Here are some pictures of my tranny cooler set up I took, when I had the motor out for my swap a few years ago.
Cheaper insurance than doing this...
Its a B&M super cooler I bought through Summit. I went to the local hard wear store and bought some 1/4" male to male brass fittings, and cut the factory rubber lines, inserted those into each one, then ran my stainless steel fuel lines to the cooler. The radiator holes that used to be used for the transmission heater, I plugged off using some brass plugs to keep stuff out of it.
This was installed in 2001, never a leak, never a hose blowing off like some see or hear about to this day. If you do the install right, and correctly, and use good quality parts, you should never have a problem.
Happy Driving!
