TH350 trans cooler
 

Speaking of oil cooler lines I seen on class form a while back that a
trans cooler is not needed and should not be used. We have a trans
cooler in a stock eliminator car. Why shouldn't we use one? Thank
you in advance.

In my opinion and experience, there is nothing wrong, no harm done by having a trans cooler.

Again, in my opinion and experience, the harm happens with an overheated trans in the late rounds.

This feedback comes for many years of bracket racing and winning the final where the last 3 or so rounds come quickly.

I continue to say "in my experience" deal is, I always expect to be in the final and have equipment that can do so.

Consider Jeff Verdi who won the Vegas Million with a door car, I figger that car has a trans cooler.

OK, OK, rant over, sorry, no offence meant and I hope none taken. If there is a solid, documented reason not to have a trans cooler I will eat crow.

Yet will continue to have a trans cooler:)

My partner and I couldn't agree on whether or not to use a cooler on our 727. We compromised by using a deep pan with cooling tubes (air) running fore and aft in it. Like this one, but I can't remember exactly. It was 20 years ago. http://www.parrautomotive.com/index....302/prd302.htm
We never burned it up, and went a few rounds a few times. (Dialing seemed not to be affected by heat.) Who knows if it was effective?
Someone just mentioned on here somewhere about ATF temp affecting stall speed. Never thought about that one. Interesting.

I don't run a stocker, but I've always run a cooler on my bracket car. On a stocker maybe eliminate it for weight savings. I run a large B&M cooler and used teflon lined steel braided 6AN hoses. I took the last trans out after 15 years of abuse. Never had a problem, just went to a Trans brake unit I had. Some years 250+ passes changing the fluid and filter every year. I'll keep using a cooler.

Actually, an auxiliary transmission oil cooler really isn't needed. We run an in-radiator tank transmission cooler in our stocker for one reason. The engine will reject heat into the cooling system much faster than the transmission will into an auxiliary cooler by itself. That being said, the transmission will heat up to operating temperature much faster because the water/coolant from the engine washes over the in tank cooler heating the transmission oil faster. Also, if the situation were ever to occur that the need for a cooler is required, the in-tank transmission oil cooler is a more efficient cooler than an auxiliary type.
