I currently have my trans temp sending unit located in the return line from the coolers back to the transmission. I looked around online and it appears that the reading in the return line would be higher than the reading in the pan in most cases and I wanted to check and see if any has any experience with this to make sure that is accurate. If the return line is indeed a higher temperature than the pan then it would make sense to me that if I can keep the temp in check in the return line than the pan should be good to go also. Any input is appreciated. Thanks
