What trans temps do you guys see?

    Like it says, you guys with real trans temp gauges.... what temps are you seeing and where is your probe mounted?

    When I'm pushing it good mine warms up to about 210 - 215 and holds there til I am off the lot then falls. My probe is in the test port as I don't imagine it gets hotter anywhere than there.

    I have mine in the test port as well. While plowing I have never had it go above 180* and generally it stays right around 160*. I installed an extra tranny cooler at the same time I had the plow put on, just some cheap insurance.

    Never really see it close to 200* unless I am really doing something stupid.

    JDiepstra, by your question above, are factory temp gauges highly inaccurate or something? Just curious, My 2000 silverado 2500 6.0L has the factory gauge, and it has never gone past the middle ( needle straight up) I don't remember the temp markings on it... Are these factory gauges still a good indication of tranny temps? or are they junk?

    Is is hard to damage an auto tranny if it is never overheated?

    Just curious

    before my aux cooler and aux fan i have had it above 260, and the trans temp warning light would come on and it wouldnt let me shift into OD.. (self protection)

    i installed an aux cooler with a fan mounted directly on it (helps get air into if especially when im driving with the plow mounted, hard to get air flow in it)

    the additions are new for this year.. so we will see.

    Factory gauges are glorified idiot lights.

    I think something was wrong with your gauge. No way you hit 260 and didn't cook the fluid and tranny. IIRC it's good to about 230.

    I don't trust factory gauges.

    Sure, you can damage an auto tranny at low temps. It's not easy if you are running stock power though. You can slip a torque converter, slip your clutch packs or bands, you can snap shafts...........

    Wow I find some of these temperatures curiously low. But thanks for the info.

    How hot is the engine running, I find it odd that no one every talks about engine temps. A trans is bolted to the engine and if the engine gets hot that temp is going to transfer though out the trans,its metal bolted to metal. If it has the little factory cooler in the radiator and the radiator is running hotter than the trans I will almost say the trans will pick up heat. I had a mechanic tell me a trans needs to run about 180 degrees to operate right.

    Very funny. My trans is far from stock and I would even dare say would walk all over a Ford or Chevy trans. wesport

    Just installed a trans gauge on my Excursion late last season and we never got another push in after I installed it. I also used the test port.

    I sure hope so. that low needs to track just a little ferther south and east. Only looking at a few inches here. Maybe the lake effect behind it will get us

    I hope you're referring to the coolant temp with the "needle straight up" - if not, you're cooking that poor trans at around 300*F!

    My truck transmission temp generally ranges from around 150*F to just shy of 200*F while plowing- I like to keep it below 200*F- I've found that 180*F seems to be it's "sweet spot" (not too hot, not too cold)

    I've seen 230 once before-promptly let it cool and changed the fluid after that storm. That was actually on a very steep driveway stupidly plowing in 4hi with 3000 lbs of sand plus the spreader. Normally I see 200 as a high. I have a 98 chevy with a 4l80e. Sending unit is in the pan, aftermarket.
