Stock trans temp gauge vs Spartan readout

[Antonm]

So the other weekend I was pulling my 18K pound toy hauler fiver over the mountains. And according the Spartan readout the trans starting getting hot (around 220, which I consider hot) but the stock in-dash gauge was well within the normal range (about vertical).
So is the in-dash gauge a big P.O.S.???
Or is 220 within the normal range for trans temp and I'm playing it to conservative???
The truck was pulling fine, and all other temps were OK (up steep grades the oil temp would rise a little as well). It was in the high 90's outside temp though.

Someone out there has got to know how hot is "too hot" for trans temp.

I was pulling an 8k trailer through some mountian samething happened 220 trans temp on 250 tune dpf delete. About 90 out

added lucas oil trans conditioner (sp) then:

pulled same trailer from ca to az about 110 out trans never got hot, just the fuel temp would rise to low alarm....

what does the lucas trans conditioner do?

by normal other temps what do you mean? what was eot? ect? my trans temp has gotten all the way up to 230 so i changed the oil

Oh yeah , You haven't seen my new hauler have you. I'll be down around your way with it around April next year, and staying for awhile.

Now back on topic

EOT/ ECT were both 200 to 210 (up a few steep grades, with a little extra pressure applied to the shinny peddle, EOT would rise, but then go back to the low 200's about equal to ECT) . I have the Spartan set to montior EGT/ boost/ EOT/ ECT/ trans temp/ and voltage. All those and all the stock in-dash gauges were reading normal.

I take it by you changing the oil because the temp hit 230 ,you also believe 22 is hot.

no, i actually changed it because i had the wrong oil in it and was worried that it broke down too much so i had it changed to the right one anyway. 200 and 210 seem low to have a 220 tranny temp imo, when my tranny was at 230 my eot and ect were around the same amount 230-235. it could have been if you were in tow haul then the engine braking seems to cause the temps to rise a little bit but were you in drive or 3rd gear?

I was in tow haul mode but with now real downhills the way I was going at the time

I was definatly in drive. Don't think the truck would even do 70MPH with my 4:30 gears in 3rd (well maybe if I held it at 5k RPM it might , but probably not for long)
