How important is an external transmission cooler?
Hi all,
I'm curious to find out what people's thoughts are on just how important an external transmission cooler is. Is it absolutely necessary on this car - or is it dependent on your driving style/other factors? My '95 has about 10K on a rebuilt transmission. After reading about the 2-3 transmission flare on this site, I'm not sure it truly had a transmission problem in the first place as it still flares occasionally now. Anyway, my car will not be driven hard nor will it be a daily driver - it's just kind of my toy, but I'd like to keep it for awhile. Thoughts?

Well, there's no absolute proof that a transmission cooler is necessary, nor that it will actually prolong the life of your transmission.
However, I have spent over $14k in SVX transmission repairs. If there is any chance that fitting a $100 cooler will save me from yet another failure then it seems worth it to me.

It will keep your transmission cooler, so it could not hurt.
 I look at them as fairly important.

How important is it to those of us with post 1994 transmissions?

I don't think it is as important as with 92 and 93s. The upgrades to the tranny were done by then. One of the things that will help the most is the filter. It will keep the screen in the radiator from plugging and reducing the flow to the cooler.

On the other hand if you are fussy, and you change the transmission oil every 6 months, then a cooler would be not that necessary. I'm with Phil, I think the cost of fitting one vs the cost of rebuilding the transmission indicates the risk of going without is too high. Joe

Yes get one
I feel a tranny cooler is VERY important. Heat is the number one killer of an autotranny. The heat generated between the 'luxury shifts' is the killer. Either get a tranny cooler installed or some type of modification to make the tranny shift quicker. The simpler solution is to get a tranny cooler.
