Being the type of person that cannot leave anything alone, the first upgrade is a Hayward trans cooler from Pep Boys, I figured that this AODE/4R70W probably 'thinks' its pulling a trailer compared to a being in a Mustang or another smaller car!
The installation kit calls for a #252, and they had one, but that didnt work for me, not even close..I put everything back together and I went back to PB, and they also had a #394 on the shelf not listed in the installation docs at all, but it looked like it might work, and it did.. I hope the quality of the cooler is better than the quality of their docs and instructions.
The medium duty #403 cooler itself down below
The top side connections (the Brass fittings are in kit #394) On my 93, the top connection is the exit from the radiator and the correct point of connection for the new cooler.
Cost about $50 and 2 hours work, but I'm only a half-fast mechanic
