Truck for a 5000# travel trailer
This is my first post to this forum. I'm sure many of you have seen this type of question posted before, but I'd appreciate your input. My wife and I retired last year and bought a 2011 Gulf Stream...

Yes, this truck does have the 3.42 rear end.
Regarding the acceptable temperature for transmission fluid, we checked internet references on the road and the guidance that we saw indicated that 180-200 F was a normal operating range and that temperatures above ~220 F would contribute to an accelerated breakdown of the fluid. If the temp gets to 250 F, shut it down. Some references show a temperature duration/rate of breakdown relationship.
For example, http://transmissionrepairguy.com/transmission-overheating/
That's "old school" temps.. The modern trans today run in the 200* range normally. If you have an old 3 speed or even 4 speed auto trans, those temps in the chart are more accurate.
Like I said above, I bet if you had let the trans downshift, your trans and engine temps would have gone DOWN while pulling that grade..
Good luck!
