I have been cruising through the various threads regarding auxiliary transmission coolers. The question I have is what return temperature to target? Is the objective to get the return temperature as low as possible, or is there a preferred operating range?
I checked the shop manual and it does not provide any information regarding transmission fluid temperature operating range.
My '73 340 RR came with the Max Cooling package installed, so it has the 28" rad. On a 75 degree day, at 70 mph, my trans fluid temp exiting the cooler in the rad runs 120-130 Deg F.
Is there any need or advantage to cooling the return fluid temperature below 120?
I have not measured the fluid temp leaving the trans heading to the cooler (yet). What is the upper end of that temperature that one should target for normal operation?
Thanks folks...
