I need to buy a transmission cooler and I want to buy the right thing from the start but don't want to spend too much. I've seen that both Hayden and B&M make good stacked-plate coolers but they are more expensive. How bad are the $20-$30 autozone coolers? Is a junkyard a possibility? I heard that Fords came with tranny coolers but I'm not so sure I could ever put a ford part in my yota!
