Transmission cooler
ok...I have a 2013 Grand Sport convertible that is an Auto...we are wrapping up the engine build and installing a 3200ish stall and I have no doubt the tranny will not hot...I want to add a top of the line transmission cooler with Dan and all of that and I don’t know where to mount it or what to buy, or where to even start, keen in mind I have a procharger inner cooler up front...is there ANYONE out there that makes a kit for this common problem, I would really like to have one that mounts in the back somewhere of that will work? I’m also willing to loose the driver side storage bin in the trunk floor if I need to use that space....I’m just really needing to get this figured out this comineerk so I can make full full pulls on the dyno and get this thing tuned...
thanks in advance!

I’m running a Hayden 679 on my 2103 GS with a 3600FTI and it rarely goes over 175*, even in traffic. I have it sandwiched between the AC core and the radiator (since I have the HX core for my blower mounted in front of the AC core) and it fits snugly in there, even with the thicker core of the Dewitt’s radiator, since it’s only 3/4” thick.
Here’s a listing on Amazon:
You can either run as a stand-alone cooler for slightly better cooling (which is how I currently have it on mine) or in series with the stock in-rad cooler (if you live in a colder climate, this is better), in which case you need the Hayden part #397, which simply snaps into one of the radiator cooler ports and allows you to connect the cooler hose to that fitting:

Welcome to the forum. Forget the rear mount. Been there and it's not a good solution. You didn't fill out your profile, so not knowing your location makes it hard to guess what might work. If you live in flat land with mild Summers and don't road race, you can get by without an additional cooler with only a 3200 stall. Hotter climate or mountains will need one.
Right side fender mount with fan in conjunction with the radiator cooler has worked for others.

trans on one side, engine oil cooler on other. I originally kept the fog lights when put the trans cooler. It worked fine. I removed them when I added the oil cooler. I wanted as much airflow as possible and didn't use the lights anyways.

Thanks!
Can you please provide more information on the cooler (part number / brand) ?
