I tried the inline setup first and hated it, so I went to the local plumbing shop with my sender and found a threaded bung that I welded it on a horizontal plane into the pass. front corner of the AW4 pan. It's really the only place you can install it without the sender hitting something on the valve body, a deeper tranny pan would be nice for both cooling and added fluid supply when on steep inclines for extended periods. I've though of getting another pan and grafting it onto the stock pan for added capacity................
BTW, I feel that the inpan location of the sender gives a more accuate reading of the "real" tranny operating temp. My gauge usually reads about 180 degrees, unless it's 95+ outside and I'm in stop and go traffic or rockcrawling, then it gets up around 200.
