| I installed a temp gauge in my single B & M model 70297 transmission cooler last year and was never really satisfied with how hot the transmission would get. This spring I upgraded turbos to GTX2867 and replaced a worn cam / CAS spline and wow the Z pulls great. The problem I now have is the transmission gets really hot ... 272* after just a few hard pulls on a 60* day. I decided to go with twin B & M model 70297. This seems to have fixed my problem. I am curious to see how it performs in 90* + weather. 

The cooler box mounts behind the rear dif using the hicas mounting bolts. 
Aluminum heat shields for GTX2867 and 3" downpipes. 
Heat shield wrap, hoping to reduce some heat transfer to the cabin.
