Acceptable temps?

Acceptable temps?
Now that I got my gauges installed what are the acceptable temps for EGT and trans when towing? The shop mounted the pyro probe in the downpipe after the turbo. EGT gauge goes to 1500 and trans gauge goes to 260. I know it shouldn't get close to that, but at what temps should I be backing off the throttle so I don't hurt the engine or trans?
Thanks

Yikes!! That's really hot!
The EGT pyrometer should have been in the manifold and not in the downpipe. If it is in the DP, you need to add about 200* to that reading and that's likely what you're seeing at the manifold. You want to keep it below 1200*. A short run above that is okay (very short) but sustained temps above 1200* will damage things for sure.
As for the transmission temperature, you want to see it get no hotter than about 210 degrees. The fluid starts to break down pretty fast at temps above 210. As far as that goes, the cooler you can keep it the better. 80-100* above the ambient temperature is a good place to be.
Something definitely sounds amiss with those temps. Is the engine stock? Do you have it chipped? How heavy are you towing? I'm wondering if the gauges are screwed up giving you readings like that....
One thing is for sure, if those temps are right, you're running WAY too hot in both regards.

Lol, I get it now!!
Had me freaking out there for a minute!
That being said, you want to keep the EGT's below about 900-1000* on the gauge with the pyro in the DP and the trans temp below about 200 if you can. Transmission coler would be a good idea when you get a chance, especially if the camper you have weighs much.
At least I wasn't the only one that took it that way...

I would imagine the high temp for a short period is okay as well.
I was told to start to worry at 230 though.
With a load, 210-220 seems normal.

I'd really think about getting that pyro in the exhaust manifold. Those temps can vary a lot between the downpipe and manifold. If they vary 200, you were at 1150, not a problem. If it was varying up to 400, you're at 1350, very long there and you have problems.
I'm glad everything worked well for you on your trip, just stating my opinion above.
