trans fluid temps

[team.performance.enhanced]

aight fellas, i have been running the spartan 250 for a few months now and am somewhat happy with the tune. i have a 30' toy hauler that i pull occaisionally and normally run the 250 tune while towing. i have had a problem the last couple of times with the trans fluid getting hot while city driving. while on the highway i have no problems and it will stay around the 173 range. a couple of times though, while driving in traffic, it has gotten up around 210. what is the normal operating range for the fluid temps? would i be better off with the 210 tow tune? my concern with the 210 tow tune is that i thought i heard someone say that it holds the gears longer. in my experieince with this truck, the longer it holds the gears, the more i heat it creates. the only way for me to keep the temps down with the 250 tune is to get past 50mph so the converter locks up and then, and only then will the temps drop. is the 210 tow tune the answer?? or should i be looking elsewhere??

thanks guys.

Its probably more of a function of having air moving through the transmission cooler/radiator than shift points, rpm's or TC lockup.

I pull a 4000 lb cargo trailer with a sound system in it and have run into the same issue.

....And I run the 250 tune....

Your trans is getting hot because the T/C is not locked up. The 210HP tow tune goes thru the gears faster and locks up sooner then the 250. If I was pulling a 30' toy hauler I would use the 210HP tow tune and if I was towing 4000lbs I would run the 275. But thats just me.

^^^ What he said.

Not sure where you heard that the 210 TP holds the gears longer. The shifts through the gears are much quicker, like the race files, and the converter locks up at 45 mph, and will stay locked. The 250 tune locks up at 50 mph like the stock file, and can easily un-lock.

The only time the gears would hold longer is if you were using tow/haul.
