tranny cooler

[impstocker]

OK, possible dumn question since the last Stocker I built was a stick car, do I need to run a tranny cooler? I know in my buddies Comp car we don't and honestly never look for ones at the track Turbo 350

No.

[Mark Yacavone]

Yes.

My Pro Trans cooler line fittings are plugged, evidently bypassed internally. Ditto my Rossler. No cooler provisions on either. Evidently not needed.

Will,

This is personal opinion, I have no testing to back up my opinion. It simply seems reasonable to me that a trans cooler is a good thing.

My thought is I am always look at being in the late rounds, in the final and if the last two or three runs come close together [which is to be expected] a cooler will be a very good thing.

Consider this chain of events, with a cooler anytime the engine is running fluid is passing through it. So, late rounds, things are happening quickly, on the return road, pulling up in the lanes, moving into the water box, fluid is flowing through the cooler.

That has to be some advantage over no cooling ability. I seems to me the fluid temp has potential to be more reasonable than without a cooler.

Add a deep finned aluminum pan . I do not know of any stock super stock guys running a cooler. The car is not running long enough for it to do much good. The fluid is only being cooled when the engine is running. Like Ed Wright said most race prepped transmissions are plugged and bypassed internally. Also one less spot for a leak.

If you have an in-tank transmission oil cooler (TOC) in your radiator, I would use it because it will help put heat into the transmission faster than without one.

As far as needing a TOC Auxiliary Cooler, I personally think one isn't needed because the transmission will not make enough heat in one pass to require a cooler. But, you also want to be prepared if you have to make multiple passes which will produce enough heat to hurt the trans.
We have used our in-tank radiator TOC for years with no problem.

"be prepared if you have to make multiple passes which will produce enough heat to hurt the trans"

that is my thinking and I always plan to be in the late rounds

I've been wondering for a while if the car might ET more consistently with the stock-type in-tank cooler. Seems like the trans fluid temp would be more consistent, though maybe higher than with an auxiliary cooler.
