IMPORTANT NOTE FOR 1993-2002 TOYOTA SUPRA OWNERS If you are a TT or N/A with automatic transmission: Your stock radiator has an allowance built into it for cooling your transmission. If you replace your radiator with an aftermarket one such as this one, this allowance will be removed with the stock radiator. To resolve this problem you must purchase a transmission cooler.  If you have the funds then we highly recomend the transmission cooler with the fans to push extra air through your new tranmission cooler keeping your Automatic transmission running cooler and better than it ever has!  Not to mension added reliabilty!!
