The problem with most of your older autos...46rh/47rh/47re were all designed for gas engines...the 47re was utilized for the V10 and the cummins. The two biggest problems were line pressure and the torque powerband. A gas motor idles higher, thereby creating more line pressure at idle, which allows more fluid to cycle through the transmission, keeping it cooler, by pulling the hot fluid through the tranny and coolers. At idle, the diesels didnt have a high enough idle to keep those same line pressures, so not as much fluid moved through the tranny, leaving more heat in the tranny. The other issue is that diesels create much more torque at a much lower rpm...the transmissions were designed for gasserz, and werent engineered to hold up to the higher demands of torque placed on them by a diesel application.
As far as the newer ones, well, the 48res werent bad from the factory, but they werent designed for above factory horsepower applications. Upgraded, they can hold up to 600-800 hp easily.
