I'm in the market to change out the stock trans cooler for a bigger unit. The stock one is tiny and located right behind the chevy bow tie, so it dosent get good air flow. There are many brands out there and I want to do it right the first time so help me choose a good one.
What do you use?

Thanks Mike

yeah that one, although if you live in a warm climate, you don't really need the thermal bypass.

this is cheaper: http://cgi.ebay.com/ebaymotors/TRAN...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

I've got that Tru-Cool 40k unit with bypass, +3qt pan and an external filter on my 80e and it literally takes an hour of heavy throttle to bring it over 180*F at the test port. Now I don't have a whole lot of power on tap, but I really don't have an issue trying to wring what I can from her.

600hp/700tq numbers would be a totally different ball game.
