I picked up a 94 FZJ80 receiving a 5.3 and 4l60 trans. The direction of the previous owner was to eliminate the radiator portion of the trans coolant system to avoid the potential milkshake, but from what I am reading, my use is better suited maintaining the factory radiator connection and finned cooler for proper heating and cooling as per the original Toyota design. Issue is I have not been able to locate the proper flow details/diagrams.
It would make sense that the "hot" coolant would exit the 4l60 and go to the finned cooler in the grille/ds. Cooled coolant would then go from there to the radiator connection on the DS and then out the PS lower rad connection to return back "cooled/tempered" to the trans. This makes the most sense if the radiator design is for heating quicker from a cold start, or maintaining appropriate cooling/heating based on conditions.
Any help in clarifying proper routing would be greatly appreciated.
