my friend tuned with me last wk and while we were making some wot runs and with the stock cooler the trans temp never got above like 174*. Granted this was in 76* heat but do you guys think there is any need to upgrade the cooler?

 

Yes upgrade the cooler, your temps will sky-rocket in higher temps. and stop and go traffic especially with a 3200 converter.
