My current Heat exchanger is a little crispy after the 20 years of service and a few years around some road salt. I've seen several listings on Heat exchangers varying in prices from ~$800 dollars to as low as ~$200 dollars and curious if anyone has found a difference between them or has had issues with the different options out there. Trying to save penny's where I can without risking the reliability of the truck.
Eventually I also do plan on adding an additional cooler in the loop but curious if size of the cooler will add (if such a thing) too much restriction.
And lastly, currently I have my Trans Temp sensor located on the output of the trans, but I have read about people mounting it after the Heat Exchanger due to more stable/ accurate temp. I am curious on opinions on that. I tow a lot with it and trying to keep everything as happy as possible, eventually ordering a new valve body is on the list here in the next few weeks and hope to see temp improvements in that as well.
