Baker Grade in SO CA Mojave desert in the middle of the day in August, 117 F outside air temps. The fluid would start to go darker as soon as I changed it in the winter or summer, I was told it was due to the fluid temps being to low I did notice the tranny fluid stay brighter if I changed it just before going to a race and back It would get darker after that driving it around town easy When it comes to lubricants warmer (140F+) is better than cooler(below that temps) All the dyno tuning I've done on motors show that they make more HP and torque with hot oil (160F+, the hotter with straight weight oil ) the more power they make Mr.Cab Racing and winning with Mopars since 1964.

Also no rubber lines, steel or I used PTFE braided lines. http://perma-cool.com/ Last edited by gregsrt; 04/28/14 03:02 AM.
