It was suggested that i mount my radiator over flow and transmission cooler at the rear behind the tires Does anyone have pics of their setup?
This is street / strip setup

How much does each one weigh? I wouldn't worry or even think about doing that on a street and strip car, use your skills for better results

I like to mount the trans cooler under the car and close to the transmission to keep the lines short. I've even mounted them on the crossmember so they come down with the trans when removing.
Mounting in the back somewhere works too. Up under the floor in the rear seat area. Never gone all the way to the trunk. Any place is preferable to all the stuff and lines up on the radiator.
Not sure why it's fashionable to put the overflow in the trunk. Not that much weight and you have a 18' long hose to run and secure.

I don't have the trans cooler fitted at the rear but the coolant overflow can is. I re-located it there after a buddy had a close call with the wall when his head gasket blew. The gasket failed just enough to pressurise the water system and dump the contents out through his catch can. At the time it was fitted at the front. Needless to say a lot have followed suit.

Here's mine. Mounted under the drivers seat inside the frame rail in case failure the fluid isn't in the tire path. No fan fluid has never seen 200 degrees. Doug

I always mount my trans coolers in the back. Working on the truck now and it is just behind the rear end between the framerails.

for those that run a fan on their cooler, is it a pusher or puller style unit ? or doesn't it make a difference ? Any fan will work much better as a puller.

THAT IS EXACTLY why I was asking. This happened to a friend and the fluid under the tires put the car int the wall. I would expect the Trans cooler to also be behind the tire! Would that not be the safest in case of issues?

Would that not be the safest in case of issues? Have to agree it would be the best place for it. It would also need a fan since air flow is limited there. Our trans cooler is in the usual place in front of the radiator for best air flow. It's connected with AN fitting's and hose to minimize the risk and I'm confidant it will be OK. But ultimately, the rear (with a fan) will be the ideal place.

It depends where you monitor the temp. If you set your gauge to read the temp in the O/P line to the trans cooler I see 240 - 260 degrees during a pass. The pan is around 170. The line temp plummets when you lift off the gas. Pretty scary at first but after 10+ years with no problems you get confidant it must be normal

The highest temp I have seen is like 180-190 and that was after hours of crawling in rush hour traffic.
