dodge runs a trans heat exchanger near the trans to heat the fluid during warm up. They also have models that run coolant heaters to the rear diff to heat it up....believe it. Its all about efficiency and mpg ratings

Which models have the rear diff heater? I haven’t serviced a lot of Dodge trucks or cargo vans but I’ve only seen that some of the rear diffs are equipped with a cover that have heat sinks.

Give it time - when those control arms start shattering at highway speeds for no apparent reason and the lawsuits start getting filed, they’ll go back to steel or aluminum.

I guess AC Delco gave up on trying to make lines that hold fluid so they've simply eliminated them...

Well it looks like GM just decided to compete with Fiat in the battle for cheapest junk automobiles.

I know this thread is a few months old, but can you clarify how you secured the cooler? I'm looking to do something similar and would like to avoid using the zip-ties through the condenser method that comes with most kits. Thanks in advance for any advice.
