Just bought a Mishimoto radiator for my Automatic 1993 Sc300 and was wondering if theres a transmission cooler built into the stock one? If so how would i go about adding one?

 

yes there is, you'd need a standalone cooler. I don't know the details on how its done. I just had my radiator crack on me but I chose to just get a replacement rather than an upgrade for this exact reason.

 

^^ This. You can add an external transmission cooler (Derale, Hayden, etc.) to your aftermarket Mishimoto radiator. This is what Supra MKIV owners do when they upgrade to an aftermarket radiator since only the OEM or OEM specification versions were offered in A/T specification which have integrated coolers.

 

Good morning 2jzBranon,
All you have to do is take the radiator out of the box and on the bottom of the fan side are two connections that the transmission cooler lines connect to. Unless you have ordered a specialty radiator for a manual transmission you will have those openings and as Kahn suggested you can always add an after market cooler. I believe all after market radiators come with these transmission connections.
