What’s going on here. How does this happen? And has it ruined my transmission?

I find these types of comments entertaining. The AISIN Medium Duty Transmission offered in the 3500, 4500 and 5500 RAM trucks simply does not break. With the straight six Cummins the 6 speeds works great. I tow much more weight than the vast majority on here at 35k combined West Coast with ZERO need for more gears.
My trans temp runs 165 towing or not and when climbing miles of 6% grades it may get as high as 172. OH and the trans is NOT tied to anything other than it's own cooler.
But it sure is nice to have. No matter how flat the Cummins torque curve is.... It will benfit from more gears.
Do some torque multiplication calculations for different gear scenarios for some startling answers as to why.
A 10 speed tranny is better than 6 speeds in a truck just as a 10 speed bike was better than a 5 speed when I was a kid.
Do not fool yourself. More gears will put more torque to the ground going uphill, AND make the exhaust brake work better going downhill.I expect that when Ram finally gets a tranny with more gears......That your opinion will change.
As far as the tranny cooler in the radiator, it is there for a reason.To keep the fluid from running too cold. As far as the risk of it failing... Any part on any brand can fail.... But tranny coolers in radiator failures are VERY rare in any brand.
To the OP, fix it, and move on. It is not likely to ever happen to you again
