The Super F Synthetic fluid over Conventional Type F gets us that far as with regular non synthetic it was 200 after 3 passes. I have the cooler mounted under the car, facing the ground and it has a fan on it. Its the Derale "atomic" cool that we stock.

I don't have a cooler in the COPO since we can't cool the engine and blower off fast enough to worry about it, and its a T400 with more capacity.

You can be bybassed in the pump and just plug holes as mentioned or loop the lines. I keep a loop on the COPO so I can monitor cooler pressure.
I use your converter. What are your thoughts on synthetic Trans fluid?

Ed, ATI has their own synthetic fluid. Jim has been after me to try some, I've been testing other stuff, I can't give it an honest fair back to back test.

The way I look at this is from my own personal experience.
If you don't plan on going quick, back to back late rounds, either in S/SS or bracket racing, then you probably won't need an auxiliary trans cooler.

Mark, I like your comment and agree. I see no down side to running a cooler and you point out one very positive advantage.

I should add that my car is street legal and will drive to the track as well as run in either GT/ or bracket. Therefore I run a cooler with braided line and -AN fittings. I don't drink beer so I plan to spend as much time as possible with my right foot to the floor.

Personal observation - Any advantage in my case is nullified by my huge swings in reaction times lol. When I go rounds it is usually due to dumb luck on my part or incredible bad luck by my opponents. :p

We have an in-tank trans cooler (water to oil) in our radiator. I like it because it puts heat in the transmission faster than if we were just using an auxiliary cooler under normal operating conditions. The in-tank cooler is more efficient and cools better than an auxilary mounted cooler.

Nelson,

good idea and sounds reasonable

Out of curiosity, how is this different from a factory trans cooler that's mounted in the radiator? I personally like to run through the factory radiator cooler, then run the return side out of the radiator to an external cooler, then back to the trans.

Tony,

I "think" the radiator only cooler has the "potential" to maintain a consistent trans fluid temp. Not to say that temp would or would not be ideal but it would be consistent.

Some things to consider with the subject of trans coolers:

In my opinion, we as racers, can benefit by planning to be in the final at each race we enter. By having a trans cooler of some type we have the potential to keep trans temps under control in the late, quick rounds.
