Tranny temp question
I own a 2003 F250 SD 7.3PSD with performance chip, boost, tranny temp and pyro gauge, bully dog performance open air intake, and 4" exhaust. Problem I am having, especially while plowing snow, is the tranny temp gauge seems to be getting pretty hot every now and then, like 220-240 hot. When this happens, I park the truck for a while until the temp goes down and then continue plowing. I don't know if I am having a problem with my intercooler or what, but I just had a new Jasper transmission installed about 3 months ago and no issues until now. Also, this evening driving in the snow and ice, my gauge was reading 180 out of the blue. Any ideas????????? Thanks.

180 just driving does not sound right to me. Jasper might be the name of your problem or a faulty gauge/sending unit. I don't plow so I wouldn't go by what I say but I know Strokin_it does as well as several others. Hopefully they can shed some light on expected temps.

It's possible that you may have a bad ground or loose wire for your gauge. I'd start with that as it's the easiest. Yes plowing is hard on the tranny, but if you don't beat the hell out of it, it should last. During the winter we see alot of plow trucks w/tranny problems.

This evening was the first time it had been that high just driving around, especially with the plow off. I switched my chip setting to stock and it seemed to go down, as I do the same when I am plowing. I was wondering if the snow this evening was keeping the cooler from cooling correctly for some reason. I think I may get a larger cooler and see what that does for the temps. The ground is secure for the gauge, so I don't believe that to be the issue. Like I said, the tranny is only 3 months old and fluid is full and brand new looking.

Just out of curiosity, did they replace or backflush the radiator when the tranny was replaced?

The best way to cool the trans is to put it in park or nuetral (doesn't matter which) and idle at 1200-1500 RPM. This will keep fluid circulating to the cooler.

The sender is in the pressure port.
Do you keep the engine running? If you shut the engine down with the trans hot the heat stays in the trans and can cause damage.
When I was plowing and it got that hot, I just put it in park and let it sit there until the temp came down.
