transmission oil cooler

[emc2jb6]

does anyone have or has anyone ever installed a oil cooler on a 83fcrb
model bird. if so where did you install it and did you get the benefit
from it that you expected. i have a few leaks in the heat exchangers
under the couch and under the bed so i turned off the valves that feed
this system and now i have a heat problem. what are my options if i
leave this system isolated. transmission temp is running about 200 and
above. have not run it for long at this temp.
