    Thanks for the part numbers and suggestions.

    Could I ask why you chose the aftermarket radiator vs the extreme duty mopar one?

    I’m new to this, so correct me if I’m wrong please. You have the 03’s radiator routed to the thermostat then to the aftermarket aux radiator, then back to the pan? Would you ever share how you mounted the transmission radiator?

    With adding in the older radiator, are there any other parts I should get in order to retrofit it, or, does it just drop in like the one that came with the 05?

    This is my plan for it:
    -Flush and change the tranny fluid and filter
    -have the pmr pan put on since mine is starting to rust
    -install a new mopar 03 radiator
    -install the mopar extreme duty transmission cooler

    I actually bought the aluminium alloy radiator Renegade 04 suggested:
    https://www.ebay.com/i/272631081960?rmvSB=true
    I then had the radiator been installed in a shop where they measured the hose lengths in order to connect it to the external radiator (the hoses where made by a specific shop). So the transmission oil goes to the radiator (transmission part) first, and then to the external radiator.
    I have it on for 7 months and no issues, the transmission temperature is never too high, and if it does go above 100Celsius it drops quickly.
