Default Found a good solution.....

.....for mounting the trans cooler, with a little help from my friends.

I will mount it up front instead of taking the easy way out and mounting it under the car on the frame where it really won't do a good job and could end up damaged. I had to be reminded that there is a lot of hot air expelled underneath the car from the radiator, engine block and exhaust system.

The one I have is just too a little too big to fit behind the front bumper in front of the radiator and condensor, so I'll just downsize the cooler and get one about half the size so I can put it up front where it really needs to go. The 4L70E overdrive trans with the lockup converter shouldn't put out quite as much heat as one with a non-lockup converter that will by design slip at least a little 100% of the time.

You can see the top of the cooler here, it is 1-1/2" thick and there is only a 2-1/2" space for it. On the left it's just touching the condenser at the bottom corner, it has to follow the angle of the front bumper and grilles in order to fit.



This cooler is 10" wide (as mounted here) including the mounting flanges and has an 8" core width. I will replace it with one of the same design that is 5-3/4" wide with a 3-3/4" core, it will also be 1-1/2" thick like the larger one:http://www.summitracing.com/parts/BMM-70273/



Should get some pretty decent airflow here and not block too much airflow to the condensor and radiator.



It will mount the same as the trans cooler I have on my GTO shown here, but of course it will only be about half as wide. Plumbing will be done using 3/8" steel hard lines with inverted flare fittings (no rubber hose) like the GTO as well.







Thanks for all the help and suggestions guys, much appreciated.

They're #17770 3" Dynomax Super Turbos, I want to use the quietest mufflers possible and 2-1/2" tailpipes to help achieve some additional noise reduction. Good for an unrestricted 500 HP in pairs which will work fine for my 450 HP stock LS3 engine with headers, but I'm not sure yet if I can get them to fit as they're pretty wide at 11" not to mention 5-1/2" thick.

Once I added the chassis braces shown here I lost about 1-1/2" of room on each side (right next to the lower control arm pivot bolt) pushing the mufflers closer together and leaving very little room for the driveshaft to run between them. Still trying different things on this build.
